简介：在湄公河河盆的水文学政体，沉积和水质量的资源发展和变化吸引了大注意。这研究试图在这条国际河里在重金属的transboundary污染上提高学习。在这研究，八个采样地点被选择沿着湄公河河的主流收集床沙样品。另外，5个重金属元素的内容和他们沿着河的主流的空间可变性被分析。geoaccumulation索引(Igeo)和潜在的生态的风险分析被采用在湄公河河的主流估计重金属污染地位。结果证明重金属元素Zn的平均内容是91.43mg/kg，Pb是41.85mg/kg，并且这是在上面的湄公河的床沙的21.84mg/kg河，比那些高，Zn68.17mg/kg，Pb28.22mg/kg，作为14.97mg/kg)在更低的湄公河。在更低的湄公河的Cr的平均内容是418.86mg/kg，比那高在上面的湄公河(42.19mg/kg)。LuangPrabang与422.90mg/kg与762.93mg/kg和Pakse有很高的Cr集中。8个采样地点的在所有的Cu的集中是类似的，除了在有11.70mg/kg的Jiajiu和有7.00mg/kg的Jiebei。当时，geoaccumulation索引的结果表明污染由Zn和Pb引起了Pb并且这多于由在上面的湄公河的Zn的那些。Cr是在更低的湄公河的主要污染物质，特别在LuangPrabang和Pakse。细微污染与作为也发生在Pakse。潜在的生态的风险索引显示在湄公河河的主流的重金属的潜在的生态的风险是低的。我们主张水质量的污染和在床沉积的重金属的污染在湄公河由矿物质资源或geochemical背景价值的采矿引起了没被播送从对更低的湄公河上面因为沿着河的水库沉积和冲淡。
