Abstract: Purpose and Methods : To test the pollution of Sushui River in Wenxi County and the wells along the river using the root tip cells micronucleus test of V icia f aba and garlic. Results : V icia f aba test showed that e water samples taken f rom five places in the River were polluted by genotoxicant s , the order of the pollution severity in turn being Dongqiao , Luzhuang reservoir , Diantou , Suncun and Sucun. The garlic test showed thesimilar result s and a high positive correlation compared with the result s of V icia f aba ( r = 0. 9503 , P < 0. 01)As for the well water , V icia f aba test showed that four out of the five wells near the bank. and two of the five wells distant f rom the bank were polluted. The result s of garlic test indicated that two wells near the bank and one well distant f rom the bank were polluted ; which also showed a positive correlation with the result s of Vicia f aba test ( r = 0. 8790 , P < 0. 025 ) . Conclusion : this study suggested that the river and some of the wells along the river were polluted in a different degree ; garlic as a new method could be used in the study of genotoxity Key words : Pollution of Sushui River ; Wells along the river , Genotoxicity , Micronucleis test .
