中文摘要:通过查阅国内外共97 篇文献, 获得了14 种重金属在国内外河道底泥中的污染情况, 通过统计分析, 得到了国内外重金属污染的整体情况。运用潜在生态风险指数法、地积累指数法、富集因子法这3 种常见的重金属评价方法, 对国内外重金属的污染情况进行了评价。结果发现, 国内外对重金属的研究在种类、频次上都存在较大差别, 国内外河道底泥中的重金属含量差别也较大。3 种评价方法的侧重点和原理不同, 对国内外重金属的污染情况评价结 果也不尽相同。

Evaluation of the Heavy Metal Contamination in River Sediment Basing on Three Methods
Abstract:The contamination of river sediments about 14 heavy metals had been obtained referring to 97 articles from home and abroad. By statistical analysis, the overall situation had been achieved. Potential ecological risk index, geo-accumulation index and enrichment factor were chosen to evaluate the contamination of heavy metals from home and abroad. The three methods were all commonly used in assessment of heavy metals pollution. The results indicated the species and frequency of heavy metals were significantly different between domestic and abroad research. The contents of heavy metals of river sediments were various at home and abroad. Because of different principles and emphases focused on, the assessment results of the three evaluating methods were inconsistent.
