Abstract

Abstract: Through systematic investigation and comparative analysis of environmental standards for lead in soil from 15 typical countries and regions (covering Europe, North America, and Asia-Pacific), differences in standard limits, land use classification, and risk assessment methods were revealed.The results indicated that China’s environmental standard values for lead in agricultural soil were stricter than international counterparts; the risk screening values for lead in residential and industrial/commercial soil were consistent with the international median level, but the risk control values fell within the 75%~95% percentile range, indicating relatively lenient control. Significant differences in standard values for lead in soil among different countries and regions were attributed to four main factors: sensitive receptor selection, land use classification systems, exposure model parameter settings, and acceptable risk levels.

Key words: China, soil, lead, environmental standards, soil pollution, international positioning, implications, countries and regions
