Exposure investigations (EIs) are used
in emergency or time-critical situations like train derailments in
which dangerous or toxic chemicals have been released or where
people living in areas with contaminated soil are concerned that
they have been unusually exposed. EIs are intended to be a public
health service-- not research. Many communities, state and local
health departments, and the Environmental Protection Agency (EPA)
have come to rely on EIs conducted by ATSDR. EIs are an approach
developed by ATSDR that employ targeted biologic (e.g., urine,
blood, hair samples) and environmental (e.g., air, water, soil, or
food) sampling to determine whether people are or have been exposed
to unusual levels of pollutants at specific locations (e.g., where
people live, spend leisure time, or anywhere they might come into
contact with contaminants under investigation). This time-critical
service is authorized by the Comprehensive Environmental Response,
Compensation, and Liability Act (CERCLA).
