In a survey sponsored by the Ministry of Food Agriculture and Forestry of the Federal Republic of Germany the mercury contamination of 759 specimens of fishes from the German fishing grounds were analysed. The determinations were performed by flameless atomic absorption (cold vapour system). -We found for the fishes of greatest economic importance herring, cod, saithe, haddock very low averages of less than 0,1 ppm. The legal limit of 1 ppm was only reached or exceeded by older fishes (ling 1.18 ppm, red-fish 1.09 ppm) and by specific kinds of fishes (shark 3.23 ppm, ray 1.69 ppm, tuna 0.80 ppm). -The organically bound mercury (methyl-Hg) which is considered especially toxic, has been determined by gas-liquid-chromatography. Methyl-Hg constitutes about 70--98% of the total mercury, a value which is in agreement with Japanese and Swedish reports on this subject.
在德意志联邦共和国粮食、农业和林业部发起的一项调查中，对来自德国渔场的759份鱼类样本的汞污染情况进行了分析。测定采用无火焰原子吸收法（冷蒸气系统）。——我们发现，具有最大经济重要性的鱼类，如鲱鱼、鳕鱼、黑线鳕、黑线鳕，平均汞含量非常低，低于0.1 ppm。只有较老的鱼类（海鳗1.18 ppm、红鱼1.09 ppm）和特定种类的鱼类（鲨鱼3.23 ppm、鳐鱼1.69 ppm、金枪鱼0.80 ppm）达到或超过了1 ppm的法定限值。——通过气液色谱法测定了被认为具有特别毒性的有机汞（甲基汞）。甲基汞约占总汞的70 - 98%，这一数值与日本和瑞典关于该主题的报告一致。
