Biochemical responses of earthworm Eisenia fetida exposed to cadmium-contaminated soil with long duration.
Bull Environ Contam Toxicol. 2012 Dec; 89(6):1148-53.BE

Abstract

The biochemical responses of the earthworms, Eisenia fetida, exposed to a series of Cd concentrations (0.00, 1.25, 2.50, 5.00 and 10.00 mg Cd(2+) kg(-1) soil) for up to 8 weeks were investigated, aiming to evaluate the sublethal effects of Cd with long exposure and to explore the potential for applying these responses as biomarkers to indicate the Cd-contaminated soil. The following biochemical parameters were determined: cytochrome P450 (CYP) contents and activities of superoxide dismutase (SOD), catalase (CAT) and glutathione-s-transferase (GST). Cadmium concentrations in all earthworms were apparently accumulated in 4 weeks, and showed minor changes in weeks 6-8 compared to the first 4 weeks. CYP presented a significant elevation in 2-4 weeks and a decline in 6-8 weeks in each treated group. The activities of SOD and CAT showed an obvious increase with exposure of 6-8 weeks while their levels were not affected in 4 weeks in each treated group. GST activity revealed significant activation starting from week 4. This study confirmed the significance of applying a suite of biomarkers rather than a selective choice to assess the impact of pollutants on organisms. It also indicated that the observed effects were more dependent upon exposure duration than dose.
