利用聚四氟乙烯动态通量室研究了城市污水污泥改性土壤中汞的去向和大气排放。阳光介导的氧化汞原位还原为挥发性单质汞（Hg-0）导致汞从土地污泥向大气输送。氧化汞还原为Hg- o发生在表层土壤的浅层(
We studied the fate and atmospheric emission of mercury (Hg) from soil amended with municipal sewage sludge using a Teflon dynamic flux chamber. A sunlight-mediated, in situ reduction of oxidized Hg to volatile elemental mercury (Hg-0) resulted in the atmospheric transport of Hg from land-applied sludge. The reduction of oxidized Hg to Hg-O occurred in a shallow layer of surface soil (
