Metal bioaccessibility of soils in urban parks in Fredericton and Saint John, New Brunswick
Abstract
The purpose of this research was to determine the concentrations and bioaccessibility of metals in urban playground soils in the province of New Brunswick. Ten parks each were selected for sampling in Fredericton and Saint John, and a duplicate sample was taken from one park in each city. Metal bioaccessibility was determined by an in vitro physiologically based extraction test (PBET). The risk associated with exposure to selected metals (including As, Ba, Cd, Co, Cu, Pb, Ni and Zn) in soil from the urban parks in New Brunswick studied was fairly low based on the total metals concentrations and bioaccessibility data obtained in this study.
