| 摘 要： | 应用通量箱方法研究Hg在贵州红枫湖水表面挥发性汞的释放通量。当水温在20－24℃时，湖面汞的释放量在89－196mg/(h.m^2)之间，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。

| Abstract: | A flux chamber technology can be used to measure the mercury flux between the atmosphere and the lake surface in area of mercury emission. Measurements have been performed over the Hong Feng lake. the measured fluxes (water temperature 20 - 24℃ ) were within the range 89 - 196 (ng/ ( h· m2 ) ) (average 123 (ng/ ( h· m2 ) ) . Measured fluxes were higher in daytime than in nighttime. Mercury fluxes are correctional with light emission as well as Mercury contents in sediments. |
