探讨了不同水文季节(丰水期和枯水期)乌江河水中汞的赋存形态及其在流域内的时空分布,结果表明:乌江流域表层水体总汞的平均浓度分别为:丰水期65.9ng*l-1,枯水期16.6ng*l-1.乌江河水汞的主要形态为颗粒态,颗粒态汞占总汞的比例为丰水期84%,枯水期52%. |

The speciation and distribution of mercury were studied in the Wujiang river during the high flow and low flow periods. The concentrations of average total mercury were 65.9ng*l" in high flow period and 16.6ng-l"' in low flow period, respectively. The mercury in Wujiang river was mostly associated with suspended particles, and the particulate mercury constituted on an average of 84 % of the total mercury in high flow period, of 52 % of the total mercury inalow flow period, respec-tively. |
