Descrição: It seems important to examine heavy metal concentration in playgrounds, to evaluate potential risk for heavy metal ingestion by children. In this study, heavy metal concentrations of soil samples in 40 playgrounds in K-city were investigated by the voltammetric method. To visualize heavy metal concentration distribution in playgrounds, free GIS software MANDARA was used. According to the comparison between the 1 N HCl dissolved concentration and the PTWI (Provisional Tolerable Weekly Intake), playgrounds in K-city may not have intake risk of lead. Even if the possibility of the risk was very low, there are differences of the intensities. As for the specific playground where concentration is high, investigating continuously may be desirable hereafter.
