摘　　要：The response of the superoxide dismutase （SOD） activities of earthworm （Eisenia fetida） to soil plumbum （Pb） pol ution was studied in the artificial soil test. The results indicated that the SOD activity in earthworm exposed to low-concentra-tion Pb declined on the 5th day of acute toxicity test, while that exposed to high-concentration Pb increased by different extents. On the 15th day, the SOD activity increased slightly along with soil Pb concentration increasing.该研究采用人工土壤试验法,检测在不同Pb浓度土壤中赤子爱胜蚓(Eisenia fetida)SOD酶活性变化。结果表明,染毒第5天时,受到低浓度Pb胁迫的蚯蚓体内SOD活性降低,而受到高浓度Pb胁迫的蚯蚓体内SOD活性不同程度的升高。染毒第15天时,蚯蚓体内SOD活性随土壤中Pb浓度的增大而升高。
