| 摘 要： | 在黄河口湿地的枯水期(2009年4月)和丰水期(2009年6月)分别采集表层沉积物样品,分析了Cu、Pb、Zn、Cr、Cd、As、Hg的含量与分布特征.结果表明,Cu、Pb、Zn、Cr、Cd、As、Hg的平均含量分别为(22.1±5.2), (53.8±7.6), (78.4±13.2), (60.5±8.9), (0.250±0.099), (7.7±2.7), (0.055±0.039)μg/g.黄河口湿地表层沉积物中重金属含量处于国内河口湿地中等水平,低于欧美发达国家河口湿地的含量.有机质的含量影响了枯水期黄河口湿地表层沉积物中重金属的含量.Cu、Zn在枯水期以及As、Hg在丰水期与细粒径颗粒物显著正相关,<16μm的细颗粒物能吸持较多的重金属.

| Abstract: | Concentrations of heavy metal(Cu,Pb,Zn,Cr,Cd,As,Hg) were determined in the surface sediment of the Yellow River Estuary wetland during the dry(2009 April) and flood seasons(2009 June).The average concentrations of Cu,Pb,Zn,Cr,Cd,As,Hg were:(22.1±5.2),(53.8±7.6),(78.4±13.2),(60.5±8.9),(0.250±0.099),(7.7±2.7),(0.055±0.039)μg/g,respectively.The concentrations of the heavy metals were in the medium level in domestic wetlands,lower than those of the developed countries wetland in Europe and America.The distribution of heavy metals was mainly controlled by the variation of organic matter in dry season.Concentrations of Cu、Zn in dry season and As、Hg in flood season correlated well with the fine particles. |
