Abstract
Sulfonamides are one of the oldest groups of veterinary chemotherapeutic agents. Physico-chemical properties, the concentration and the nature of the environment are the factors responsible for the distribution of sulfonamides in the living organism. Although these drug compounds have been in use for more than half a century, knowledge about their behavior is still limited. Physiological activity is currently attributed to the sulfanyl radical. Our study is devoted to the spectral properties of aqueous solutions of sulfaguanidine, in which the formation of complexes with an H-bond and a protonated form takes place. The nature of the fluorescent state of sulfaguanidine was interpreted using computational chemistry, the electronic absorption method and the luminescence method. The structure of sulfaguanidine includes several active fragments: aniline, sulfonic and guanidine. To reveal the role of fragments in the physiological activity of the studied antibiotic, we calculated and compared the effective charges of the fragments of aniline and sulfaguanidine molecules. Chromophore groups were identified in molecules, which determine the intermolecular interaction between a molecule and a proton-donor solvent. The study also revealed the impact of sulfone and guanidine groups, as well as complexation, on the effective charge of the antibiotic fragment responsible for physiological activity and luminescent ability.

Abstract
Apart from numerous applications, for example in azo dye precursors, explosives, and industrial processes, the nitro group (-NO2 ) appears on countless molecules in photochemical research owing to its unique characteristics such as a strong electron-withdrawing ability and facile conversion to the reduced substituent. Although it is well known as a fluorescence quencher, fluorescent chromophores that contain the nitro group have also emerged, with 3-nitrophenothiazine being recently reported to have 100 % emission quantum yield in nonpolar solvents. The diverse characters of nitro-containing chromophores motivated us to systematically review those chromophores with nitro substituents, their associated photophysical properties, and applications. In this Review, we succinctly elaborate the advance of the fluorescent nitro chromophores in fields of intramolecular charge transfer, fluorescent probes and nonlinear properties. Special attention is paid to the rationalization of the associated emission spectroscopy, so that the readers can gain insights into the structure-photophysics relationship and hence gain insights for the strategic design of nitro chromophores.

Abstract
Tests of crude oil toxicity to fish are often chronic, exposing embryos from fertilization to hatch to oil solutions prepared using standard mixing procedures. However, during oil spills, fish are not often exposed for long periods and the dynamic nature of the ocean is not easily replicated in the lab. Our objective was to determine if brief exposures of Atlantic herring (Clupea harengus) embryos to dispersed oil prepared by standard mixing procedures was as toxic as oil dispersed in a more realistic model system. Embryos were first exposed to chemically dispersed Alaska North Slope crude and Arabian light crude oil for 2.4 h to 14 d from fertilization to determine if exposure time affected toxicity. Toxicity increased with exposure time, but 2.4-h exposures at realistic concentrations of oil induced blue-sac disease and reduced the percentage of normal embryos at hatch; there was little difference in toxicity between the two oils. Secondly, oil was chemically dispersed in a wave tank to determine if the resultant oil solutions were as toxic to herring embryos as laboratory-derived dispersed oil using a single exposure period of 24 h. Samples taken 15 min postdispersion were more toxic than laboratory-prepared solutions, but samples taken at 5, 30, and 60 min postdispersion were less toxic. Overall, the laboratory- and wave tank-derived solutions of dispersed oil provided similar estimates of toxicity despite differences in the methods for preparing test solutions, suggesting that laboratory and wave tank data are a reliable basis for ecological risk assessments of spilled oil.

Abstract
Abstract
The fate of the sulphonamide drug, sulphasomizole, in man, dog, rabbit and rat has been studied. In man, rat and rabbit, the major urinary metabolite, is N4-acetylsulphasomizole together with the unchanged drug. In man about 60 per cent of an oral dose of 30 mg./kg. is excreted in the urine in 24 hr., just over a third being acetylated. In the rabbit about 80 per cent of an oral dose (150 mg./kg. is excreted in 24 hr. and about two-thirds is acetylated. In the rat about 70 per cent of the dose (150 mg./kg.) is excreted in 24 hr. and just under one third is acetylated. In the dog, the main excretory product is the unchanged drug, there being no acetylation. All four species excrete small amounts (1 per cent) of the N4-glucuronide of sulphasomizole. Other minor metabolites detected were the N4-sulphate of sulphasomizole which was found in rat and dog urine, and an unidentified oxidation product present as a glucuronide which was detected in rabbit and dog urine.

