Roxarsone is a normal used feed additive in animal breeding. Its ecotoxicological effect has been noticed in recent years. However, very few studies have concerned its effect on the enzymatic activities in earthworms. In present study, we investigated the activities of catalase (CAT), acetylcholine esterase (T-CHE), as well as the content of MDA in earthworms exposed to roxarsone. 5 different concentration groups of roxarsone were designed to simulate the process that roxarsone was discharged into soil with animal manure. CAT, MDA and T-CHE in worms were respectively measured in different time after exposure. The results showed that CAT in worms was activated by roxarsone. This activation was dose-dependent to some extent. The content of MDA was almost unchanged during the treatment either in low or in high dose group. T-CHE could be inhibited by roxarsone. This inhibition was more obvious in the high dose level groups than the low ones. As a conclusion, CAT and T-CHE might be used as biomarker of roxarsone contamination in soils.
