阿哈水库沉积物总汞及甲基汞分布特征OA北大核心CSCDCSTPCD
Distribution patterns of total mercury and methyl mercury in Aha Reservoir sediment
为弄清阿哈水库沉积物是否受到历史矿山废水输入对沉积物总汞及甲基汞垂直分布的影响,对沉积物总汞及甲基汞的含量和其垂直分布特征进行了研究.结果表明,阿哈水库沉积物总汞含量变化范围为160～252 ng·g-1,平均为210 ng·g-1,明显高于其他未受到污染的水库沉积物.沉积物中总汞含量随沉积物深度增加呈增加趋势,与其沉积环境有关.沉积物中甲基汞含量变化范围为0.2～7.2 ng·g-1,平均为1.8 ng·g-1,丰水期甲基汞含量随深度增加逐渐下…查看全部>>
In order to make clear whether the sediment in Aha Reservoir was contaminated by the mercury ( Hg) from mining wastewater drainage, an investigation was conducted on the vertical distribution patterns of total Hg (THg) and methyl Hg ( MeHg) in the sediment. The THg concentration in the sediment ranged from 160 to 252 ng · g-1, with an average of 210 ng · g-1 , being obviously higher than that in uncontaminated lakes. The THg concentration increased with sed…查看全部>>
