초록
이 연구에서는 국내 휴・폐금속광산 주변의 논토양 120개의 시료를 채취하여 비소 및 중금속 함량을 왕수분해법을 통해 확인하고 1M MgCl2과 0.01M CaCl2을 활용하여 금속의 이동도를 평가하고자 하였다. 화학적 용출법을 이용하여 분석한 결과, 용출제로 용출한 비소와 중금속 농도에 대한 왕수 추출 농도의 비로 정의되는 상대적인 추출비(RER)는 1M MgCl2 > 0.01M CaCl2 순으로 나타났다. 원소별로 비교하면 Cd은 다른 원소에 비해 상대적으로 높은 추출율을 보이며, 이는 지구화학적 이동도가 높은 원소이기 때문으로 판단된다. 화학분해 방법에 따른 함량 변화는 통계적으로 유의한 양의 상관관계를 보이며(p<0.001), 1M MgCl2이 0.01M CaCl2보다 통계적으로 유의한 결과를 얻었다. 이 연구에서는 토양의 용출율에 영향을 주는 토양의 원소 함량과 물리화학적 특성을 이용하여 다중선형회귀분석을 수행하였으며, 그 결과는 비소 및 중금속의 농도 예측에 유용하게 사용할 수 있을 것으로 판단된다.
Abstract
This study evaluated extraction rates of As and heavy metals in soils using representative three soil extraction procedures. The three chemical leaching methods by aqua regia, 1M MgCl2 and 0.01M CaCl2 wereexamined to evaluate metal mobility for 120 paddy soils from abandoned metal mines. As results of chemical analysis, relative extraction ratio(RER) defined as elements extracted by extractant divided by those by aqua regia for As and heavy metals in the samples increased in the order of 0.01M CaCl2 < 1M MgCl2. The RER values for Cd were relatively higher than those for As, Cu and Pb due to their differences in geochemical mobilities. According to statistical analysis, significant correlation was found between those three methods(p<0.001). This study also established a stepwise multiple linear regression analysis for identification of dominant factors influencing metal extraction rates of contaminated paddy soils from mining sites.
