초록
본 연구는 공단지역 주민들의 환경오염물질에 의한 건강피해를 예방하기 위한 기초연구의 일환으로 수행되었다. 이를 위하여 공단지역 및 대조지역에 대한 토양 중의 환경오염물질과 다환방향족탄화수소화합물(PAHs)의 농도수준 및 분포특성을 조사하였다. 시료채취는 공단지역과 대조지역의 토양을 대상으로 실시하였으며, 토양 중의 중금속, VOCs(휘발성 유기화합물), PAHs 및 PCB(폴리클로리 네이티드비페닐) 등 토양오염물질 농도를 분석하였다. 직접노출군에 속하는 가까운 거리의 송도동, 해도동, 제철동 등은 거리가 먼 장기면에 비하여 비교적 높은 농도를 나타났다. 특히 배출원 주변의 직접노출지역(제철동) 이 대조지역(장기면) 보다 오염물질의 농도가 높은 것으로 조사되었다. 토양 중의 중금속 농도는 제1지역 우려기준에 비해 대체로 낮은 것으로 나타났으나, 아연은 전 지역이 제1지역 우려기준(300 mg/kg)의 약 20.8~58.9% 수준으로 비교적 높은 농도를 나타내었다. 불소는 모든 지점에서 기준치 이하로 나타났으나, 직접노출지역인 제철동의 경우 제1지역의 우려기준(400mg/kg)의 약 74% 수준으로 조사되어, 불소에 대한 모니터링과 배출원 관리가 필요한 것으로 판단된다. 또한, 유기인, PCB, 페놀류와 VOCs인 벤젠, 톨루엔, 에틸벤젠, 자일렌 등은 분석기기의 검출한계 이하로 나타났고, 석유계총탄화수소(TPH)의 경우에는 송도동이 높게 나타났다. 한편, 토양 중 PAHs 화합물의 농도 수준은 18.71~1744.59 ng/g이었으며, 발암가능물질 6종에 대한 PAHcarc의 농도수준은 6.54~695.94 ng/g을 나타내었다. 송도동에서 가장 높은 농도수준을 나타내어, 직접노출지역인 공업단지로부터 근거리 지점에서의 PAHs 농도가 원거리 지점인 간접노출지역보다 비교적 높은 농도를 나타내었다.
This study was performed to prevent the health damage of environmental contaminants in Industrial Complex Area. And, this study aimed to identify the concentration levels and distribution characteristics of environmental contaminants and Polycyclic Aromatic Hydrocarbons (PAHs) at soil in Industrial Complex Area and control area. The concentration of the soil pollution standard such as the heavy metals in the soil, VOCs, PAHs, and PCB were measured and analyzed using the soil specimens in the Industrial Complex Area and control area. Soil specimens from the Industrial Complex Area (the direct exposure area) and the control area were surveyed. Songdo-dong, Haedo-dong and Jechul-dong, which are in the direct exposure area and near the emission source, showed relatively high concentrations of contaminant materials when compared with Jangki-myeon, which is far off and in the control area. The concentration of zinc was 20.8-58.9% of the level of concern (300 mg/kg) in the 1st region, which is a relatively high concentration. The concentration of fluoride was under the standard in every region, but it was about 74% of the level of concern (400 mg/kg) in the 1st region. It is recommended that controlling fluoride emissions is necessary. Levels of organic phosphate, phenol, and VOCs like benzene, toluene, ethylbenzene and xylene were under the detection limit of the analysis instruments. The concentration of TPH was high in Songdo-dong. The concentration of contaminants in Jechul-dong was high. In addition, it was observed that the level of soil contamination changed depending on the distance from the emission source. The concentration of PAH compounds in the soil was 18.71-1744.59 ng/g, and the concentration of six potential cancer-causing PAH materials was 6.54-695.94 ng/g. The highest concentration was in Songdo-dong. The PAH concentration in the direct exposure area near the complex was relatively high compared to the indirect exposure area.
