选取乌江流域上两个典型的水库（乌江渡水库和东风水库）作为研究对象，对不同季节水库水体中溶解性气态汞进行研究。结果显示：两个水库溶解性气态汞均明显表现为上层水体□下层水体，夏季□春季、冬季。水库中溶解性气态汞的含量受太阳辐射和水体中溶解性有机碳两个因素共同控制。 |

Concentration of dissolved gaseous mercury (DGM) in water profile were determined during various seasons in Wujiangdu Reservoir and Dongfeng Reservoir, two typical hydroelectric reservoirs both located on the up-mid stream of Wujiang River. Results showed that the concentration of DGM in the upper water column was obviously higher than that in the deep layer, with concentrations in summer significantly higher than that of the winter and spring. The distribution, speciation and levels of mercury within the reservoir water body were governed by two factors to some extent including water temperature and dissolved organic carbon. |
