Abstract

The content of chlorinated fat-soluble aromatic hydrocarbons was determined in fish from an area polluted by industrial effluents. The fish species investigated were selected among those used for human consumption. For some samples, both the fillet and liver were investigated. For others the whole fish was used. The following compounds were analysed and quantified: Trichlorobenzene, tetrachlorobenzene, pentachlorobenzene, hexachlorobenzene, heptachlorostyrene, octachlorostyrene and polychlorinated biphenyls. The results idicate an appreciable accumulation in fish of the higher chlorinated compounds as pentachlorobenzene, hexachlorobenzene, heptachlorostyrene and octachlorostyrene. Other chlorinated hydrocarbons as decachlorobiphenyl, pentachloronaphthalene, hexachloronaphthalene and hexachlorostyrene were identified, but not quantified. The total content of fat-soluble chlorine was determined in some samples before and after sulphuric acid treatment. The content of chlorine in the identified and quantified compounds accounted for between 40 and 100 per cent of the total amount of chlorine present in the samples as persistent (sulphuric acid resistant) compounds.

摘要

对来自一个受工业废水污染地区的鱼类中氯化脂溶性芳烃的含量进行了测定。所调查的鱼类品种是从供人类食用的鱼类中挑选出来的。对于一些样本，对鱼片和肝脏都进行了调查。对于其他样本，则使用整条鱼。分析并定量了以下化合物：三氯苯、四氯苯、五氯苯、六氯苯、七氯苯乙烯、八氯苯乙烯和多氯联苯。结果表明，在鱼类中，五氯苯、六氯苯、七氯苯乙烯和八氯苯乙烯等高氯化化合物有明显的积累。还鉴定出了其他氯化烃，如十氯联苯、五氯萘、六氯萘和六氯苯乙烯，但未进行定量。在一些样本中，测定了硫酸处理前后脂溶性氯的总含量。已鉴定和定量的化合物中的氯含量占样本中作为持久性（耐硫酸）化合物存在的氯总量的40%至100%。
