Soil Metal Distribution in Parks and Playgrounds in Select Municipalities in Metro Vancouver

This study was conducted to identify the soil metal profile in parks and playgrounds in select municipalities in Metro Vancouver that have been rapidly developing during the past few years. Sixty-eight soil samples were analyzed for metals including As, Cd, Cr, Cu, Fe, Ni, Pb, Sn, U, V, and Zn by X-Ray Florescence and assessed against the Canadian Council of Ministers of the Environment (CCME) soil quality guidelines (SQG) for residential/parkland use. In vitro bioaccessibility analyses were also conducted to determine the human health risk associated with ingestion of metals present in the soil samples. Metal concentrations and the bioaccessibility results suggested that the human health risk associated with accidental ingestion of contaminated soils at parks and playgrounds where samples were collected was minimal. For Ba, which exceeded the CCME SQG, with moderate bioaccessibility, may suggest a potential risk to human health.
