초록
This study was performed to perceive environmental pollution in children's playground in Gwangju metropolitan city. Two types of sand and synthetic rubber as flooring material were used in children's playground. The sampling was collected from 20 sites in sand flooring material and 21 sites in synthetic rubber flooring material. They are measured to evaluate pH, heavy metals, and parasite eggs in sites of sand flooring material and also to heavy metals in sites of synthetic rubber floor material. In site of sand flooring material, pH range was from 5.8 to 8.8. The average concentration of Pb, As, Hg, Cd, and Cr6+ was 16.318, 0.343, 0.048,0.258, and 0.000 in unit mg/kg, respectively. In site of synthetic rubber flooring material. The average value of the total sum concentration of heavy metals such as Pb, As, Hg, Cd, and Cr6+ was 70.427 mg/kg. This total concentration of heavy metals was even much lower than that of criteria (1,000 mg/kg). The parasite eggs were not found in sites of sand flooring material. Therefore, it showed that all sites in children's playground was safe environmentally.
