Description:
This report documents the development and demonstration of a new breath sampling method for volatile organic compounds (VOCs). The project, part of EPA's Total Exposure Assessment Methodology (TEAM) Program, was aimed at improving the existing field method for sampling exhaled breath. The new method was tested on four subjects exposed to elevated chemical levels in six microenvironments (hardware stores, swimming pools, garages, etc.). Repeated breath measurements before and after exposure provided data on the uptake and excretion of 20 VOCs.
