Abstract: Purpose and Methods: The study used micronucleus test in Vicia faba to detect and compare the genotoxicity of water samples collected from Panlong River and Dianchi area in Kunming City. Results: Except the sample from the SongHua Dam( the headwaters of Panlong River), all the water samples signifi cantly inducedmicronuclei in vicia faba (P < 0.001～0.01). The highest micronuc leus freauencies was induced by the sample No.6 which was collected in JinTaiTan Irrigation and Drainage station which takes abundant industrial and municipal waste water effluent. Conclusion: The results imply that the water samples from Panlong River and Dianchi lake contain some polluting component(s) which induced genetic damage.

Key words: Panlong river, Dianchi lake, micronu cleus
