Abstract
Perfluorochemicals (PFCs) are wide-spread contaminants on a global scale. There is an increasingly growing number of data on environmental occurrence, sources and risk of PFCs to humans and aquatic biota in highly industrialised countries but inadequate information exists for less industrialised regions. In the present study, concentrations and profiles of PFCs were examined in surface waters (rivers, lakes, streams, coastal region of the Baltic Sea) of Poland. PFOS was the dominant compound found in water at most of the sites surveyed and its concentration varied between < 0.5 and 150 ng/L and next was PFHxS with < 0.25 to 110 ng/L, while at much smaller concentration of < 0.5 to 18 ng/L occurred PFOA. The long-chain carboxylates (C11-C16) could be found only in water of a drainage ditch near to the Sarzyna site, i.e., PFUnDA occurred at 0.17 ng/L, PFTeDA of 0.06 ng/L, PFDoDA at 0.1 ng/L and PFHxDA at 0.12 ng/L. PFDA was found at several locations in the Gulf of Gdansk and its concentration varied between < 0.01 and 0.07 ng/L. The profile of PFCs in surface water at several sites of Poland with PFOS as a major compound, followed by PFOA is similar to that reported for other countries in Europe as well as for India, while this is different from that of Korea, Japan and the USA, where PFOA was the predominant contaminant.

Abstract
The Japanese Kanechlor technical PCB formulations such as KC-300, KC-400, KC-500, KC-600 and KC-1000 have been examined for possible contamination with by-side PCDD/Fs. 75 PCDDs and 135 PCDF have been determined using isotope dilution, separation and enrichment on silica gel impregnated with activated carbon, and final HRGC/HRMS measurement. MonoCDDs to OCDD were absent in KC-300, KC-600 and KC-1000. Tetra- and PentaCDDs occurred at > 1 ng/g in KC-400 and KC-500. The Kanechlors were contaminated with nearly all 135 PCDFsw. In parallel with an increasing degree of chlorination of a particular Kanechlor formulation examined increased also the content of more chlorinated PCDFs. In term of total dioxin-like toxicity and TEQ loads the KC-500 contained highly toxic PCDD/Fs at 270 ng TEQ/g and followed by KC-400 with 269 ng TEQ/g, KC-600 with 188 ng TEQ/g, KC-1000 with 164 ng TEQ/g and KC-300 with 79 ng TEQ/g. From 99.5 to 100% of PCDD/Fs toxicity found in the Kanechlors was from PCDFs.

Abstract
Larch Bolete can be classified as a mushroom species accumulating Hg in the fruiting bodies. Our results did indicate diversity of Hg concentrations (p < 0.05), depending on a site of collection of Larch Bolete fruiting bodies as well as the lack of any statistically significant differences in soil mercury contamination among the examined sites. Values of 1.0 microg Hg/g dw for pool of caps and 2.0 microg/g dw for a single cap of Larch Bolete are suggested as threshold concentrations implying Hg baseline level, while greater value could imply contamination due to the site pollution.

Abstract
Based on ICP-MS, ICP-OES, HG-AAS, CV-AAS and elementary instrumental analysis of King Bolete collected from four sites of different soil bedrock geochemistry considered could be as mushroom abundant in certain elements. King's Bolete fruiting bodies are very rich in K (> 20 mg/g dry weight), rich in Ca, Mg, Na, Rb and Zn (> 100 microg/g dw), and relatively also rich in Ag, Cd, Cs, Cu, Fe, Mn and Se (> 10 microg/g dw). The caps of King Bolete when compared to stipes around two-to three-fold more abundant are in Ag, Cd, Cs, Cu, Hg, K, Mg, Mo, N, Rb, Se and Zn. King Bolete collected at the lowland and mountain sites showed Ag, Ba, Co, Cr, Hg, K, Mg, Mn, Mo and Na in caps in comparable concentrations, and specimens from the mountain areas accumulated more Cd and Sb. Elements such as Al, Pb and Rb occurred at relatively elevated concentration in King Bolete picked up at the metal ores-rich region of the Sudety Mountains. Because of high bioconcentration potential King Bolete at the background sites accumulate in fruiting bodies great concentrations of problematic elements such as Cd, Pb and Hg, i.e. up to nearly 20, 3 and 5 microg/g dw, on the average, respectively. The interdependence among determined mineral elements examined were using the principal components analysis (PCA) method. The PCA explained 56% of the total variance. The metals tend to cluster together (Ba, Cd, Cs, Cr, Ga, Rb, Se, Sr and V; K and Mg; Cu and Mo). The results provided useful environmental and nutritional background level information on 26 minerals as the composition of King Bolete from the sites of different bedrock soil geochemistry.

Abstract
Chloronaphthalenes form a class of compounds consisting of 8 CN homologue groups and altogether of 75 congeners, which used have been most extensively in 1930--1950. An investigation have been performed on the possible origin of unidentified by name technical chloronaphthalene formulation unlawfully imported recently from the United Kingdom to Japan. Principal component analysis (PCA) and Cluster Analysis of chloronaphthalene congener isomer-specific and homologue classes' compositional HRGC/HRMS data of imported CN formulation and of certain brands of technical CN formulation called Halowax (Halowax 1000, 1001 and 1031) enabled to identify that unnamed product is not Halowax 1001. A less accurate multivariate examination based on CN homologue classes patter did indicate on large similarity between unlawfully imported technical CN formulation and Halowax 1001 (manufactured by the Koppers Ind. Co., USA), while a more accurate based on CN congeners pattern differentiated them as to of various origin mixtures. Based on chlorine content of imported CN formulation (50-52%) and its no similarity to Halowax 1001 it seems reasonable to conclude that unnamed CN mixture examined could be a sample of stockpiled Seekay wax R93.

