Studies on the Mouse Sperm Mlaformation Affected By water from Main Streams of Weihe River and Paper Mills

目的 研究渭河干流及造纸厂对小鼠精子的致畸性。方法 采用小鼠精子畸形实验方法 ,结果 杨上、杨下、杨污、兴上各点水样的精子畸形率分别为 5 9.6‰、5 3.0‰、4 3.0‰和 6 2 .0‰ ,与阴性对照相比差异不显著 ;而兴下、兴污、1号纸厂和 2号纸厂各水样的精子畸形率分别为 6 7.3‰、82 .0‰、10 1.0‰和 84 .0‰ ,与阴性对照相比差异显著。结论 兴下、兴污、1号纸厂和 2号纸厂各水样对小鼠精子具有显著的致畸作用 。

objective To studies the hereditary toxicity of Main Streams of Weihe River and Paper Mills.Method Means of sperm malformation test in mouse is used in this article.Result The results show that malofrmation rate of sapmles of Yangshang,Yangxia,Yangwu and Xing wu shang is59.6‰?53.0‰?43.0‰ and 62.0‰,malformation rate of samples of Xingxia,xingwu,No.1 paper mill No.2 paper mill is 67.3‰?82.0‰?101.0‰and 84.0‰ Conclusion Samples of xingxia,xingwu,No.1 and No.2 paper mill have mouse sperm malformation funciton and potential dangerous to human.
