| 中文摘要 |
| 应用Moss Bag监测元素汞的干湿沉降。结果表明:矿区大气汞浓度200-1135ng·m-3时汞的湿沉降为1700μg·m-2·a-1;干沉降987μg·m-2·a-1.而当距矿区67km,大气汞浓度3.4-4.0ng·m-3时,其干沉降21μg·m-2·a-1,湿沉降33μg·m-2·a-1,湿沉降占总沉降61%-63%,干沉降占37%-39%,元素汞的干湿沉降与距汞源的距离明显相关。 |
| 英文摘要 |
| Dry and wet deposition of element mercury was measured by moss bag in this study.The results showed that when concentration of atmospheric mercury is 200-1135ng·m-3,wet and dry deposition of mercury are 1700 μg·m-2·a-1,987μm·m-2·a-1 at the mercury mine area respactively.The concentration of gaseous mercury is 3.4-4.0ng·m-3,wet and dry deposition of mercury are 33 μg·m-2·a-1,21μg·m-2·a-1 respactively at the area which is 67 km from mercury source.Wet deposition is 61%-63% and dry deposition is 37%-39%. Dry and Wet deposition of element mercury are correlation with distance from mercury source. |
