Abstract

The objective of this study was to identify Pb pollution sources of sediments in Lake Andong. We analysed Pb isotopes in sediments from Lake Andong, soils and mining tails from the watershed as well as sludges and wastewater from zinc smelting facilities which exists in upper stream of Lake Andong. The Pb isotope ratios ($^{207}Pb/^{206}Pb$ and $^{208}Pb/^{206}Pb$) for sediments are $0.827{\pm}0.004$ and $2.041{\pm}0.015$, which showed similar values with those of mining tails, $0.815{\pm}0.002$ and $2.016{\pm}0.006$, respectively. The isotopic ratio values of soils existed in the range of 0.756~0.881 and 1.872~2.187. In imported zinc ores, the isotopic ratio values existed in the range of 0.816~0.956 (mean 0.832) and 2.029~2.219 (mean 2.059). These values were similar to those in zinc and lead concentrate originated from Canada and South America. Additionally, isotopic ratio values for sludge and wastewater were $17.515{\pm}0.155$, $15.537{\pm}0.018$, and $37.357{\pm}0.173$, respectively. The Pb isotopic ratio of sediments showed binary combination patterns with soil and mining tails, which were similar to those for Korean Pb ore.

본 연구는 안동호 퇴적물 중의 납 오염 기원을 조사하기 위해 안동호 퇴적물, 안동호 유역의 토양, 광미퇴적물 및 아연제련시설의 부산물 중의 납 동위원소를 분석하고 국내 외 결과와 비교하였다. 안동호 퇴적물 중의 $^{207}Pb/^{206}Pb$$^{208}Pb/^{206}Pb$$0.827{\pm}0.004$$2.041{\pm}0.015$로서 광미퇴적물의 $0.815{\pm}0.002$$2.016{\pm}0.006$와 유사한 값을 나타내었으며, 토양 중 $^{207}Pb/^{206}Pb$$^{208}Pb/^{206}Pb$는 0.756~0.881 및 1.872~2.187로 퇴적물 및 광미퇴적물에 비해 넓은 범위의 납 동위원소 분포를 나타냈다. 아연 광석의 $^{207}Pb/^{206}Pb$$^{208}Pb/^{206}Pb$는 0.816~0.956(평균 0.832), 2.029~2.219(평균 2.059)로서 비교적 넓은 범위의 동위원소 조성변화를 보였으며, 폐수 및 슬러지 중의 $^{207}Pb/^{206}Pb$$^{208}Pb/^{206}Pb$는 0.883~0.905(평균 0.887), 2.127~2.156(평균 2.133)로 나타났다. 안동호 퇴적물은 연화광산의 광상과 유사한 납 동위원소 분포특성을 보였으며, 광미퇴적물과 토양에 의한 혼합 특성을, 아연제련시설의 경우, 캐나다 및 호주 등으로부터 수입된 아연 광석에 의한 납 동위원소 분포와 유사한 분포 특성을 나타냈다.
