Abstract

Phthalate esters are used as additives in plastics to improve mechanical properties, particularly flexibility. The contamination of soil samples by phthalate esters around four tributaries to the nm river was analyzed based on gas chromatography-mass spectrometry (GC-MS). All soil samples collected from the four tributaries, which include Anyangcheon and Seohocheon (expected polluted areas), and Gapyeongcheon and Namhan river (expected clean areas), were found to be contaminated by his(2-ethylhexyl) phthalate (DEHP). Soil around Anyangcheon was the most contaminated (113 ppb), about twofold higher than the ones around Seohpcheon (64 ppb), Gapyeongcheon and Namhan river (50 ppb). Based on the fact that DEHP contamination in sediments of the river tributaries around the country is as high as 2.04 ppm, it was concluded that DEHP contamination of the soils around the tributaries to the Han river is relatively low.

Phthalate ester는 플라스틱의 물리적 성질, 특히 유연성을 향상시키기 위하여 플라스틱 제품에 첨가하는 가소제이며 내분비계 장애를 일으키는 것으로 추정되는 물질이다. 본 연구에서는 우리나라 한강지류 하천 주변 토양의 phthalate esters의 오염 정도를 gas chromatography-mass spectrometry(GC-MS) 방법으로 분석하였다. 그 결과 예상 오염 지역인 안양천과 서호천, 그리고 예상 청정 지역인 가평천과 남한강 지역에서 채취한 토양시료 모두에서 bis(2-ethylhexyl) phthalate(DEHP)가 일정 수준 검출되었다. 그 오염 수준은 안양천 주변 토양이 113ppb로 가장 높았으며, 서호천 주변 토양이 64 pub,그리고 가평천과 남한강 주변 토양이 약 50 ppb이었다. 따라서 한강 지류 하천 토양의 DEHP오염은 국내 하천 저질의 DEHP오염 수준이 최고 2.04 ppm임을 감안할 때 상대적으로 낮은 수준임을 알 수 있었다.
