Description:
The paper discusses particulate matter (PM) research at EPA's National Risk Management Research Laboratory (NRMRL) designed to provide critical information regarding emission rates, characteristics, and control approaches for PM 2.5 micrometers in aerodynamic diameter and smaller (PM2.5). NRMRL researchers are also studying penetration of outdoor particles into indoor environments, as well as indoor sources of particles. PM2.5 source profiles are being developed using a dilution sampling system to capture both primary particles and particles formed by condensation of organic compounds. This research will provide information needed by source receptor models to identify the contribution of different sources to the ambient particle loading. Emissions characterization research is being conducted on particle size and composition for residential wood combustion systems, for industrial combustion sources burning coal and heavy fuel oil, for diesel truck engines during on-road operation, and for open burning of biomass. Emission inventory research on ammonia from animal feeding operations and fugitive dust from construction activities will improve understanding of PM2.5 sources and their impact on atmospheric chemistry and ambient PM2.5 concentrations. NRMRL researchers are studying innovative technologies for stationary sources.