Abstract
This article reports background concentrations of Ag, Ba, Cd, Co, Cr, Cs, Cu, Ga, Hg, Mn, Mo, Pb, Rb, Sb, Sr, Se, Tl, V and Zn in caps and stalks of M. procera collected from four spatially distant sites across Poland. The elements were determined using inductively coupled plasma-mass spectrometry (ICP-MS), hydride generation atomic absorption spectrometry (HG-AAS) or a cold vapor atomic absorption spectrometry (CV-AAS). Copper, zinc, rubidium, selenium, chromium and cobalt were the most abundant amongst elements determined in this mushroom. Some elements (Cu, Zn, Rb, Se, Pb, Hg, Cd, Mo) occurred at greater concentrations in the caps than stalks of M. procera and some (Ag, Ba, Sr, V, Tl) dominated in the stalks, while for some other this proportion was similar or varied (Mn, Cr, Co, Ga, Sb, Cs) depending on the sampling site. For elements such as copper, zinc, rubidium as well as selenium some spatial similarity in distribution and/or concentration values both in caps and stalks was noted. Cadmium and lead content in caps of M. procera was usually below the European Union tolerance limit value of 2.0 and 3.0 microg/g dw set for cultivated mushrooms, respectively. These two toxic metals have been found in elevated concentration in M. procera from unpolluted stands outside of Poland as reported by some authors, which implies the possibility of relatively high background levels in this species.

Abstract
Bivalve mussels are usually used for biomonitoring persistent toxic substances (PTS) in coastal ecosystems. Nevertheless, these organisms, which live attached on hard substrates, can be found along the sandy coasts only on human manufactured products. In this work different species collected in the Gulf of Gdańsk were compared to evaluate their suitability for monitoring PTS pollution at a local scale. The clam Mya arenaria seems to represent an excellent indicator of sediment pollution, mainly for organotin compounds which are selectively bioaccumulated. Organochlorine compounds are bioaccumulated in the different species mainly in function of their lipid body burden. Habitat conditions (salinity, substrate, pollution), however, strongly limited the occurrence of different species in the sampling sites; the most ubiquitous species, the common shrimp Crangon crangon, resulted therefore the most suitable to be used for the comparison of PTS pollution in this aquatic environment. Although the blue mussel (Mytilus trossulus) was confirmed to be a very useful sentinel species to compare pollution level inside and outside the Gulf of Gdańsk, we recommend the use of other species to give a more detailed picture of the pollution situation in coastal areas.

Abstract
Concentrations of Ag, Al, Ba, Ca, Cd, Co, Cu, Cr, Cs, Fe, Ga, Hg, K, Mg, Mn, Mo, Na, Pb, Rb, Se, Sb, Sr, V, Tl and Zn have been determined in the whole fruiting bodies, as well as separately in caps and stalks, of fly agaric collected from three geographically distant sites in northern part of Poland. The elements were determined using ICP-MS, ICP-OES, HG-AAS and CV-AAS, respectively. For elements such as Al, Ba, Cr, Fe, Ga, Mo, Mn, Pb, Sb, Sr, Tl, and V concentrations were similar in the caps and stalks, respectively, and for K, Zn, Ag, Ca, Cd, Cu, Hg, Mg, Rb and Se were greater in the caps, while for Co, Cs and Na in the stalks. For Ag, Al, Ba, Ca, Cd, Co, Cr, Cs, Fe, Ga, Hg, Mn, Mo, Pb, Rb, Sb, Sr, Tl and V concentration in the caps showed spatial variations (P<0.05), while for Cu, K, Mg, Na, Se and Zn was independent of the site. The elements such as K with median or mean in the caps between 37,000 and 43,000 microg/g.dm and Mg with 920 and 1,100 microg/g dm were most abundant. Next, within median values range from approximately 100 to 500 microg/g dm were such as Ca, Fe and Al, and in descending order they followed by Rb (100-400 microg/g dm); V, Na, Zn (50-200 microg/g dm); Cu, Mn (10-50 microg/g dm); Cd (10-20 microg/g dm); Se (5 microg/g dm); Ba (<1-3); Cr, Ag, Pb, Sr (<1-2 microg/g dm); Cs, Co, Hg (<1-1 microg/g dm); Ga (<0.5), Sb, Mo and Tl (<0.1 microg/g dm).

Abstract
A combination of non-polar and shape selective columns in a comprehensive two-dimensional GC (GCxGC) system consisting of DB-5MS and LC-50 as the 1st and 2nd dimension columns was used to separate 22 tetrachloronaphthalene isomers. These columns enabled separation of all possible isomers of tetraCN found in the technical chloronaphthalene Halowax formulations into 18 peaks covering 15 single separated isomers and 7 co-eluting in triplicate (1,2,4,6-/1,2,4,7-/1,2,5,7-tetraCN; nos. 33/34/37) and in pairs (1,2,3,7-/1,2,4,5-tetraCN; nos. 30/32 as well as 1,3,5,8-/1,3,6,8-tetraCN; nos. 43/45). Twelve isomers of tetraCN resolved as single compounds by the GC x GC system used were found in Halowax 1001, 1013, 1014 and 1099 as well as in Equi-Halowax mixture. Three other tetraCNs that could be also resolved as single compounds were not detected in these materials, while the remaining 7 tetraCNs, which co-eluted, waits a further separation. The majority of constituents of the tetraCN homologue group of the Halowax formulations are isomers such as 1,4,5,8- (no. 46), 1,2,5,8- (no. 38), 1,2,4,8-tetraCN (no. 35), co-eluting 1,3,5,8-tetraCN (no. 43 in a pair nos. 43/45) and also co-eluting 1,2,4,6-/1,2,4,7-/1,2,5,7-tetraCN (nos. 33/34/37). The less abundant by amongst of tetraCNs in these mixtures are 1,4,6,7- (no. 47) and 1,3,5,7-tetraCN (no. 42). The remaining seven isomers, i.e., 1,2,3,4- (no. 27), 1,2,3,5- (no. 28), 1,2,3,6- (no. 29), 1,2,5,6- (no. 36), 1,2,6,7- (no. 39), 1,2,6,8- (no. 40) and 1,2,7,8-tetraCN (no. 41) are usually minor by quantity, while 1,2,3,7-/1,2,4,5-tetraCN (nos. 30/32) are also minor, or one of them is absent. Three tetraCNs not found in the Halowax formulations are isomers such as 1,2,3,8-tetraCN (no. 31), 1,3,6,7-tetraCN (no. 44) and 2,3,6,7-tetraCN (no. 48).

