  • 환경부의 정책중 하나로서 지정 폐기물제로서 산업 전 현장에서 생성되는 폐기물들을 매립 등 버리게 되었을 때 향후 토양오염 등 문제가 심각히 대두되는 품목들에 대해서 지정한 본 연구를 수행하기 위해 우선 환경부 허가부터 받기 위해 수개월을 보내면서 적지 않은 고민을 하게 된 것이 본 연구 수행에 오히려 도움이 되었다.(중략)

  • In this paper, we developed the algorithm which tracking the vehicle and deciding the moment of dumping in landfills. We first trace the position of vehicle using the difference image between current image and background image and then we decide the stop point from the shape of vehicle route and detect the dumping point by comparing the dumping image with the image that vehicle is stopping.

  • An illegal landfill In Korea was evaluated in a view of environmental quality to figure out reusing the area. The sampling spots were selected at a point in the landfill and three points in it's around area(two points in a paddy soils and one in a farm field). The eleven pollutants regulated in the Korean Soil Environmental Preservation Act (KSEPA) were analysed from the soil sample with the method of the KSEPA. As the results of the analysis the level of concentration with most samples indicated the requirement of the KSEPA. The concentration of soil samples met the standard: however, some pollutants in the ground water and leachate showed higher concentration than that of the requirement. Therefore, we must consider the treatments of the pollutants in the ground water and leachate when designing this landfill area for reusing.

  • This study was carried out to investigate the contamination characteristics of surface water, soil water and groundwater around and in antimony waste landfill site in Wonsung-ri, Yeonki-kun, Chungnam. The waste disposed in the study was excavated and transported to the other site in several years ago. For this study, we collected 35 water samples including groundwater, soil water and surface in the study site and also collected 2 groundwater samples from a comparison site. The data of chemical analysis of soil water samples show the antimony concentration of $48.75{\sim}74.81\;ppb$, which is much higher than groundwater in a comparison site and is highly excess than regulation level for a drinking water of some advanced countries. A relatively high antimony concentration was detected in three stream water samples nearby landfill site and two groundwater samples. Fe and Mn contents in soil water and stream water were measured as maxium 6.5 mg/L and 7.3 mg/L, respectively. Although other heavy metals of water samples in the study site are higher concentration than water sample of comparison site, their absolute levels are lower than regulation level for a drinking water. The chemical data of water samples are plotted widely from Ca - $HCO_3$ type to Ca - ($Cl +SO_4+NO_3$) type. Some groundwater show high contents of potassium and nitrate, which would come from fertilizer and sewage. Conclusively, some heavy metals including antimony have been still remained under the soil surface of the landfill site in the past. These metals have leaked out into nearby stream and groundwater system, and threaten the ecology, crops and the health of residents in this site. Therefore, the government have to prepare the strategy to prevent the diffusion of heavy metals into aquatic environment and have to process the reclamation work for contaminated site. It is also necessary to make a regulation level of the antimony concentration for a drinking water and soil environment in Korea.
