Abstract

Objectives: This study was performed to determine environmental hazard factors and provide more eco-friendly child activity spaces within children's playgrounds installed in Gyeonggi-do Province. Methods: Basic (XRF) and precise (ICP, UV) inspections were conducted. The test items examined were heavy metals and parasite eggs. As a sampling point, painted finish materials (180), synthetic rubber (50), and sand (50) were selected. Results: The total excess rate of heavy metals in the XRF was found to be 7.4% (17/230 points). In a comparison between the basic and precise inspections with 17 excess points, the concentration deviation between the two tests was found to be from 0.01 to 7.7 times, resulting in a large difference. Furthermore, all the excess samples were dual samples. However, the contribution rates of Pb and $Cr^{6+}$ to combined concentration were found to be 85.1 and 14.9% for basic inspection and 91.9 and 8.1% for precise inspections, so there is a similar tendency between the two tests. The excess rate of parasite eggs in sand was expressed at 6%. The excess rate of heavy metals in synthetic rubber was found to be 0%. Conclusion: The reliability of the XRF is low. However, considering the contribution rate of Pb and $Cr^{6+}$ between the two tests, it is likely to be applicable for screening. Dual samples provided high concentrations and excess samples and care should be taken when managing them.