Abstract
Total mercury content has been determined in the fruiting bodies of fly agaric (Amanita muscaria) and topsoil layer (0-10 cm) collected from 14 spatially distant sites across Poland. Mercury was measured by cold-vapor atomic absorption spectroscopy (CV-AAS) after nitric acid (mushrooms) or nitric acid and sulfuric acid (soil) digestion of the samples. The caps, depending on the site, contained total mercury at mean concentrations from 0.24+/-0.13 to 1.4+/-0.6 microg/g dm (median 0.19-1.4 microg/g dm), and stalks from 0.18+/-0.06 to 0.71+/-0.26 microg/g dm (median 0.18-0.67 microg/g dm). An overall-mean the total mercury content for 204 caps and stalks was, respectively, 0.73+/-0.55 (0.05-3.3 microg/g dm) and 0.43+/-0.33 (0.09-2.3 microg/g dm).

Abstract
Concentrations of Ag, Al, Ba, Ca, Cd, Co, Cu, Cr, Cs, Fe, Ga, Hg, K, Mg, Mn, Mo, Na, Ni, Pb, Rb, Se, Sb, Sr, V, Tl and Zn have been determined in the whole fruiting bodies as well as separately in caps and stalks of Poison Pax collected from three geographically distant sites across Poland. The elements were determined using ICP-MS, ICP-OES, HG-AAS and CV-AAS, respectively. Based on arithmetic mean and median values for Poison Pax specimens from the Lezno site the elements such as Ag, Co, Cr, Cs, Mn, Mo, K, Pb, Rb, Sb, Se, V and Tl occur at similar concentration both in the caps and stalks, while for Cd, Cu, Hg, Mg and Zn around two-fold greater concentrations were noted in caps than stalks (cap/stalk concentration quotient > 1). Cs, Cd, Ni and Rb occurred at much greater concentration in specimens collected from the Kłodzka Hollow in the Sudety Mountains when compared to the lowland site (Mann-Whitney U-test), and slightly greater values were noted also for Cr, Mo and Rb, while for Ca, Co, Mg and Mn were smaller The results provide useful environmental and biological baseline level of information for metallic elements of Poison Pax.

Abstract
Data are presented on total mercury content of Poison Pax from 14 sites across Poland. Mercury was measured by cold-vapor atomic absorption spectroscopy (CV-AAS) after nitric (mushrooms) and nitric/sulphuric (soil substrate) acid digestion of the samples. Both the caps, stalks and whole fruiting bodies of Poison Pax exhibited mercury at relatively small concentration and for all sites the median values ranged from 0.01 to 0.10 microg/g dm (the caps) and from 0.01 to 0.10 microg/g dm (the stalks). The arithmetic means of mercury for most of the sites surveyed ranged from 0.01 +/- 0.01 to 0.11 +/- 0.06 microg/g dm (the caps) and from 0.01 +/- 0.01 to 0.11 +/- 0.04 microg/g dm (the stalks). The cap to stalk mercury concentration quotient for 181 fruiting bodies of Poison Pax in this study was 1.4 +/- 0.5 with range from 0.4 to 5.4, and for the particular sites were from 0.6 +/- 0.2 to 2.5 +/- 1.2. The total mercury content of top soil (0-15 cm) layer for most of the sites was within a range from 0.02 +/- 0.01 to 0.05 +/- 0.04 microg/g dm, while from 0.06 +/- 0.02 to 0.07 +/- 0.04 microg/g dm were for two sites in the Tucholskie Forest, and 0.10 +/- 0.04 and 0.09 +/- 0.04 microg/g dm were for an area near the industrial town of Starachowice and for the Kłodzka Hollow in the Sudety Mountains, respectively. Both the caps, stalks or whole fruiting bodies of Poison Pax were characterized by a relatively small bioconcentration factor (BCF) value of mercury with a median value between 0.2 and 3.3, 0.2 and 2.2 and 0.3.

Abstract
Molecular descriptors from calculations at the level of Density Functional Theory (B3LYP/6-311++G**) were effectively applied in QSPR estimation of supercooled liquid vapour pressures (P(L)) for individual chloronaphthalene congeners. The estimated values of log P(L) varied from 1.05 Pa to 5.6 x 10(-5) Pa, depending on the number of chlorine substituents present in the molecule and the substitution pattern. Comparison of the five chemometrical methods of modelling (approaches) led to the final conclusion, that the use of relatively simple PLS combined with one of the variable pre-selection algorithms (UVE or GA) seems to be the optimal choice in such computational studies for persistent organic pollutants. The best GA-PLS model was characterized by the value of root mean square error of prediction RMSEP = 0.108 logarithmic Pascal units.

Abstract
Cadmium, lead, copper and zinc were quantified using a validated ICP/MS method in the tissues and organs of 82 specimens of red deer of different sexes and ages, which had been hunted at the Great Lakes Land region in the north-eastern of Poland in 2000-01. Copper and zinc occurred in liver, kidney and muscle tissue of red deer at concentrations of 6.4-29, 3.3-7.2 and 1.9-6.4, and of 19-43, 17-41 and 19-64 mg kg(-1), respectively, which are considered typical for the species, age and gender compared with values noted for some other wild and domestic ruminant species elsewhere. For cadmium and lead, the concentrations decreased in the order kidney > liver > muscle tissue, with overall means of 2.2, 0.19, and 0.10, 0.31, and 0.26, 0.22 mg kg(-1) wet weight, respectively. The cadmium content of the kidney of a proportion of red deer sampled exceeded the legal tolerance limits set in Poland. The means (but not individual animal data) obtained for cadmium in kidney and liver correlated (0.99) with the age of red deer. Also, the lead content of the muscle meat of red deer for many carcasses exceeded the legal limit, which was probably due to contamination from the fine dust particle remains from the lead bullets used.

