We examined the bioaccumulation of α- and β-endosulfan and endosulfan sulfate in tissues from the crab Zilchiopsis collastinensis. There was more endosulfan accumulated in the hepatopancreas (from <2 to 467.8 ng g(-1)) than in the gonads (from <2 to 52.1 ng g(-1)) or muscles (<2 ng g(-1)). The endosulfan concentrations in the hepatopancreas decreased over time and with the endosulfan dilution (p < 0.05). In the gonads there was little bioaccumulation, which did not vary over time (p > 0.05). The hepatopancreas is a dynamic organ that is able to depurate itself, whereas the gonads act as a sink for pesticides.
我们研究了螃蟹 Zilchiopsis collastinensis 组织中α-和β-硫丹及硫丹硫酸酯的生物累积情况。肝胰腺中积累的硫丹（<2 至 467.8ng/g）多于性腺（<2 至 52.1ng/g）或肌肉组织（<2ng/g）。肝胰腺中的硫丹浓度随时间推移和硫丹稀释而降低（p<0.05）。性腺中几乎没有生物累积，且其浓度随时间推移无明显变化（p>0.05）。肝胰腺是一个能够自我净化的活跃器官，而性腺则是杀虫剂的汇。
