Abstract
Radionuclide contamination in food is a public health issue. Bivalves are known to accumulate relatively high levels of radionuclides. Despite many relevant reports, this information is poorly organized. Therefore, in this study, we conducted a comprehensive scientific review of radionuclides in marine bivalves. In general, the accumulation of radionuclides in bivalves is highly species and tissue-specific, which may be due to the different biological half-life of radionuclides in different species and tissues. The trophic pathway is the main pathway for the accumulation of most radionuclides in bivalves, with polonium-210 (210Po) and lead-210 (210Pb) potentially selectively accumulating in the digestive glands, while 134Cs and 137Cs selectively accumulating in the adductor muscle and mantle. Some other radionuclides (radium-226 (226Ra) and strontium-90 (90Sr)) are absorbed along with other minerals (e.g. Calcium) and selectively accumulate in bivalve shells. The information in this study can provide an overview of radionuclide contamination in marine bivalves.

Abstract
In this work data of salinity, temperature, suspended particulate matter (SPM), chlorophyll-a, and phytoplankton concentration in the Gibraltar Strait coast, in the confluence of the Mediterranean Sean and the Atlantic Ocean, were analyzed together with 210Po, 40K, 210Pb and 234Th activity concentration in different types of bivalve molluscs at the same time-period. The physicochemical parameters were evaluated using the Copernicus Marine Environment Monitoring Service (CMEMS) products based on satellite observations. A multivariate statistical analysis, including contrasted natural radioactivity contents, allowed the discrimination of bivalve molluscs from Atlantic and Mediterranean coasts. Additionally, a cluster analysis determined a highly significant negative correlation 210Po concentration in molluscs and phytoplankton concentration suggesting that phytoplankton concentration in the water column is a determinant factor to regulate 210Po concentration in those animals. These results introduce a useful tool to calculate the radiological doses in seafood from chlorophyll satellite image.

Abstract
In this study, heavy metals (Cd, Co, Cu, Ni, Pb, Zn, V) and 210Pb analyses have been performed in the marine biota (scaldfish, sea lettuce, crab). Samples were collected from 5 different parts of the Marmara Sea and Western Black Sea in January 2020. The results indicated that the highest Cu and Zn content was found in algae samples, but it was observed that heavy metal concentrations such as Co, Cu, Cd and V were generally low and under permissible limit. Also, 210Pb (radioactive isotope of Pb) activity levels were determined to vary from 23.20 Bq kg-1 to 52.67 Bq kg-1 dry weight. It was clearly seen that there was a linear correlation between the toxic and radioactive Pb when the obtained data were compared.

Abstract
The activity concentrations of natural radionuclides (210Po and 210Pb) and residual pesticide levels were determined from the fish (red mullet, common sole, anchovy, horse mackerel, gray mullet, and sardine) and mussel samples collected in İzmir Bay seasonally from October 2012 and July 2013. The 210Po and 210Pb concentrations varied between 5.7 ± 4.0 Bq kg-1 dry weight (dw) to 353.7 ± 45.0 Bq kg-1(dw) and 0.7 ± 0.2 Bq kg-1 (dw) to 4.3 ± 0.8 Bq kg-1 (dw), respectively. From a public health point of view, the fish and mussel collected from the İzmir Bay are not harmful to consumers.

Abstract
Baseline levels of radionuclides in the marine environment of the Balearic Islands in Western Mediterranean have not been reported in literature. Because of their ecological role and acknowledged sensitivity to pollutants, herein, the activity concentrations of 210Po, 40K, 210Pb, 90Sr, and 234Th were measured in two types of benthic invertebrate species (mussels and sea urchins) sampled during 2012-2018. The activity concentrations of 210Po, 40K, 210Pb, and 234Th ranged from 38 ± 1 to 325 ± 11 Bq kg-1 dry weight (d.w.), 220 ± 10 to 996 ± 46 Bq kg-1 d.w., ND (lower than the limit of detection) to 55 ± 8 Bq kg-1 d.w., and ND to 70 ± 15 Bq kg-1 d.w., respectively. In all cases, no artificial 90Sr activity was detected in the collected samples. The committed effective dose to humans was calculated to be in the range of 48-640 μSv year-1.

Abstract
The presence of natural and artificial radionuclides in the marine environment produces the accumulation of radionuclides in bivalve molluscs consumed by humans, and therefore it could result in a radiological hazard. In this study, the activity concentrations of 210Po, 40K, 210Pb and 234Th were determined in different types of bivalve molluscs sampled during the period of May 2014-June 2015, along coastal areas from the Andalusian region (South of Spain), through alpha-particle spectrometry and low-level gamma-ray spectrometry. The activity concentrations of 210Po; 40K; 210Pb and 234Th varied between 40 ± 2 and 515 ± 9 Bq kg-1 dry weight (d.w.); 121 ± 7 and 674 ± 34 Bq kg-1 d.w.; ND (lower than limit of detection) and 73 ± 10 Bq kg-1 d.w.; and ND and 126 ± 27 Bq kg-1 d.w., respectively. The committed effective dose to humans was calculated to range from 41 to 479 μSv year-1. Both activity concentrations and dose levels were comparable to previous studies from other countries. Finally, a multivariate statistical analysis of natural radioactivity content allowed the discrimination between bivalve molluscs from Atlantic and Mediterranean coasts.

