英文摘要	为了解黄河尾闾及近岸沉积物中重金属的污染特征,采用电感耦合等离子体质谱仪(ICP-MS)测定了黄河河道和河口48个样品中Cr、Cu、Zn、Cd、Pb和As等6种重金属的含量,并对其分布和生态风险进行了评价。结果表明,黄河尾闾及近岸重金属的总含量沿河道至河口方向呈现先增加后降低再增加的趋势,至近岸B断面,As、Pb、Cd和Zn含量呈明显增加趋势,Cu和Cr含量增加幅度较小;黄河河口沉积物中重金属浓度明显高于河道沉积物中重金属的浓度。与我国其他流域相比,研究区域重金属含量处于较低水平。潜在生态风险评价结果表明,黄河尾闾及近岸沉积物6种重金属潜在生态风险系数从高到低依次为:Cd>As>Pb>Zn>C...
中文摘要	To understand the pollution characteristics of heavy metals in surface sediments from the tail reaches of the Yellow River Estuary, the concentrations of Cr, Cu, Zn, Cd, Pb, and As in 48 sediment samples were analyzed using inductively coupled plasma source mass spectrometry, and the potential ecological risks of each heavy metals were evaluated. The total content of metals from the tail reaches of the Yellow River Estuary showed a trend of decrease then a subsequent increase after the first increase, until section B of coastal, the contents of As, Pb, Cd and Zn increased obviously, and the contents of Cu and Cr increased by a lesser extent. The heavy metal concentrations in the sediments of the Huanghe Estuary were significantly higher than those within the Huanghe Channel; however, compared with other typical areas along the coast of China, the heavy metal concentrations are relatively low. In relation to potential ecological risk factors, it was determined that the potential ecological risk of six heavy metals in sediments were in the order of: Cd>As>Pb>Zn>Cu>Cr; Cd and As contributed the most to the total potential ecological risk accounting for 55.90% and 29.54%, respectively. All sampling sites posed low potential ecological risks for the sea reach of the Huanghe River. These results provide base data for studies in ecological protection, environment management, and pollution control within the tail reaches of the Yellow River Estuary
