ABSTRACT
Numerical examples of case studies and hypothetical problems are presented in the following sections to demonstrate some specific uses and typical applications of risk assessment in hazardous waste management. Chronic intakes are evaluated for the ABC site risk assessment, since it is expected that the potential receptors under the postulated exposure scenarios will experience long-term exposures. Consequently, in determining the health-based cleanup criteria for this site, the relationship for developing soil ALs for systemic toxicants is applied to the critical receptors. Information obtained on pertinent properties of proprietary organic surfactants used as substitute for mercury in the household batteries are extrapolated for completing the environmental impact and risk assessment. The concepts of risk assessment are employed in evaluating and comparing the feasible disposal options identified for the management of used household batteries. Realistic sets of exposure scenarios representative of the ABC site and vicinity are developed and evaluated to aid the risk characterization.