Abstract
Androgenic and anti-androgenic compounds including p,p'-DDE, Diuron, Linuron, Fenarimol, Vinclozolin, 1-(3,4-dichlorophenyl) urea (DCPU), 1-(3,4-dichlorophenyl)-3-methylurea, (DCPMU), tributyltin (TBT) and triphenyltin (TPT) and their metabolites (DBT, MBT, DPT, MPT) as well as metallic elements (Ni, Cu, Zn, As, Cd, Pb, Co, Tl, Cr, Fe, Mn, Al, K, Mg, Na, Ca, Ba, Ti, Sn), PAHs (16 indicator compounds), DDTs and PCBs have been quantified in top layer (0-10 cm) of up to 37 surface sediment samples collected from several sites in costal zone of the Gulf of Gdańsk, an inland freshwater area of Brdyujście in Poland and the tidal flats of the Norderney Island, Wadden Sea in 2002-2003. These sites differed in the degree of anthropogenic activities, including chemical pollution and related impact on biota. Especially in sediments near shipyards, ship repair facilities, harbours, other industrial activities or close to municipal sewage treatment plant outlets butyltins, PAHs and some metallic elements were found at high concentrations. Diuron, Linuron and DCPMU were detected at a few sites, Fenarimol only once, while Vinclozolin and DCPU were not detected. DDT concentrations in the sediments from the Gdańsk and Gdynia region of the Gulf show a stepwise decrease following the ban for production and use, while diffusion of PCBs at some industrial sites seems to continue. Elevated PAH concentrations in sediments seem to be mainly due to pyrogenic and less to mixed pyrogenic and petrogenic sources, while for a few sites rather petrogenic sources dominated. The reference sites in the Norderney Island, Wadden Sea showed similar or slightly higher loads of DDTs, BTs, PAHs, PCBs and metallic elements when compared to sediments from the least contaminated sites in the coastal Gulf of Gdańsk area, while phenyltins were not detected at both spatially distant European areas.

Abstract
All 19 possible chlorophenol (CPh) and 12 chlorobenzene (CBz) congeners as potential impurities or additive were quantified in a relatively highly chlorinated type of technical chlorobiphenyl (CB) mixtures of Aroclor 1268, Chlorofen, Clophen T 64, Kanechlor 600, and Kanechlor 1000 using isotope dilution technique and HRGC/HRMS. The total CBzs content of Aroclor 1268, Chlorofen and Clophen T 64, Kanechlor 600, and Kanechlor 1000 was 0.039, 0.5, 230, 0.068, and 400 mg/g, respectively, while of CPhs was < 0.007, 0.48, 10, 0.093, and 0.98 microg/g. All 12 congeners of chlorobenzene could be quantified in all the formulations examined, but their proportions varied largely. It seems that stockpiles of technical chlorobiphenyl formulations and hazardous wastes containing CBs, both with added and/or by-side CBzs are also a somehow forgotten source of environmental contamination with those environmentally relevant compounds. No CPhs were found in Aroclor 1268 (< 7 ng/g). 2-MoCPh, 2,6-DiCPh, 3,5-DiCPh, 3,4,5-TrCPh, and 2,3,4,5,6-PeCPh were absent (< 1- < 20 ng/g) in Chlorofen and Clophen T 64, while other chlorophenol congeners were found at concentration from 7.4 to 130 and from 9.9 to 8,800 ng/g, respectively. Then, 3- and 4-chlorophenol, which co-eluted, were main contributors (88%) to the total CPhs content of Clophen T 64, while 2,3,4,6-TeCPh with 27% abundance was a major congener among CPhs in Chlorofen. Then, 2,4,6-TrCPh was the most abundant congener in Kanechlor 600, while 2,4,5-TrCPh was the most abundant congener in Kanechlor 1000.

Abstract
Halowax 1051 is the highest chlorinated technical chloronaphthalene mixture among seven known formulations of the Halowax series. Octa- and heptaCN homologue groups are the main CN constituents of Halowax 1051 with declared 90% and 10% contents, respectively. In this study, using an isotope dilution technique and HRGC/HRMS, octaCN and heptaCNs contents of six batches of Halowax 1051 were between 82-93% and 6.2-17%, respectively. Also mono- to hexaCNs were found in Halowax 1051, and their content more or less varied according to the batch; also, the abundance of a particular CN congeners varied. Tetra-, penta- and hexaCNs have been found in all six batches of Halowax 1051 examined, and their contents varied between 0.0024-0.77%, 0.031-0.22%, and 0.21-0.82%, respectively. TriCNs have been found in three of six batches, and mono- and diCNs in two of six batches with 0.0020-0.40, 0.0017-0.25 and 0.0012-0.34% for positive findings, respectively. 2,3-DiCN (no. 10), 1,8-diCN (no. 9) at < 0.0002 mg/g, 1,6,7-/2,3,6-triCNs (nos. 25/26), 1,3,8-triCN (no. 22) at < 0.0002 mg/g, 1,3,6,7-tetra (no. 44), 1,2,3,6-tetra- (no. 29), 1,2,7,8-tetraCN (no. 41) and 1,2,3,6,7,9-hexaCN (no. 70) at < 0.0005 mg/g have not been found in Halowax 1051.

