This report presents results of a study to determine the transfer of three pesticide commonly used in residential lawn care from turf grass to human skin. Formulations of the insecticides chlorpyrifos and cyfluthrin and the fungicide chlorothalonil were applied to St. Augustine grass and allowed to dry for 4 and 24 hours. After 24 hours, adult volunteers performed hand presses (left and right hands, palm only) with either dry or wetted skin. The mean (six presses) transfer efficiencies for chlorpyrifos were 0.115% for water-wetted, 0.156% for saliva-wetted, and 0.046% for dry skin. Transfer efficiencies for the other two pesticides were much higher (3.06%, 2.72%, and 1.29% for chlorothalonil and 4.02%, 4.18%, and 2.93 for cyfluthrin, respectively), but the same relationship were observed; no essential differences between saliva- and water-wetted skin and substantially lower transfer efficiencies for dry skin.
