US EPA 土壤和地下水区域筛选值

US EPA 土壤和地下水区域筛选值 (TR=1E-06, HQ=0.1) May 2016，我国计算基于致癌效应的土壤和地下水风险控制值时，采用的单一污染物可接受致癌风险为10E-6；计算基于非致癌效应的土壤和地下水风险控制值时，采用的单一污染物可接受危害商为1。美国这里计算基于非致癌效应的土壤和地下水风险控制值时，采用的单一污染物可接受危害商为0.1，严于我国。

he screening level (SL) tables are available for download in Excel and PDF formats. All tables are presented with target cancer risk (TR) of 1E-06, however, tables are presented with target hazard quotients (THQ) of 1.0 and 0.1. Use the tables appropriate for your region. These tables are considered ready for use. The tables contain both SL calculations and the toxicity values that were used. The download tables do not include the ingestion of fish exposure pathway, the outdoor worker and the indoor worker exposure to soil exposure pathway that are presented in theUser's Guide. These exposure pathways can be considered on a site-specific basis in the Calculator.
