Resumen:
We examined the bioaccumulation of a- and b-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.
