重点是收集土壤气体样本，以评估地下蒸汽对室内空气暴露途径的重要性。虽然土壤气体收集不是评估这一途径的唯一手段，但在美国石油学会（API 1998）和美国环境保护局（USEPA 2002a）最近发布的指南中，土壤气体起着重要作用。例如，这些数据可用于帮助做出以下决策:-资源保护和恢复法案（RCRA）纠正措施人类健康暴露的环境指标（EI）现有建筑中的当前暴露场景- 现有建筑物的未来暴露场景未来建筑物的未来暴露场景

Focuses on the collection of soil gas samples for assessing the significance of the subsurface-vapor-to-indoor-air exposure pathway. While soil gas collection is not the only means of assessing this pathway, soil-gasplays a prominent role in recent guidance published by the American Petroleum Institute (API 1998) and the Unites Stated Environmental Protection Agency (USEPA 2002a). Fir example, these data can be used to help make decisions concerning:-Resource Conservation and Recovery Act (RCRA) corrective action enviromental indicatiors (EI) for human health exposures-Current exposure scenarios in existing buildings-Future exposure scenarios in existing buildings-Future exposure scenarios in future buildings
