Arsenic Picked Up from the Playground
Detail: Several nations today ban or severely restrict the use of wood preserved with chromated copper arsenate (CCA), but many existing structures still remain--for example, about 70% of existing U.S. single-family homes and 14% of public playgrounds incorporate CCA-treated wood. In recent years, scientists have studied how arsenic leaches from CCA-treated wood, but they have only inferred exposure levels from measurements of arsenic concentrations in soil and sand near treated wood structures. Elena Kwon of the University of Alberta and colleagues report on direct measurements they made of arsenic on the hands of children playing in playgrounds, some with CCA-treated wood structures and others without [EHP 112:1375-1380]. The team reports that although playing on treated structures increases the amount of arsenic on children's hands, washing the children's hands after playing may be enough to avoid the health risks associated with CCA.
