摘要
本文研究了达米埃塔尼罗河支流底部沉积物中As、Co、Cu、Fe、Sb、Zn、Cd、Se、Ni、Pb的分布及其有效浓度。采用DTPA萃取法测定有效浓度。平均有效浓度排列为as > Fe > Cu > Zn > Co > Se > Ni > Pb > Sb > Cd。聚类分析表明，Damietta大坝建成前后两组重金属浓度存在明显差异。对结构分类和总有机质进行了研究。矩阵相关系数，与其他研究进行了比较评价。
Determination of available heavy metal concentrations in River Nile sediments, Damietta, Egypt
The present study investigates the distribution and available concentrations of As, Co, Cu, Fe, Sb, Zn, Cd, Se, Ni, Pb in the bottom sediment of the Damietta Nile branch. Available concentrations were determined using the DTPA extraction method. The mean available concentrations were arranged as follows As > Fe > Cu > Zn > Co > Se > Ni > Pb > Sb > Cd. Clustering analysis represents a clear difference between two groups of heavy metal concentrations before and after Damietta Dam. Textural classifications and Total organic matter have been studies. The matrix correlation coefficient, comparison between other studies has been evaluated.
