Earthworms might be a good bioindicator for the contamination of roxarsone to soil. No significant influence of roxarsone contamination upon the biomass and the reproductive ability of earthworms was found, which indicated that earthworms could tolerate heavy contamination of roxarsone. 2. Effects on the important enzymatic system of earthworms The activities of PROD, BROD and MROD in P450 family were inhibited.
