HCHs, DDTs, and PCBs were analyzed in fish flesh collected from fish ponds in the Pearl River Delta and compared with those from the Mai Po Marshes (a nature reserve) in Hong Kong, which was considered an unpolluted area. The concentrations for these contaminants were <0.01-7.8 ng/g lipid for HCHs, 22.3-381 ng/g lipid for DDTs, and 60-480 ng/g lipid for PCBs. Nevertheless, levels of HCHs and DDTs in fish flesh were lower than the China National Environmental Protection Agency maximum permissible limits set for foodstuffs. As for PCBs, 16% of fish collected from the Pearl River Delta exceeded the US EPA guideline concentration.
对从珠江三角洲鱼塘采集的鱼肉中的六氯环己烷、滴滴涕和多氯联苯进行了分析，并与香港米埔沼泽（一个自然保护区，被视为未受污染地区）的鱼肉进行了比较。这些污染物的浓度分别为：六氯环己烷<0.01 - 7.8纳克/克脂质，滴滴涕22.3 - 381纳克/克脂质，多氯联苯60 - 480纳克/克脂质。然而，鱼肉中六氯环己烷和滴滴涕的含量低于中国国家环境保护局规定的食品最大允许限量。至于多氯联苯，从珠江三角洲采集的鱼中有16%超过了美国环境保护局的指导浓度。
