Ecotoxicity of Chromium (III) to Eisenia fetida, Enchytraeus albidus, and Folsomia candida

摘要

Despite growing concerns about the potential adverse effects of elevated chromium concentrations in the environment, only a few terrestrial toxicity data are available. Therefore, chronic toxicity of chromium(III) was assessed for Eisenia fetida, Enchytraeus albidus, and Folsomia candida, the three invertebrates for which standard test protocols are available. The 21-day EC_(50) for the cocoon production of E. fetida was 892 (679-1110) mg Cr/kg dry weight. Based on the reproduction, a 42-days EC_(50) of 637 (355-791) mg Cr/kg dry weight was observed for E. albidus, while for F. candida a 28-day EC_(50) of 604 (254-3380) mg Cr/kg dry weight was noted.
