摘要: 目的:探讨淮河水蚌埠段有机污染物对小鼠遗传毒性和脂质过氧化作用的影响。方法:用淮河蚌埠段上、下游水、出厂水及末梢水的有机提取物分别做小鼠微核试验、精子畸形试验,并进行脂质过氧化物(L PO) 、超氧化物歧化酶(SOD) 及谷胱甘肽过氧化物酶( GSH2Px) 检测。结果:淮河不同区段水质有机提取物均有不同程度的致突变性;与对照组相比,血清、肝、脑组织L PO 水平增加( P < 0. 05~0. 01) ,SOD 和GSH2Px 活性降低( P < 0. 05~0. 01) 结论:淮河N 段水有机污染物有潜在的遗传毒性,并能影响小鼠的脂质过氧化作用。

Abstract: Purpose : To investigate the effect s of organic chemical pollutant s in water f rom Bengbu (N) section of Huai river on mouse gentoxicity and lipid peroxidation. Methods : Organic chemical concent rates of water were taken f rom the lower and the upper N sections of Huai River , the water works , and the dist ribution network ,respectively , and the mouse micronucleus test , sperm deformity test were used to detect their gentoxicity. Lipid peroxides (L PO) , superoxide dismutase (SOD) and glutathione peroxidase ( GSH2Px) were also determined. Results : The positive mutagenicity to a certain degree was induced by the organic chemical concent rates of the water samples ( P < 0. 05~0. 01) , high levels of L PO and lower activities of SOD and GSH2Px were found. Conclusion : Organic chemical pollutant s of the water in the N section of Huai River have potential genotoxicity and influence on mouse lipid peroxidation.

Key words: water pollution, organic chemicals concent rate, genotoxicity, lipid peroxidation.
