When I compared the organic chemicals copper sulfate and pyrethrum to the top synthetics , chlorpyrifos and chlorothalonil , I found that not only were the organic ones more acutely toxic , studies have found that they are more chronically toxic as well , and have higher negative impacts on non-target species .
Children who were exposed prenatally to the insecticide chlorpyrifos had significantly poorer mental and motor deelopment by three years of age and increased risk for behaior problems , according to a peer-reiewed study published today by the american academy of pediatrics in its journal , pediatrics .
