Concentrations of polychlorobiphenyls (PCBs), hexachlorocyclohexane isomers (HCHs), DDT compounds (DDTs), hexachlorobenzene (HCB), aldrin, dieldrin, heptachlor and heptachlor epoxide were determined in foodstuffs collected from different locations in Vietnam. Elevated levels of PCBs, DDTs, HCHs, and aldrin and dieldrin were found in animal fat, butter, meat, and seafood. Caviar and butter samples imported from the Soviet Union contained considerably higher amounts of PCBs, HCHs and DDTs. The average daily intake of some organochlorines by Vietnamese people were higher than those observed in most of the developed nations. The dietary intake of DDTs was the highest among various chemicals studied. Interestingly, the daily dietary intake of PCBs was comparable to those in developed countries. Fish, shellfish, prawn, and crab were the primary route of DDTs to humans, whereas cereals and vegetables were the predominant sources of PCBs and HCHs.
对从越南不同地点采集的食品中多氯联苯（PCBs）、六氯环己烷异构体（HCHs）、滴滴涕化合物（DDTs）、六氯苯（HCB）、艾氏剂、狄氏剂、七氯和环氧七氯的浓度进行了测定。在动物脂肪、黄油、肉类和海鲜中发现多氯联苯、滴滴涕、六氯环己烷以及艾氏剂和狄氏剂的含量升高。从苏联进口的鱼子酱和黄油样本中多氯联苯、六氯环己烷和滴滴涕的含量要高得多。越南人某些有机氯的日均摄入量高于大多数发达国家。在所研究的各种化学物质中，滴滴涕的膳食摄入量最高。有趣的是，多氯联苯的每日膳食摄入量与发达国家相当。鱼类、贝类、对虾和螃蟹是滴滴涕进入人体的主要途径，而谷物和蔬菜是多氯联苯和六氯环己烷的主要来源。
