Abstract

The pollution status of heavy metals in the soils of children's playground was investigated for a sustainable soil environment in urban parks of Seoul. As sampling sites, 281 locations were selected from a 7 districts in the Seoul city. The overall mean concentrations of the heavy metals (Cd 0.21 mg/kg, Cu 5.97 mg/kg, As 2.40 mg/kg, Pb 7.55 mg/kg, Zn 34.08 mg/kg, Ni 4.22 mg/kg, Hg 0.02 mg/kg and Cr6+ not detected.) in the soils of the palygrounds were lower than the worrisome level in criteria for area 1 in Korea soil environment conservation act. In addition, when the soil pollution grade (SPC) was evaluated as an average value, it was found to be less than 100, the first grade, at all points in the seven autonomous districts, indicating thatthe soil was in good soil condition. However, when evaluated as the maximum value, some of the five districts showed values of 100 or more. Therefore, it was found that continuous management and interest of the local government, which is the management body of children's playgrounds, is necessary for a safe soil environment.

서울 도심에 있는 어린이 모래 놀이터의 안전한 사용을 확인하기 위해 토양 중금속(Cd, Cu, As, Pb, Zn, Ni, Hg, Cr6+) 오염현황을 조사하였다. 시료 채취 장소는 서울시 7개 자치구에서 281개소를 선정하였다. 본 연구에서 중금속의 전체 평균 농도는 Cd 0.21 mg/kg, Cu 5.97 mg/kg, As 2.40 mg/kg, Pb 7.55 mg/kg, Zn 34.08 mg/kg, Ni 4.22 mg/kg, Hg 0.02 mg/kg였다. Cr6+은 불검출되어, 이를 포함하는 중금속 7종 모두 토양오염우려기준 1 지역 기준보다 낮은 것으로 나타났다. 아울러 토양오염등급(SPC)을 평균값으로 평가했을 경우에 7개 자치구 모든 지점에서 1등급인 100 미만인 것으로 나타나 건전한 토양 상태임을 보였다. 하지만 최대값으로 평가했을 경우 5개 자치구에서 일부 100 이상의 값을 나타내었다. 따라서 안전한 토양환경을 위하여 어린이 놀이터의 관리주체인 지자체의 지속적인 관리와 관심이 필요한 것으로 보인다.
