在总结前人工作的基础上，建立了一套野外现场测量土壤挥发性汞释放通量的实验装置，于１９９３－０８至１９９３－１０在贵州省三类地区（高汞区、人为乘污染区和背景参考区）的５个采样点进行土壤挥发性汞释放通量的研究。结果表明．土壤挥发性汞释放通量具有白天高于夜间的昼夜变化规律；土壤挥发性汞释放通量与土壤总汞含量、大气气温相关。 On the basis of summarizing the work of predecessors, an experimental set-up was set up to measure the flux of volatile mercury released from the field in the field. From 1993-08 to 1993-10, three experimental areas in Guizhou Province (high mercury area, man-made pollution area And background reference area) of five sampling points for soil volatile mercury release flux studies. The results show. Soil volatile mercury fluxes have daytime and nighttime variation patterns during daylight hours. Soil volatile mercury fluxes are related to soil total mercury content and atmospheric temperature.
