本文研究应用通量箱 (FluxChamber)方法研究Hg在湖水表现挥发性汞的流通释放量 ,研究在贵州红枫湖进行 ,当水温在 2 0 - 2 4℃时 ,湖面汞的释放量在 89- 196ng·h- 1·m- 2 。平均 12 3ng·h- 1·m- 2 。汞的释放通量白天达到最大值 ,而夜间降到最小 ,湖泊表面挥发性汞的释放通量均具有显著的昼夜变化规律 ,湖面汞的流通量与太阳辐射相关 ,与底泥中汞含量也明显相关
In this paper, FluxChamber method was used to study the release of volatile Hg from Hg in lake waters. The study was conducted on Hongfeng Lake in Guizhou Province. When the water temperature was between 20 and 24 ℃, 196 ng · h-1 · m-2. Average 12 3 ng · h -1 · m -2. The flux of mercury released reached the maximum during the daytime, while the nighttime reduced to a minimum. The release fluxes of volatile mercury on the lake surface all had significant diurnal variation. The flux of mercury in the lake was related to solar radiation, and the mercury content in the sediment Obviously related
