Bioaccumulation in freshwater crabs, Endosulfan accumulation in different tissues of Zilchiopsis collastinensis P. (Decapoda: Trichodactylidae)
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 en...

| Sumario: | 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. |
