Zhejiang Daxue xuebao. Lixue ban, 2008 燃煤烟气中汞排放引起的污染越来越受到人们的关注，主要的原因则是其中的元素态汞(Hg0)由于其低熔点、高平衡蒸汽压以及低水溶性而难以在传统的烟气净化装置中去除.本试验采用固定床活性炭(AC)吸附元素态汞，结果表明，活性炭对汞的吸附取决于活性炭的量、活性炭颗粒大小、汞初始浓度、反应温度以及氯化物浸泡等因素的影响.

Study on temporal and spatial variation of mercury in sediments of Jiulongjiang Estuary [PDF]
, 2015 汞是一种可全球循环的持久性有毒污染物。在全球对汞污染状况越来越重视的大背景下，作为福建省第二大河流以及厦漳地区主要水源地的九龙江的汞污染理应受到更多关注。厦门SY电厂是九龙江河口区域内汞污染的重要点源，对其周边海域沉积环境进行长期监测并作综合评价，是十分必要的。常规的汞浓度及形态分析法在汞污染的溯源及追踪方面显得无能为力，而近年来兴起的稳定同位素分析技术，为深入研究汞污染源及迁移转化提供了新方法。 本文以九龙江河口为研究区域，探讨沉积物中汞的污染特征，解析汞的来源，主要内容和结果如下： （1 ...

Wildlife Letters, Volume 3, Issue 4, Page 143-151, December 2025.Effects of methylmercury bioaccumulation on survival of Columbia Spotted Frogs were modified by sex and length and were mediated by corticosterone (a glucocorticoid hormone) whereas effects of chytrid fungus were limited. ABSTRACT Amphibians have suffered widespread declines caused by many interacting factors whose effects are often difficult to ...

Mercury isotope fractionation during the processes of a seawater desulfurization coal-fired power plant and isotopic tracing of mercury pollution in surrounding atmospheric [PDF]
, 2016 汞是一种全球性的有毒重金属元素，由于形态多变，其生物地球化学循环过程十分复杂。大气中的汞主要来自于人类活动，燃煤是最主要的汞排放源。目前，海水脱硫工艺广泛应用于我国沿海地区的燃煤电厂中。与其他脱硫工艺不同，配备海水脱硫系统燃煤电厂的汞排放除了通过烟气排入大气外，还包括不可忽略的脱硫海水中的汞向大气的迁移扩散。因此，研究配备海水脱硫系统的燃煤电厂的汞排放特征对周边大气的影响，具有十分重要的意义。 本研究以厦门市一座配备有典型海水脱硫系统的燃煤电厂（SY电厂）的周边大气环境作为研究区域 ...