Abstract
Chloronaphthalene (CN) congeners and homologue groups have been quantified in up to three batches of several types of technical CN formulations of the Halowax series (Halowax 1031, 1000, 1001, 1013, 1014 and 1099), to elucidate possible batch-to-batch compositional variations. Using isotope dilution and HRGC/HRMS a relatively large variation in CN congeners and homologues composition among the batches of particular types of the Halowax formulations could be noted, and also when compared to the composition declared by the manufacturer. Depending on the type of the Halowax formulation and its batch in total up to 54 peaks from chloronaphthalenes (Agilent Ultra 2 liquid phase), which represented 70 of 75 CN congeners theoretically possible, could be found in these mixtures. These congeners represented all CN homologue groups from mono- to octaCN but some co-eluted. A co-eluting congeners were such as: 1,4-/1,6- (nos. 5/7), 1,5-/2,7- (nos. 6/12), 2,6-1,7- (nos. 11/8) of diCNs; 1,3,6-/1,3,5- (nos. 20/19), 1,3,7-/1,4,6- (nos. 23/24), 1,6,7-/2,3,6- (nos. 25/26) of triCNs; 1,2,5,7-/1,2,4,6-/1,2,4,7- (nos. 37/33/34), 1,3,6,8-/1,2,5,6- (nos. 45/36), 1,2,3,5-/1,3,5,8- (nos. 28/43), 1,2,3,4-/1,2,3,7- (nos. 27/30), 1,2,5,8-/1,2,6,8- (nos. 38/40) of tetraCNs; 1,2,3,5,7-/1,2,4,6,7- (nos. 52/60), 1,2,3,5,8-/1,2,3,6,8- (nos. 53/55) of pentaCNs; 1,2,3,4,6,7-/1,2,3,5,6,7- (nos. 66/67), 1,2,3,4,5,7-/1,2,3,5,6,8- (64/68) and 1,2,4,5,6,8-/1,2,4,5,7,8- (nos. 71/72) of hexaCNs. Absent in the Halowaxes were CN congeners such as 1,3,8-triCN (no. 22) (<0.0002 mg/g), 1,3,6,7-tetraCN (no. 44), 1,2,3,6-TetraCN (no. 29), 1,2,3,6,7-pentaCN (no. 54) and 1,2,3,6,7,8-hexaCN (no. 70) (<0.0005 mg/g).

Abstract
One hundred twenty five congeners of CDF off 135 theoretically possible were quantified in seven of various type Halowax formulations but still 45 co-eluted under the gas chromatographic conditions applied. The total CDFs concentration of Halowax formulations was between 250 and 16,000 ng/g. The compositional profile of CDF homologue groups of the Halowaxes frequently followed a degree of chlorination of the parent chloronaphthalene mixture and an exception was Halowax 1031. The compositional profile of many isomers of trichlorodibenzofuran, found and often highly abundant, was characteristic to majority of the formulations examined, and each of them demonstrated to have its own pattern but mysterious to explain remained Halowax 1031. In term of dioxin-like toxicity the most potent due to CDFs content was Halowax 1014 with 210 ng TCDD TEQ/g and next was Halowax 1013 with 36 ng TEQ/g, while between 1.3 and 5.0 ng TEQ/g were for other formulations. A tentative estimation made implies that the net total CDFs production due to manufacture of the technical CNs in the XX century could reach an amount between 420 kg (median) and 825 kg (mean), and for most toxic dioxin-like congeners between 705 g (median) and 5700 g (mean) TCDD TEQ, while for the worst case of Halowax 1014 alone scenario it could be 750 kg of the total CDFs and 16 kg of TCDD TEQ for most toxic congeners.

Abstract
Aroclor 1268, Chlorofen, and Clophen T 64 technical chlorobiphenyl formulations were examined for 75 congeners of chlorodibenzo-p-dioxin (CDD) and 135 congeners of chlorodibenzofuran (CDF) using isotope dilution technique, separation, and enrichment on silica gel impregnated with activated carbon and final high resolution gas chromatography (HRGC)/high resolution mass spectrometry (HRMS) quantification. Three the most highly chlorinated congeners of CDD were found in Aroclor 1268, Chlorofen, and Clophen T 64. In the case of CDF, the number of congeners identified was 108 with 44 coeluting in pairs and 3 in triplicate in Aroclor 1268, 16 with 4 coeluting in pairs in Chlorofen, and 88 with 46 coeluting in pairs and 3 in triplicate in Clophen T 64. The total CDD and CDF concentrations of Aroclor 1268, Chlorofen, and Clophen T 64 were 24, 160, and 8.5 ng/g and 1600,270,000, and 4000 ng/g, respectively. No mono- to hexa-CDDs could be quantified in Aroclor 1268 (<0.03 to <1 ng/g), Chlorofen (<0.07 to <0.3 ng/g), or Clophen T 64 (<0.007 to <2 ng/g), whereas two hepta-CDDs and octa-CDD were found in all three formulations, and Chlorofen was richer in those compounds, followed by Aroclor 1268 and Clophen T 64.

Abstract
A by-side chlorodibenzo-p-dioxins (CDDs) has been identified as impurity in concentration between 1.5 and 370 ng/g in the Halowax formulations of all type. Halowax 1014 was relatively richer in number of CDD congeners detected when compared to six other CN formulations examined. Amongst the mono- to tri-CDDs, the most prevalent in the Halowaxes were 1- and 2-MoCDD, and especially they were abundant in the formulations of a lower than a higher degree of chlorination. Amongst the tetra- to octaCDD only 1,2,3,4-/1,2,4,6-/1,2,4,9-/ 1,2,3,8-TeCDD, 1,2,3,4,6,7,8-HpCDD and OcCDD were found in all the Halowaxes, and 1,2,3,4,6,7,9-HpCDD remained undetected only in Halowax 1099 and 1013, while most of TeCDDs, PeCDD, and HxCDDs were absent in a majority of the formulations examined. The compositional profile of 1,2,3,4-/1,2,4,6-/1,2,4,9,-/1,2,3,8-TeCDD and OcCDD congeners found in the Halowaxes seem to indicate, that after an initial in situ formation of mono- and di-CDDs during CNs synthesis, a further increase of reaction time, temperature, and pressure can lead to successive chlorination of the already established chlorodibenzo-p-dioxin molecule, and so to enrichment in 1,2,3,4-/ 1,2,4,6-/1,2,4,9,-/1,2,3,8-TeCDD but also OcCDD content for most of the final products obtained. Nevertheless, also due to the co-synthesis of chlorophenols in the Halowaxes, their condensation reactions could also contribute to the formation of CDDs. In term of dioxin-like toxicity the most potent due to CDDs content was Halowax 1014 with 0.95 ng TCDD TEQ/g, and between 0.00068 and 0.058 ng/g were for other formulations. A rough estimation made implies that a net CDDs production due to manufacture of the technical CNs in the XX century could reach an amount between 3.0 and 12.6 kg, while for most toxic dioxin-like constituents between 5.25 and 24 g TCDD TEQ, For the worst case scenario and involvement of Halowax 1014 only the net total CDDs production was estimated to be 1.5 kg, and for highly-toxic congeners 71 g TCDD TEQ. All these figures are much lower when compared to co-production of CDFs.

