痕量金属元素土壤环境质量基准研究进展

Research and Prospect on Soil Quality Benchmark for Trace Elements

土壤环境质量标准是土壤中各类污染物浓度水平的限值,而土壤环境质量基准和环境质量标准之间存在着必然的联系和一定的数值关系。对不同国家土壤环境质量标准的研究现状进行了简要论述,说明了土壤污染风险评价与建立基于风险的土壤环境质量基准之间的关系并阐述了痕量金属元素土壤环境质量基准建立的技术框架。在指出我国现有土壤环境质量标准存在的问题的基础上,探讨了有关我国土壤痕量金属元素基准及标准的修订和执行等方面的研究发展趋势。

Soil quality standard is the limited value of contaminant in the soil, and soil quality benchmark is correlated with soil quality standard necessarily and numerically. This paper discussed the development of research on soil quality standard in different countries. The relationship of soil risk assessment and risk-based soil benchmark establishment was expounded. On this basis, the problems of current soil quality standard in China were indicated. At the same time, the trends of soil quality benchmark and revision, enactment of soil quality standard in China were summarized.
