Effects of chronic polybrominated diphenyl ether exposure on gonadal development in the northern leopard frog, Rana pipiens.

abstract：:Pulp and paper mill effluents have been linked to effects on fish reproduction for more than 25 years. To date, the causes of these effects and remedial strategies have eluded investigators. Recent work has shown that the degree of reproductive effect caused by a mill effluent is related to the overall organic content...
