By using gas-liquid chromatography the content of organic mercury compounds (methyl- and ethyl derivatives) in some widely consumed in alimentation fish species and marine products was determined. Methyl mercury was found in 96.2 per cent of a total of 104 samples. The average level of its content in the fish species under study was dissimilar, viz. in cod fish--0.045 + .0053 mg/kg. in sea perch--0.021 +/- 0.0029 mg/kg; in sprat--0.0050 +/- 0.0013 mg/kg. In marine products (crustacea, sea crayfish, shrimps) the percentage of the methyl mercury detection comprised 100, 60 and 85, respectively and the contamination level did not exceed 0.0520 mg/kg. Ethyl mercury was found in 33--35 per cent of 40 samples of shrimps and crustacea and in 13.6 per cent of fish subjected to analysis. From the above data the amount of methyl mercury introduced with a diurnal portion of fish was estamated at 0.9--5.0 psi per man-day.
