An overview of the US EPA's multiple pathway exposure methodology.
International Conference on Incineration and Thermal Treatment Technologies. Salt Lake City, UT, USA, 1998/05.
The US Environmental Protection Agency's National Center for Environmental Assessment is finalizing its updated approach to assessing the health risks from direct and indirect exposure to combustion emissions.
The prior 1990 Indirect Exposure Methodology has been used frequently in the early part of this decade, while the new methodology considers more pathways for agent transfer and exposure.
This advanced methodology is not limited to exposure from combustion emissions as the approach lends itself to assessing indirect exposure to other agents in various exposure scenarios.
The purpose of this presentation is to alert the user community to the new methodology and discuss its impacts on risk assessment.
A brief overview of the exposure pathways, along with the inherent uncertainties of the MPE and the risk characterization, are presented.
Other associated documentation is presented and referenced.
The paper concludes with a discussion of the planned implementation of the MPE and the Agency program guidance for use with RCRA combustor permitting and risk assessments.
