Effect of Environmental Contaminant on Rana nigromaculata Based on Environmental Materials
Abstract:
Environmental materials are widely used, which destroy the environment. We used Rana nigromaculata to research the effects of environmental material dicofol. Rana nigromaculata were injected in ventral lymph follicle in different doses of dicofol solution every a day. After the treatment, the sperm activation, sperm deformity, number and abnormal ratio were observed and calculated. The results show that with the dicofol concentration increasing, sperm activation reduces, sperm number decreases, sperm abnormality rate increases significantly. The conclusion is that dicofol has toxic effects on R. nigromaculata reproduction obviously.
