Abstract The current understanding of Hg(II) photolytic reduction in atmospheric particles is inadequate. This study addresses the impacts of the particle chemical composition (e.g. anions, trace elements, and carbon concentrations) and water content on the Hg(II) photolytic reduction process under ambient conditions. The results showed that Hg(II) in particles was significantly reduced under irradiation and this process could be prohibited by certain heavy metals and promoted by increasing water content in particles. Negligible evolved Hg(0) amount was observed from particles under dark condition (occupying for

颗粒化学成分和含水量对颗粒结合汞光解还原的影响
摘要 目前对大气粒子中 Hg(II) 光解还原的认识是不够的。该研究解决了颗粒化学成分（例如阴离子、微量元素和碳浓度）和水含量对环境条件下 Hg(II) 光解还原过程的影响。结果表明，辐照后颗粒中的Hg(II)显着降低，该过程可以被某些重金属抑制，并通过增加颗粒中的水含量来促进。在黑暗条件下从粒子中观察到可忽略不计的 Hg(0) 释放量（占
