soil sieve

This paper reviews the progress of ecological soil screening benchmarks with a particular emphasis on the methodologies and technical tips for the development of risk-based ecological soil screening benchmarks.

土壤生态筛选基准是指为了对陆地生物及关键的土壤生态功能提供适当保护而制定的土壤中污染物的浓度限值,污染物浓度超过此值,需对土壤采取进一步的风险评价行动或污染控制措施。
