中文摘要 |
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。 |
英文摘要 |
After summing up the work of former researchers, the authors set up a instrument which can be used to measure the fluxes of volatile mercury over soil in field. From Aug. to Oct. in 1993, the authors studied the fluxes of volatile mercury over soil at five sites of three different areas (high mercury contented area, mercury polluted area and reference area). Studies showed that soil release more volatile mercury in day than at night, and that the fluxes of volatile mercury over soil has relationship with both the total mercury content of soil and air temperature. |
