Exposure Assessment of Chemical Substances from Soil and Groundwater Environment

摘要

Exposure information due to hazardous chemicals in the environment is essential to assess risk to individual person, especially in soil and groundwater environmental media. In this paper scenarios of exposure from soil and groundwater environmental media and methodologies of exposure assessment are summarized to provide fundamentals for site and generic risk assessment of categorized chemicals. The methodologies of fate and exposure models are also discussed by conducting the case studies of exposure assessment for heavy metals, organic compounds, and dioxin compounds. In addition, the structure of exposure models and available data for model calculation are examined to make clear more realistic exposure scenarios and the application to the practical environmental issues.
