Sixty soil samples collected from 20 parks and playgrounds were analyzed for pH, total metal concentration by X-ray fluorescence. In addition, in vitro bioaccessibility assay (IVBA) was conducted for seven of the samples. The pH values of all soil samples were within the Canadian Council of Ministers of Environment (CCME) soil quality guidelines for residential/parkland use. The mean metal concentrations were below the CCME guidelines; however, a few samples had metal concentrations exceeding the guidelines. These included barium (1), cadmium (1), chromium (1), and nickel (3). The metal IVBA values ranged from 9.5% to 79.6%. Based on metal concentrations and the IVBA, the human health risk associated with the ingestion of metals in soils in the parks and playgrounds sampled was deemed low.
