This study was carried out to evaluate the applicability of the soil washing process to remediation mercury-contaminated mine tailing or solid material (soil and sediments etc.) around abandoned mines. First, the physicochemical characteristics of mine tailing were analyzed through particle size ana...

국내 금속광산의 갯수는? | 국내에는 2,184개의 금속광산이 산재되어 있으며, 이 중에서 전체의 96.4%에 해당하는 2,106개 광산은 휴광 또는 폐광된 것으로 보고되었다(MIRECO, 2019). | |
국내 금속광산 중 휴·폐금속광산의 비율은 얼마인가? | 국내에는 2,184개의 금속광산이 산재되어 있으며, 이 중에서 전체의 96.4%에 해당하는 2,106개 광산은 휴광 또는 폐광된 것으로 보고되었다(MIRECO, 2019). 이러한 휴·폐금속광산 주변에는 과거 채광이나 선광·제련과정에서 발생된 폐(광)석, 광물찌꺼기 등의 광산폐기물들이 방치되어 광산 하부의 농경지와 수계의 환경오염을 유발하고 있다(Jung et al. | |
수은에 의한 대표적인 피해사례는? | 수은에 의한 대표적인 피해사례는 1956년 일본 미나마타시에서 메틸수은에 의해 발생한 미나마타병이며, 1976년 이라크에서 유기수은 농약에 오염된 곡류로 만든 빵을 섭취하고 약 500명이 중독되어 사망한 사례를 비롯하여 과테말라와 파키스탄에서도 유사한 사건이 발생한 바 있다(NIER, 2006). 국내의 폐광산의 대부분이 농경지와 인접한 곳에 위치하고 있으며, 그 주변으로 광물찌꺼기 및 폐(광)석이 잔재하는 것을 미루어 볼 때, 우리나라 토양과 농산물의 수은오염 가능성은 비교적 높을 것으로 판단된다. |
