The Use of Earthworm Ecotoxicological Test in Risk Assessment of Soil Contamination

Earthworm is one of the most important biological indicators of soil quality. Earthworm ecotoxicology has made rapid progress in the past years, and a number of test methods and approaches have been developed. The authors provided an overview of established or standardized earthworm tests, including toxicity test, survey of population dynamics, avoidance test, bioaccumulation test and biomarker test, and gave a brief introduction to their application in monitoring and risk assessment of soil contamination. Moreover, the prospect and future development of earthworm ecotoxicology were discussed.
