HERBICIDE EFFECTS ON FISH REPRODUCTION : ENDOCRINE DISRUPTION CAPABILITIES OF SURFLAN AND ORYZALIN

This report describes research initiated in response to concerns regarding the potential endocrine disruption capabilities of herbicides used by the California Dept. of Transportation (Caltrans) in their roadside maintenance program. After testing several herbicides, the product Surflan with the active ingredient oryzalin was selected for analysis. The report discusses the investigations looking at the reproductive toxicity of the herbicide to male and female Japanese medaka. The mechanistic indicators of toxicity of oryzalin are also examined. Results from the investigations demonstrate that the xenoestrogens Surflan and oryzalin have significant effects on the gonads and liver.
