Objective To study the mutagenicity of water from Yangling-Xingping section of Weihe River and wastewater from paper mills along the river. Methods No1 and No2 paper mill as the pollution source were located along the Yangling-Xingping section of Weihe River,their sampling points were named paper mill 1 and paper mill 2.The outlets for sewage at the bank of Weihe River in Yangling and Xingping were selected the sampling points of pollution sections, namely Yangwu and Xingwu respectively. The clear sections (Yangshang and Xingshang) were situated at a distance of 1 km from polluted sections at the upper reaches of Weihe River were selected and at the sames at the lower reaches were selected as the self-purification sections, namely Yangxia and Xingxia. The mutagenicity of water samples collected from above sampling points was tested by Ames test,mouse sperm malformation test, Vicia faba root tips cell micronucleus test. Results The results of Ames test showed that the water samples of Xingwu, Xingxia and two paper mills presented mutigenicity.The water samples of Xingwu, Xingxia and two paper mills showed significantly higher levels of sperm malformation rates compared with that of negative control group(P
