%X The toxicity of the herbicide simazine to the survival and gonadal development of amphibian Xenopus laevis were determined and compared with the effects of atrazine. X. laevis were exposed to simazine or atrazine in water from Nieuwkoop and Faber (NF) stage 46/47 to one month postmetamorphosis. Followed by another two months without exposure, the gonads of frogs were examined in gross morphology and histology. During the exposure period, the growth and survival of frogs were recorded every day. Results showed that, at the first week of exposure, simazine induced higher mortality at stage 46~50, and had no effect on the survival in the following period but caused a lack of synchronicity in development stage. Atrazine had no toxicity to the survival and growth of X. laevis. Simazine as well as atrazine did not affect gross gonadal morphology and the sex ratio. However, simazine as well as atrazine induced histologic degeneration of testis to some degree. The results suggested that simazine as well as atrazine might have the potential to impair testicular development by feminizing/demasculinizing.
