Pesticide 'causes frogs to change sex'. A common weedkiller is blamed for global decline of amphibians after lab tests suggest it seems to cause male frogs to change sex.

If atrazine is causing a problem, there should be a coorelation between the number of female frogs and the concentration of atrazine in each area. 12:48:21 PM
