Study of mercury bioaccumulation and intake pathway of oyster (Crassostrea sp.) from post-desulfurization waste seawater discharged from a coal fired power plant
汞(Hg)是对人类最具毒害的元素之一。在环境Hg污染中，以人为源为主。近年来，为削减SO2对大气的污染，许多沿海地区的燃煤火力发电厂采用烟气海水脱硫(SFGD)工艺，但在SO2被海水吸收排海的同时，燃煤中大量的Hg也被吸收、排放到海域中。这部分Hg可被海洋生物直接利用、累积，并沿食物链逐级传递、放大，最终危害人类健康。因此，作为海洋环境中新的Hg污染源，SFGD燃煤电厂脱硫海水中的Hg及其对海洋生物的影响值得关注。 本论文以厦门SY电厂附近海域为研究区域，配备SFGD装置的燃煤电厂排放的脱硫海水为研究介质，巨牡蛎为指示生物，系统性地研究脱硫海水中Hg在巨牡蛎体内的累积及其毒性效应、脱硫海水的...Mercury (Hg) is one of the most toxic elements to human body. Anthropogenic activities are main sources for Hg pollution in the environment. In recent years, seawater flue gas desulfurization (SFGD) technique has been applied by many coal fired power plants in coastal areas to reduce SO2 pollution in atmosphere. However, while SO2 is neutralized with the seawater and discharged from the power plan...学位：理学博士院系专业：海洋与环境学院环境科学与工程系_环境科学学号：2262008015013
