摘　　要：通过对贵州省务川汞矿区土法炼汞的矿石、冶炼矿渣中汞含量的测定，运用质量平衡原理，计算土法炼汞过程中汞释放因子，估算土法炼汞过程中汞的年释放通量．贵州务川汞矿区土法炼汞的回收率为78．4％～93．6％，释汞因子为6．9％～32．1％，土法炼汞的年释汞量为3．7～9．6t．结果表明，务川汞矿区土法炼汞是该地区大气的最主要人为释汞源．By determining mercury concentrations in mercury ore and smelting slag samples, we used a mass balance method to calculate mercury emission factors and annual mercury emission from the indigenous method of mercury smelting in Wuchuan mercury mining areas, Guizhou Province. The mercury emission factors of the indigenous method ranged from 6.9% to 32.1% with the recovery from 78.4% to 93.6% and the annual mercury emission was up to 3.7 ～ 9.6 tons. The results highlighted that the indigenous mercury smelting was one of the most important anthropogenie atmospheric mercury emission sources in this region.