Abstract
Chlorobiphenyl (CB) and by-side chlorodibenzofuran (CDF), chlorodibenzo-p-dioxin (CDD), and chloronaphthalene (CN) homologue group and congener composition, and concentrations have been examined in technical CBs mixture Clophen A60. 101 peaks representing 116 CB congeners were quantified in Clophen A60, and most contributing were CBs nos. 138, 153,134/144/149, and 180 with 15.4, 12.3,8.2, and 6.5%, respectively. Di-, tri-, tetra-, penta-, hexa-, hepta-, and octa-CBs constituted, respectively, 0.03, 0.03, 0.32, 9.9, 52.7, and 4.9% of chlorobiphenyls content of the Clophen A60, while mono-, nona-, and decaCB were not quantified. Tetra- to octaCDDs were absent in Clophen A60 at concentration above the method limit of quantification of <0.01 microg/g, while the total CDFs and CNs were found at 12 and 42 microg/g, respectively. Tetra-, penta-, hexa-, and hepta-CDF with 27, 46, 19, and 7% contribution, respectively, dominated in homologue group profile of CDFs, while octa-CDF was absent in Clophen A60. In compositional profile of CDF congeners the most abundant were 1,2,4,7,8-PeCDF, 2,3,4,7,8-PeCDF, and 1,2,3,4,7,8-HxCDF and each had >5% contribution. Amongst the CN homologue groups the profile in descending order followed by hepta-, hexa-, octa-, and penta-CNs with 56, 26, 16, and 2%, respectively. In compositional profile of CNs the most abundant were the congeners such as 1,2,3,4,5,6,7-HpCN (no. 73), 1,2,3,4,6,7-/1,2,3,5,6,7-HxCN (nos. 66/67), and 1,2,3,4,5,6,7,8-OcCN (no. 75) with 55, 21, and 16%, respectively. In terms of dioxin-like toxicity of Clophen A60 the contribution from planar non-ortho and mono-ortho CBs, CDFs, and CNs was 5280, 594.5, and 33.1 ng TCDD TEQ/g, respectively, and the total TEQ of planar analogues was 5908 ng/g.

Abstract
Computational n-octanol/water partition coefficients data for 75 chloronaphthalene congeners based on the Ghose, Pritchet, and Crippen algorithm; the Moriguchi method; and two QSPR models with principal component regression and partial least-squares (PLS) regression calculations are presented. Chloronaphthalenes log Kow data obtained after PLS are characterized by the lowest root mean square error (RMSEP = 0.0190), whereas results from the Ghose, Pritchet, and Crippen algorithm are characterized by the worst predictive ability (RMSEP = 0.4191). Minimal values of log Kow of chloronaphthalenes ranged between 3.57 and 3.90 for 1-chloronaphthalene, whereas maximal values ranged between 6.36 and 7.19 for octachloronaphthalene.

Abstract
All 209 chlorobiphenyls (CBs) theoretically possible and potentially present in relatively highly chlorinated types of technical CB formulations of Aroclor 1268, Chlorofen, Clophen T 64, KC-600, and KC-1000 have been quantified using isotope dilution techniques and high-resolution gas chromatography/high-resolution mass spectrometry (HRGC/HRMS). CB constituents of Aroclor 1268, Chlorofen, Clophen T 64, KC-600, and KC-1000 could be separated, detected, identified and quantified as "bulk CBs," using a capillary column (60 m length x 0.25 mm i.d.) coated by 8% phenyl polycarborane-siloxane (HT-8PCB, SGE, Australia) liquid phase for GC coupled to HRMS, into 111, 78, 126, 137, and 148 peaks, respectively, which covered 140, 100, 158, 169, and 180 possible CB congeners. 87, 60, 99, 110, and 121 peaks represented single CB congeners in Aroclor 1268, Chlorofen, Clophen T 64, KC-600, and KC-1000, respectively, while 34, 18, 27, 27, and 27 peaks represented 53, 40, 59, 59, and 59 co-eluting CBs. After enrichment procedures using multilayer silica beds, alumina beds, and carbon-impregnated silica beds in glass columns, all four planar non-ortho CBs and all eight mono-ortho CBs (but with the exception of CB no. 123 in Chlorofen) could be quantified in all five technical CB formulations examined. The planar non- and mono-ortho CBs content of Aroclor 1268, Chlorofen, Clophen T 64, KC-600 and KC-1000 were 6.2, 7.0, 47, 120, 470 mu g/g and 220, 410, 34,000, 12,000, 5900 mu g/g, respectively, and their 2,3,7,8-tetrachlorodibenzo-p-dioxin toxicity equivalents (2,3,7,8-TeCDD TEQs) were 31, 390, 710, 260, 1900 ng-TEQ/g and 35, 99, 5900, 2600, 8900 ng-TEQ/g, and the total 2,3,7,8-TeCDD TEQs of planar CBs were 66, 490, 6600, 2900, and 11,000 ng-TEQ/g.

