Environmental Health Impact Assessment

Environmental health impact assessment is described as an integral part of environmental impact studies. As such, it must be included in the planning of engineering projects. A methodological approach is presented which involves four steps: (1) Identification of the initial perturbations in the environment; (2) tracing perturbations through the environment to determine the magnitude and duration of the exposure to the receptor population; (3) identification of the receptor population and its high risk subgroups; and (4) estimation of these impacts by applying derived exposure-response functions.