Abstract
The use of various organic compounds in solution and inorganic ions in glasses has been investigated as possible fluorescence Standard Reference Materials. Emphasis was placed on measuring physical and chemical parameters such as stability, reproducibilities of absorbance and fluorescence measurements, relative quantum efficiencies as a function of excitation wavelength, etc., for quinine derivatives and selected organic compounds. A brief discussion is included on the use of rare earth and non-rare earth inorganic ions in glasses as standards.

Abstract
1. The variations in the excitation and fluorescence wavelengths and fluorescence intensities of a number of indole and aniline derivatives over a wide range of acidity and alkalinity (36n-sulphuric acid to 10n-potassium hydroxide) have been studied. 2. The changes in fluorescence with pH of the indoles and anilines had many characteristics in common, and the most fluorescent species were found to be the non-ionized or neutral forms showing fluorescence maxima at about lambda 350mmu. 3. In 10n-potassium hydroxide most of the compounds examined, except those containing a tertiary nitrogen atom, showed a bathochromic shift in fluorescence wavelength attributable to an anion due to a negatively charged nitrogen, but in strong acid (3n-sulphuric acid) these compounds were non-fluorescent, except the anisidines and the 5-hydroxyindoles. 4. p-Anisidine but not the o- and m-isomers showed excited-state ionization in acid solution. 5. Of the hydroxyindoles only the 5-hydroxy derivatives showed a fluorescence (lambda(max.) 520-540mmu) in acid solution. It is suggested that this fluorescence is due to a proton-transfer reaction in the excited state, and various arguments for this suggestion are given. 6. Stokes shifts for the various ionic and neutral species of the indoles and anilines have been calculated, and the large shifts found with indole and p-anisidine may be due to solvent-solute interaction.

Abstract
1. The variations with pH (from 36n-sulphuric acid to 10n-sodium hydroxide) of the excitation and fluorescence wavelengths and fluorescence intensity of 2-, 3- and 4-hydroxypyridine and their O- and N-methyl derivatives were investigated. 2. 4-Hydroxy- and 4-methoxy-pyridine were non-fluorescent at all pH values. 3. The cations and dipolar ions of the 3-hydroxypyridine derivatives and the anion of 3-hydroxypyridine were fluorescent, but the neutral forms were not. 4. All the forms of the 2-hydroxypyridine derivatives were fluorescent. 5. Pyridoxol, pyridoxal and its 5-phosphate, pyridoxamine and pyridoxic acid and its lactone were studied similarly. All these compounds, except pyridoxal 5-phosphate, were more fluorescent than 3-hydroxypyridine. 6. The most fluorescent forms of these compounds are the anions, except for pyridoxol, where the dipolar ion was the most fluorescent form. The least fluorescent forms are the neutral molecules. The dipolar ions were appreciably fluorescent in all cases. 7. The most fluorescent form examined was the dianion of pyridoxic acid lactone. 8. The cations were all fluorescent except the cations of 2- and 3-methoxypyridine. All the cations showed excited-state ionization. The excited pK(a) values of these cations were determined and the results are discussed with reference to Weller's (1952) equation relating ground- and excited-state dissociation constants. 9. The pK(a) values for all ionizations undergone by the compounds examined were determined from fluorescence data. 10. Stokes shifts for the various ionic and neutral species of the compounds examined were calculated and are discussed.

Abstract
1. The variation with pH of the excitation and fluorescence wavelengths and fluorescence intensity of several hydroxy- and amino-biphenyls has been investigated with a view to using the data for the determination of hydroxybiphenyls in biological material. 2. 2- and 3-Hydroxy-, 2,2'-dihydroxy-, and 2-, 3- and 4-amino-biphenyl exhibited excited-state ionization. 4-Hydroxy- and 4,4'-dihydroxybiphenyl did not, and showed normal fluorescence changes with pH. 3. Biphenyl and 2- and 4-methoxybiphenyl showed no changes in fluorescence in the range pH0-14. 4. 4,4'-Dihydroxybiphenyl showed fluorescent peaks corresponding to the un-ionized form, the monoanion and dianion at the appropriate pH values, but 2,2'-dihydroxybiphenyl showed fluorescent peaks corresponding to the un-ionized form and the monoanion only, suggesting that it did not form a dianion. 5. 3- and 4-Nitrobiphenyl were non-fluorescent. 6. These results are discussed.
