  • 摘要: 对贵阳市和武汉市的5座城市生活垃圾填埋场大气中的ρ(气态总汞)进行了测定,并分析了填埋场的大气活性气态汞、颗粒态汞、单甲基汞和二甲基汞的质量浓度分布. 结果表明:5座填埋场ρ(气态总汞)为1.6~473.7 ng/m3,不同采样点的平均值为8.5~155.7 ng/m3,最高值出现在填埋场的工作面及工作面下风向区域;而封闭填埋场或运行填埋场的覆土区的ρ(气态总汞)较低. 天气条件和垃圾处理活动均可影响ρ(气态总汞)水平. 贵阳高雁垃圾填埋场大气ρ(活性气态汞),ρ(颗粒态汞),ρ(单甲基汞)和ρ(二甲基汞)的平均值分别为37.4,255.3,12.4和12.7 pg/m3. 虽然不同形态汞的质量浓度明显高于全球背景值,但其产生的环境风险不大.