Abstract
All seven Halowax formulations examined were contaminated with chlorophenols (CPhs). The total CPhs content of the CN mixtures ranged from 1050 to 34,200 ng/g. The absolute concentration of CPhs decreased with an increase of degree of chlorination (% Cl) of the Halowax 1031 (27%), 1000 (35%), 1001 (49%), and 1099 (51%), respectively, but remained relatively constant for higher chlorinated Halowax 1099 (51%), 1013 (54%), 1014 (59%), and 1051 (70%). 2,4,6-TrCPh and 2,4-DiCPh did contaminated all seven Halowax formulations and PeCPh remained undetected (<90 ng/g) only in Halowax 1099, while less frequently occurred 2,6-DiCPh and followed by 3-/4-MoCPh, 2,5-DiCPh, 2-MoCPh, 2,3-DiCPh, and 2,3,4,6-TeCPh. The CPh congeners such as 3,4-DiCPh, 3,5-DiCPh, 2,3,4-TrCPh, 2,3,5-TrCPh, 2,3,6-TrCPh, 2,4,5-TrCPh, 3,4,5-TrCPh, 2,3,4,5-TeCPh, and 2,3,5,6-TeCPh were undetected in any of the Halowax formulation examined. The profile (%) of higher chlorinated CPh homologues like PeCPh in the Halowaxes followed somehow a degree of chlorination (Cl %) of the parent mixture, i.e., increased from 14, 22, 43, 55, 52 to 80%, respectively, but exception was free of PeCPh the Halowax 1099. And contrary, for a lower chlorinated DiCPhs and TrCPhs their relative proportions decreased but again an exception was Halowax 1099. The fingerprint profiles of 2,4,6-TrCPh, 2,4-DiCPh, and PeCPh, which were usually the most abundant congeners varied and were less consisted when compared to the CPh homologue group profiles, and also more depended on the type of technical Halowax mixture. Due to absence of 2,4,5-TrCPh but presence of 2,4-DiCPh, 2,6-DiCPh, 2,4,6-TrCPh, and PeCPh, which, respectively, are indicative congeners for CPhs obtained by alkaline hydrolysis of chlorobenzenes or phenol chlorination using gaseous chlorine, just co-occurrence of phenol impurity in technical naphthalene is suggested as a solely source of CPhs in the Halowax mixtures.

Abstract
202 congeners of chlorobiphenyl (CB) with 109 single-resolved compounds and 93 co-eluting, which represented from mono- to deca-CB were quantified as by-side impurities in all seven and of various type the technical chloronaphthalene (CN) formulations of the Halowax series. IUPAC No. 104, 145, 159, 169, 184, 186, and 188 were undetected (<0.05-<0.7 ng/g). The total CBs content of the Halowax formulations ranged between 220 and 640,000 ng/g, and lower chlorinated Halowaxes 1031 (27% Cl) and 1000 (35% Cl) were two to three orders of magnitude more contaminated with CBs than higher chlorinated Halowax 1001, 1099, 1013, 1014, and 1051 (49-70% Cl). The profile of CB homologue groups of the Halowaxes changed and followed somehow a degree of chlorination of the parent CN mixture. For Halowax 1031 and 1000, a decreasing trend in proportion from mono- to deca-CB was evident, while for Halowax 1001, 1099, 1013, 1014, and 1051 the relative proportions between the CB homologue groups varied somehow. Evidently content of lower chlorinated mono- and di-CBs highly decreased and steadily increased tri- to octa-CBs and they become dominating homologues in Halowax formulations in parallel with an increase of the content of higher molecular weight CN constituents, respectively. Among planar non- and mono-ortho CBs, total concentrations in Halowax formulations were detected in the range of 2.0-2600 ng/g, and only 3,3',4,4',5,5'-HxCB (no. 169) was undetected (<0.05ng/g). Detection of by-side CBs in technical Halowaxes demonstrate clearly that those formulations apart from a massive introduction of dioxin-like CNs become in the past also an early source of environmental pollution with CBs, which proceeded for around 20-30 years use of original CB formulations.

Abstract
Non- and mono-ortho CBs as well as also highly toxic by-side impurities such as chlorodibenzofurans, chlorodibenzo-p-dioxins, and chloronaphthalenes after a subsequent 2D-HPLC and HRGC-HRMS separation, detection, and identification were quantified in technical chlorobiphenyl Chlorofen formulation. Chlorofen is highly chlorinated CB mixture and its compositional profile of mono-ortho CBs is occupied by 2,3,3',4,4',5'-HxCB (no. 157) with 96.6% and followed by 2,3,3',4,4',5-HxCB (no. 156) with 3.3% and 2,3',4,4',5,5'-HxCB (no. 167) with <0.1%, while nos. 105, 114, 118, 123, and 189 remained undetected (<10 microg/g). Amongst non-ortho CBs only a trace of 3,3',4,4'-TeCB (no. 77) was found at 15 microg/g, while CBs nos. 81, 126, and 169 were absent. TCDD TEQ for mono- and non-ortho CBs in Chlorofen was 2320 and 1.5 ng/g, respectively, while for CDFs and CNs were 45 and 731 ng/g, respectively, and for both types of contaminants most contributing were OcCDF and OcCN. No tetra- to OcCDD was found in Chlorofen.

Abstract
The concentrations of 63 congeners of chloronaphthalene (CN; polychlorinated naphthalenes, PCNs) in dated on approximately 500 B.C. to 2000 sediment core from the Lake Kitaura in Japan have been quantified by HRGC/HRMS after double column HPLC fractionation. Sediment from the Lake Kitaura showed a time-dependent pattern in distribution of CNs since the approximately 500 B.C. Starting from the 1910s the total CNs content increased accelerating from the 1960s, and, in parallel, the pattern of CN congeners has changed with a substantial increase in contribution from the penta, hexa, hepta, and octaCN. The total CNs content normalized to dry weight of sediment peaked out in the layer dated on 1984-1985, and next nearly two-fold decreased with further gradually decreasing concentration in 1987-2000. An occurrence of tri and tetraCNs in deep sediment layers corresponded to preindustrial synthesis and use of CNs seems to be connected to relatively greater water solubility and mobility in the pore water of those CN homologue groups. Based on CN congener pattern and results of multivariate analysis three main layers were separated in the sediment core. Starting from 1981 the emission sources related to combustion marker congeners become substantial contributors to flux of annually deposited CNs, while relative significance of the evaporative source marker congeners decreased after 1985. The annual flux of CNs into sediments of the Lake Kitaura was 0.073-0.31 pg/cm2 before 1926, increased to 5.5-14 pg/cm2 in 1963-1970 and next sharply increased to 50-107 pg/ cm2 in 1971-1985, and after that decreased to 17 pg/cm2 in 1997-2000.

