초록

A study was carried out on the physico-chemical properties of soil and content of heavy metals and benzo(a)pyrene that might have been introduced through by-product fertilizers or air pollution to growing turfgrass at natural turfgrass playgrounds in elementary schools located at the western coast and eastern mountain areas in Jeollabuk-do, Korea. The soil of turfgrass playgrounds is composed of loamy sand, and the CEC and organic matters were very low. Compared to agricultural land in Korea, the concentrations of nitrogen, phosphorus and potassium were very low, requiring control in terms of nutrients. The contents of total and fraction heavy metals in soil were found to be background level. The reason may lie in the fact that unpolluted sand soil or sand was used to construct the foundation for the natural grass playground in the first place. However, any change in oxidation-reduction conditions or acceleration of decomposition of organic compounds may release some heavy metals from the soil and be transformed into forms that may be easily absorbed by plants or grass. It is believed that sustained monitoring and environment impact assessments should be carried out. The contents of enzo(a)pyrene in soil showed an average 0.60ng/g with a range between 0.06 to 1.47ng/g. The detected contents were found as background level.
