The micronucleus tests examined after 96 hours exposure of 3 different concentrations(1.0, 2.0, 3.0 ppm) of Methomyl and Butachlor, were studied in order to find out the risk of aquatic ecosystems due to the genotoxicity of pesticides. The results are summarized as follow: 1. The occurrence frequencies of micronucleus were slightly increased with dose- dependent response in methomyl experiments. 2. After exposure in common pesticides, erythrocytes were induced to cellular transformations: spherocytes, anisocytosis, echinocytes, vacuolation and haemolysis. 3. Nuclear abnormalities other than micronuclei were found such as notched nuclei, blebbed nuclei, diffused nuclear amterial and enucleated cells. Key words: Japanese Medaka (Oryzias latipes), pesticide, herbicide, micronucleus Bao-Quey Huang 黃寶貴 2005 學位論文 ; thesis 57 zh-TW
