Abstract

Organic pollutants that contained in stream sediments have origins of mountain soil in natural and cattle manure in human activity. Nitrogen and carbon isotope analysis for mountain soil, cattle manure and stream sediment were performed for contribution evaluation of organic pollutants in Toil stream of Yeongju dam basin. Average carbon isotope ratio(δ13C) is -25.17‰, -22.34‰, and -26.39‰ for river sediments, cattle manure and mountain soil, respectively. Result of carbon isotope analysis suggests that river sediments are more affected by acid soils. Average value of the nitrogen isotope ratio (δ15N) is 9.46% for river sediment, 1.99% for mountain soil, and 19.53% for cattle manure. Result of nitrogen isotopic analysis show that contribution of cattle mature is slightly higher than that of mountain soil in Toil stream sediments.

Keywords stream sediments, organic pollutants, mountain soil, cattle manure, carbon and nitrogen isotopes

요 약

하천퇴적물에 포함된 유기 오염물질의 기원은 다양하지만 주로 자연 기원의 산토양과 인위적 기원인 우분으로 구분할 수 있다. 영주댐 유역 토일천의 하천퇴적물에 포함된 유기오염물질의 기여도를 평가하기 위하여 산토양과 우분 및 하천퇴적물의 질소와 탄소 동위원소 분석을 수행하였다. 탄소동위원소비(δ13C) 평균값은 하천퇴적물 –25.17‰, 우분 –22.34‰, 산토양 –26.39‰으로 하천퇴적물은 산토양의 영향을 조금 더 받은 것으로 판단된다. 질소동위원소비(δ15N) 평균값은(‰)는 하천퇴적물 9.46‰, 산토양 1.99‰, 우분 19.53‰이다. 질소동위원소 분석결과에 의하면 토일천 하천 퇴적물은 자연기원의 산토양보다 인위적 기원인 우분의 기여도가 약간 더 높은 것으로 추정된다.
