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 .

当我把有机农药中的硫酸铜与除虫菊和主要合成农药毒死蜱与百菌清做了比较以后，我发现有机农药不但急性毒性更强，研究还发现它们的慢性毒性也更强，而且对非目标种有更大的不良影响。

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 .
