Study: Arsenic Not a Playground Concern

EDMONTON, Alberta, May 24 (UPI) — Canadian researchers say arsenic in playground structures may be nothing to worry about.

University of Alberta researchers say their findings did not support a popular idea that playing on chromated copper arsenate-treated wood playground structures was a threat to children’s health.


Chris Le and colleagues analyzed arsenic levels in urine and saliva samples of children who play in eight pressure treated wooden playgrounds, as well as of children playing in eight playgrounds made of other materials. The researchers found no significant differences in concentration of arsenic in the children.

The study, published in Environmental Science & Technology, suggested contact with chromated copper arsenate-treated wood in playgrounds is not likely to contribute significantly to the overall arsenic exposure in children.
