Abstract：Using artificial soil test, physiological activities in earthworms (Eisenia foetida), which included superoxide dismutase (SOD, Cu-Zn SOD), catalase (CAT) and gulathione-S-transferase (GST), and other biochemical activities, such as GSH and MDA, exposed to dioxin-like PCBs at the levels of 0.1, 1, 10, 100, 1000μg/kg, were observed after 2, 7, 14 and 28d exposure. Dioxin-like PCBs could significantly increase SOD, Cu-Zn SOD, CAT, GST activities and GSH and MDA levels (P<0.05), and induce starting of antioxidant systems in the earthworms. The relationships results showed that the best response times of various physiological activities in earthworms to dioxin-like PCBs were different. The best response time of Cu-Zn SOD activities was 7 days, whereas that of GST activities was 28 days. The best response times of others physiological activities were all 14 days. During the best response times, there were significantly dose-response relationships between the dioxin-like concentrations logarithms and physiological activities logarithms (P<0.001).