Abstract
It is well known that the marine organisms are used as biological indicators for environmental pollution studies. Among these studies, the research on oxidative stress has been increasing in recent years. In this study, mussels (Mytilus galloprovincialis) and fish (Solea solea) samples were collected seasonally from İnciraltı, İzmir, Turkey. This station was in an area where fishing is carried out for human consumption. The relationship between 210Po and oxidative stress markers (lipid peroxidation (LPO), H2O2 and proline) was investigated in the mussel tissue (digestive gland, gills) and fish tissue (liver, gills) samples. The present study indicated that H2O2 accumulated with increasing 210Po concentration in mussel samples. Statistically significant correlation were found between H2O2 and 210Po and LPO and proline in mussel samples. This correlation between LPO and proline can be attributed to common environmental parameters (other than 210Po) affecting expression of both LPO and proline levels. There was not a significant correlation between 210Po and LPO levels. Similarly, a significant correlation was not found between 210Po and proline.

Abstract
The total activity of 210Po was determined by alpha-spectrometry in various samples (matrices) collected in the Gulf of Trieste (northern Adriatic Sea) where fresh water inflows, especially from the Isonzo River in the northern part, affect water quality. Observed 210Po levels were: 1) 0.56-3.75 mBq/L in the dissolved phase (<0.45 μm) in the seawater column and local rivers, 2) 0.35-3.11 mBq/L (400-2300 Bq/kg, dry weight, dw) in suspended particulate matter (SPM, 0.45-20 μm) in the seawater column and local rivers, 3) 40 (Isonzo River) -158 Bq/kg (in a surface sediment cores collected in a NS transect in the gulf and sectioned to the depth of 20 cm) and 4) 239 (autumn) - 415 to 1800 (spring) Bq/kg (dw) in meso(zoo)plankton (>200 μm). In seawater and tributaries, up to 80% (mean 49%) of total 210Po was found in particulate form. In sediments, slightly higher levels were encountered in the Isonzo prodelta and in the central (depocenter) part of the gulf. KD (L/kg) calculated between seawater and SPM, and seawater and sediment amounted to about 5 × 106 and 6 × 104, respectively. Lower autumn 210Po levels can be a consequence of biological dilution by higher mesozooplankton biomass in the autumn compared to spring. Plankton fractionation revealed in general the highest levels in the >200 μm mesoplankton fraction (239-1800 Bq/kg) followed by 50-200 μm (388-996 Bq/kg) and 20-50 μm (318-810 Bq/kg) microplankton fractions. Obtained data show higher 210Po levels in all matrices analyzed in the Gulf of Trieste compared to other Adriatic (central Adriatic) and western Mediterranean areas. The 210Po/210Pb ratios in water, plankton and sediments were mostly below or around 1, while this ratio was much higher at higher trophic levels (up to about 50), reflecting a preferential bioaccumulation of 210Po over 210Pb. 210Po accumulation between seawater and SPM and seawater and mesozooplankton amounted to 3.7 × 104 and 1.1 × 104, respectively, similar to other Adriatic areas. Comparison of the relative importance of pelagic and benthic bioaccumulation pathways, excluding the filter feeder bivalves, suggests greater accumulation in pelagic-feeding species.

Abstract
The activity concentration of 210Po in 26 species of marine macroalgae found along coast near to a nuclear installation in southeast coast of India was studied. Phaeophytes were found to accumulate the maximum 210Po concentration and chlorophytes the minimum. The average 210Po activity concentration values in the three groups were 6.2 ± 2.5 Bq kg-1 (Chlorophyta), 14.4 ± 5.2 Bq kg-1 (Phaeophyta) and 11.3 ± 3.9 Bq kg-1 (Rhodophyta). A statistically significant variation in accumulation was found between groups (p < 0.05). The un-weighted dose rate to these algae due to 210Po was calculated to be well below the benchmark dose limit of 10 μGy h-1.

Abstract
The Golden Horn is an estuary located in the center of İstanbul receiving freshwater discharges from two creeks and connecting to the Bosphorus Strait. Activity concentrations of natural and artificial radionuclides were determined in mussels (Mytilus galloprovincialis) and sediments from the Golden Horn sampled in February 2012. Mean activity concentrations of (137)Cs, (40)K, (226)Ra, (228)Ra, (210)Po and (210)Pb in the mussels were determined at 1.03±0.23, 389±41.6, 2.61±1.23, not detected (ND), 91.96±37.88 and 11.48±4.85 Bq kg(-1), respectively. In sediments, it was observed that (137)Cs, (40)K, (226)Ra, (228)Ra, (210)Po and (210)Pb activity concentrations in<63 μm particle fraction of sediment were generally higher than those determined in mussels. Po-210 and (210)Po/(210)Pb ratios in mussels from the Golden Horn were much lower than in mussels from other coastal regions and this was related to low plankton productivity and eutrophication of the Golden Horn.

