| 摘 要： | 结合黄河下游疏浚工程 ,通过现场取样和化验 ,确定了疏浚底泥的环境背景值。研究表明 :疏浚底泥的环境背景值与黄土高原土壤环境背景值有较好的关联性。跟踪观测结果显示疏浚固堤泥沙的重金属含量随时间变化不大 ,且小于土壤环境质量一级标准要求的限制值 ,不会产生二次污染。

| Abstract: | With the dredging projects in the Lower Yellow River, the environmental background values of the dredging silt have been determined by means of on site sampling and measurement. There are good relationships between the environmental background values of the dredging silt and soils of the loess plateau. The observed results demonstrate that heavy metal contents of the dredging silts for embankment reinforcement change with time slightly and may not result in the second pollution to the surrounding environment. |
