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.
通过气液色谱法测定了一些在饮食中广泛食用的鱼类和海产品中有机汞化合物(甲基和乙基衍生物)的含量。在总共104个样本中,96.2%的样本检测出甲基汞。所研究鱼类中其含量的平均水平各不相同,即:鳕鱼——0.045±0.0053毫克/千克;海鲈——0.021±0.0029毫克/千克;黍鲱——0.0050±0.0013毫克/千克。在海产品(甲壳类、海螯虾、虾)中,甲基汞的检出率分别为100%、60%和85%,且污染水平不超过0.0520毫克/千克。在40个虾类和甲壳类样本中有33% - 35%检测出乙基汞,在接受分析的鱼类中有13.6%检测出乙基汞。根据上述数据,估计每人每天从日常食用的鱼类中摄入的甲基汞量为0.9 - 5.0微克。
