摘要
本文综述了铅锌冶炼废气中重金属污染物对土壤的累积影响,构建了重金属自然沉降后在土壤中累积富集的模型,介绍了两种常用的土壤重金属累积影响预测方法,通过应用实例对两种预测方法进行了对比分析,得出的结论相近,进而定量预测了铅锌冶炼废气中重金属对土壤的累积影响,为环境影响评价和环境管理提供了理论依据。
The cumulative effects of heavy metal pollutants in the waste gas from lead and zinc smelting on soil are reviewed; heavy metal enrichment model after natural sedimentation accumulation in the soil is constructed; two kinds of cumulative impact prediction methods commonly used for heavy metals in the soil are introduced. The two prediction methods are compared and analyzed by practical examples, and the conclusions drawn are similar. Furthermore, the cumulative impact of heavy metal pollutants in the waste gas from lead and zinc smelting on soil is predicted quantitatively, and it provides a theoretical ba- sis for environmental impact assessment and environmental management.