Abstract
Total chlorobenzene content of the Halowax mixtures ranged from 1100 to 9800 ng/g. A lower chlorinated Halowax 1031 and 1000 were a several times more contaminated with chlorobenzenes than higher chlorinated Halowax 1001, 1099, 1013, 1014, or 1051. Depending on the type of the Halowax mixture the most contributing amongst of chlorobenzene homologue groups were di-, tetra-, penta-, and hexa-CBz. A dominance and specific profile of 1,4-DiCBz, PeCBz, and HCBz were characteristic to Halowax 1001, 1099, 1013, 1014, and 1051, while for other formulation the CBzs profile varied, and 1,2,3,4-TeCBz (Halowax 1031) and 1,4-DiCBz (Halowax 1000) predominated. A steric hindrance effect seems to direct a preferential by-side formation of 1,4-DiCBz and further also of PeCBz and HCBz due to relatively elevated temperature as well as duration time of synthesis for five most chlorinated (49-70 Cl%) chloronaphthalene Halowax formulations.

Abstract
Chloronaphthalenes are dioxin-like environmental and food contaminants that for many years have undergone diffusion from dispersed emission sources of various types on a global scale. When released into ambient air like many other semivolatile organohalogen compounds, chloronaphthalenes undergo various processes and pathways including sequestering by plant vegetation and biota. Recently available data indicate that sequestering rates of chloronaphthalenes by plant biomass and including edible plants as well as concentrations in food sources of plant origin can be greater than was earlier predicted. Additionally, it become known very recently that in some highly industrialized countries such as Japan, Canada and the UK, the technical chloronaphthalene mixtures are still a subject of industrial and commercial interest, even if such activities are illegal. Recent achievements in HRGC-HRMS have enabled elucidation and quantification of the chloronaphthalene congener composition in environmental matrices, food sources and technical mixtures, their persistency, environmental fate, accumulation in biota and potential for food chain biomagnification. However, at the same time this raised questions regarding human exposure to these compounds. By the late 1990s, these developments added to the relatively rapidly growing knowledge on these compounds and especially individual congener properties such as thermodynamic and physicochemical features and toxicity. Multistage fractionation has recently enabled routine congener-specific quantification of tetra- to octachloronaphthalene in various matrices. This paper reviews the literature on chloronaphthalenes as food chain contaminants and covers their origin, physicochemical properties, toxicity, environmental concentrations and persistency, and homologue group and congener composition in various matrices. The review also covers distribution in environmental compartments and subsequent fate and migration to food sources, as well as the magnitude of dietary intake and human body concentrations. Data on chloronaphthalene residues in food, however, are still scare, an exception being seafood sources and recently available data from Spain on their concentrations in staple foods and dietary intake.

Abstract
A follow-up case study was performed after two incidents of recent illegal import and use in Japan both of technical PCNs mixture and contaminated with those compounds an industrial raw material. In case 1, above 18 tons of PCNs mixture, resembling Halowax 1001, which is a technical PCNs formulation, were imported from the United Kingdom. An illegally imported PCNs mixture was used for manufacture of a wide spectrum of industrial materials and commercial goods including sealants, putty, shock absorbing materials, adhesive materials, insulating materials and rubber belts. About 1.3 tons of PCNs contained in the Neoprene FB manufactured reached domestic market and 9.3 tons could reach other markets. In case 2, which became known in 2001, the Japanese company imported from Canada 54 tons of PCNs contaminated raw rubber material for industrial use. In weathering test (40 degrees C for up to 168 h) of the feral rubber coated sheets for rubber bands 98% of di- and 66% of tri-CNs vaporized. A loss rate of tetra-, penta-, and hexa-CN during initial 12 h of the weathering test ranged from approximately 10 to approximately 20%, while from 12 to 168 h remained negligible.

Abstract
The aim of the work was to determine the 210Po content in phytobenthos species (seaweeds and angiosperms) from Puck Bay (southern Baltic). Alpha spectrometry was used to measure and calculate the activities and concentrations of polonium 210Po in the phytobenthos. The activity of 210Po in Puck Bay waters was determined to estimate the bioconcentration factors (BCF) of these plants. The 210Po concentration in water was estimated at 0.25 mBq dm(-3). The lowest polonium concentration in the phytobenthos was found in Cladophora rupestris (0.12 Bq kg(-1) wet wt.), the highest in Chara crinita (1.12 Bq kg(-1) wet wt.). Polonium is accumulated in these phytobenthos species; the bioconcentration factors (BCF) ranged from 450 to 4400.

Abstract
Mercury (Hg) was quantified using cold vapour-atomic absorption spectrometry (CV-AAS) in the fruiting bodies of nine edible and five inedible mushrooms and in underlying soil substrate samples. In total, 404 samples comprising caps and stalks and 202 samples of soil substrate (0-10 cm layer) were collected in 1996 from Trójmiejski Landscape Park, northern Poland. Mean Hg concentrations in the soil substrate for different species varied between 10 +/- 3 and 780 +/- 500 ng x g(-1) dry wt (range 2.3-1700). Among edible mushroom species, Horse Mushroom (Agaricus arvensis), Brown Birch Scaber Stalk (Leccinum scabrum), Parasol Mushroom (Macrolepiota procera), King Bolete (Boletus edulis) and Yellow-cracking Bolete (Xerocomus subtomentosus) contained elevated concentrations of Hg ranging from 1600 +/- 930 to 6800 +/- 4000 ng x g(-1) dry wt in the caps. Concentrations of Hg in the stalks were 2.6 +/- 1.1 to 1.7 +/- 1.0 times lower than those in the caps. Some mushroom species investigated had high Hg levels when compared with specimens collected from the background reference sites elsewhere (located far away from the big cities) in northern Poland. Bioconcentration factors of Hg in the caps of Horse Mushroom, Parasol Mushroom and Brown Birch Scaber Stalk were between 150 +/- 58 and 230 +/- 150 ng x g(-1) dry wt, respectively, and for inedible Pestle-shaged Puffball (Claviata excipulformis) was 960 +/- 300 ng x g(-1) dry wt. Linear regression coefficients between Hg in caps and in stalks and Hg soil concentrations showed a positive relationship for A. arvensis and Horse mushroom (p < 0.05) and a negative correlation for the caps of Death Caps (Amanita phalloides) and Woolly Milk Cap (Lactarius torminosus) (p < 0.05), while for other species no clear trend was found.