Kılıç Ö, Belivermiş M, Cotuk Y, Topçuoğlu S. Radioactivity concentrations in mussel (Mytilus galloprovincialis) of Turkish Sea coast and contribution of ²¹⁰Po to the radiation dose. MARINE POLLUTION BULLETIN 2014; 80:325-329. [PMID: 24398417 DOI: 10.1016/j.marpolbul.2013.12.037] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/19/2013] [Revised: 12/10/2013] [Accepted: 12/14/2013] [Indexed: 06/03/2023]
Abstract
Radionuclides levels were determined in indigenous and transplanted mussels (Mytilus galloprovincialis) collected from Turkish marine environment. Radioactivity concentrations of ¹³⁷Cs, ⁴⁰K, ²²⁶Ra, ²²⁸Ra, ²¹⁰Po and ²¹⁰Pb were determined in the soft tissues of the mussel samples collected in Bosphorus Strait, Coasts of Black Sea, Marmara Sea and Aegean Sea. Mussel transplantation was carried out by using mussel cages in Levantine Sea coast since M. galloprovincialis did not naturally adapt along the coast. The average activity concentrations of ¹³⁷Cs, ⁴⁰K, ²²⁶Ra, ²²⁸Ra, ²¹⁰Po and ²¹⁰Pb in the coastline of Turkey were found to be 0.7±0.1, 469±24, 0.9±0.1, 1.0±0.1, 122±4 and 10.9±0.9 Bq kg⁻¹ in dry weight (dw), respectively. The average of ²¹⁰Po/²¹⁰Pb ratio was found to be ∼14. Total annual effective ²¹⁰Po dose was calculated to be in the range of 0.25-3.30 μSv due to mussel consumption. Radioactivity and dose levels were compared with those of similar studies carried out in Mediterranean countries.

MARINE POLLUTION BULLETIN 2013; 68:152-156. [PMID: 23260630 DOI: 10.1016/j.marpolbul.2012.11.044] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/26/2012] [Revised: 11/23/2012] [Accepted: 11/26/2012] [Indexed: 06/01/2023]
Abstract
In this study, the activity concentrations of (210)Po and (210)Pb were determined in mussels (Mytilus galloprovincialis) collected from Didim and Izmir Bay (Turkish coast of Aegean Sea) during the period of April 2006-March 2007. The concentrations activity of (210)Po were determined spectroscopically through its 5.30 MeV alpha particle emission, using (209)Po as an internal tracer. The (210)Pb activity concentrations were determined from the ingrowth of (210)Po, assuming zero initial (210)Po activity. The results of (210)Po and (210)Pb activity concentrations were found to vary between 34 ± 9 and 1855 ± 98 Bq kg(-1) dry weight and ND (lower than limit of detection) - 64 ± 6 Bq kg(-1) dry weight, respectively. (210)Po/(210)Pb ratio ranged between 1.00 and 106.87. The highest (210)Po activities were found in mussels collected from Didim.

THE SCIENCE OF THE TOTAL ENVIRONMENT 2012; 437:413-421. [PMID: 22964374 DOI: 10.1016/j.scitotenv.2012.07.089] [Citation(s) in RCA: 9] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/28/2012] [Revised: 07/18/2012] [Accepted: 07/27/2012] [Indexed: 06/01/2023]
Abstract
Deep-sea hydrothermal mussels Bathymodiolus azoricus live in the mixing zone where hydrothermal fluid mixes with bottom seawater, creating large gradients in the environmental conditions and are one of the most studied hydrothermal species as a model of adaptation to extreme conditions. Thiol proteins, i.e. proteins containing a thiol or sulfhydryl group (SH) play major roles in intracellular stress defense against reactive oxygen species (ROS) and are especially susceptible to oxidation. However, they are not particularly abundant, representing a small percentage of proteins in the total proteome and therefore are difficult to study by proteomic approaches. Activated thiol sepharose (ATS) was used for the rapid and quantitative selection of proteins comprising thiol- or disulfide-containing subproteomes. This study aims to isolate thiol-containing proteins from the gills of B. azoricus collected in distinct hydrothermal vents and to study the thiol-containing subproteome as a function of site-specific susceptibility to ROS. Results show that ATS is a powerful tool to isolate the thiol-containing sub-proteome and differently-expressed protein spots showed significant differences among the three vent sites, supporting previous findings that specific environmental conditions are crucial for ROS formation and that B. azoricus have different susceptibilities to oxidative stress depending on the vent site they inhabit.
