To determine the distribution of mercury (Hg) in the coastal surface sediments around the Korean peninsula, the baseline concentration of Hg was estimated, the extent of contamination was assessed, and the factors controlling the distribution were discussed. The concentrations of Hg in surface sedim...

사람 또는 환경에 미치는 수은의 악영향은 무엇인가? | 중금속 중 수은은 고대부터 많은 용도로 사용되어 왔으며 현재 약 3,000가지 이상의 용도로 사용되고 있다. 또한 환경 중에 배출되었을 때, 총 수은보다 독성이 강한 메틸수은(MeHg)으로 화학종이 변화될 수 있고, 인체에 축적될 경우 수은중독이나 미나마타 병 등을 야기 시키기도 한다. 이러한 수은의 악영향으로부터 전 지구적인 차원에서 사람의 건강과 환경을 보호하는 것을 목적으로 2017년 8월 17일에 미나마타 협약이 발효되었으며(유엔환경계획, United Nations Environment Program), 현재 국내 ‧ 외에서는 수은의 대기를 통한 장거리 이동특성과 장기간의 수은 농도변화를 추적하기 위해서 지역적, 국가 간, 대륙 간의 수은 모니터링 프로그램들이 운영 중에 있다(e. | |
수은은 화학적 형태에 따라 어떻게 분류 되는가? | 수은은 화학적 형태에 따라 크게 금속원소(Hg), 무기수은(HgCl2), 유기수은(CH3HgCl)으로 분류되며, 환경 중으로 배출 되는 수은은 대부분 무기 또는 원소 상 수은의 형태이다. 수계로 유입된 수은은 입자상 물질과의 큰 결합력(log(Kd)=4. | |
