| Abstract | Municipal sewage has been identified to be an important source of mercury (Hg) to the environment. However, as the major sink of sewage-borne Hg, sewage sludge (SS) remains unresolved in terms of the occurrence status of Hg species. We presented here, a nation-wide survey on the speciation of Hg in SS of China. Total Hg (THg) and methylmercury (MeHg) were detected in all SS samples, within ranges of 0.4-12.4 mg/kg and 0.1-27.0 mu g/kg, respectively. Sludge-borne Hg mainly occurred in the mercury sulfide and organo-chelated phases, with only tiny portions occurring as soluble Hg. The mass loadings of sludge-borne THg and MeHg in China for year 2016 were estimated to be 12.2 metric tons and 19.9 kg, respectively. Landfill was the most important sink of sludgeborne Hg, followed by incineration, land application, and building materials. |
