| Abstract: | Because amphibians are relatively resistant to organophosphorus insecticides and can bioaccumulate residues to high levels, they may be a source of secondary poisoning for vertebrates that feed on them. This hypothesis was tested by determining residues in breeding upland chorus frogs Pseudacris triseriata, that were collected from ponds treated with the organophosphorus insecticide fenthion. Frogs were collected up to 3-days posttreatment in four areas that were treated with fenthion formulated in either diesel oil or water. No residues of fenthion were detected above the 0.01 ppm level of analytical sensitivity. These results indicate that the frogs were not a likely source of secondary poisoning for predatory vertebrates. |
