Emissions Characterization of Emerging Contaminants
Project number:





Air and Energy Management Division


Stationary Source Branch

Brief description of research project:

This research is focused on emissions characterizations from stationary and mobile sources with an emphasis on emerging contaminants and alternative fuels. In addition to emissions characterization from large-scale sources, this research will involve validating, modifying, and applying methods to assess experimental endpoints, with the potential to assist in new instrumentation/technologies for measurement of emissions from emerging contaminants (e.g. ethyene oxide [EtO] and condensible particulate matter). The ability of the individual to understand aerosols, combustion, and measurement technologies coupled with the ability to operate many instruments (including data reduction and analysis) will be a key part of the participants role in the research team. A source emissions specialist is needed to perform measurement and monitoring of emerging contaminants as well as those from emerging alternative fuel technologies. The individual would assist in development of new measurement technologies and instrumentation, conduct research on the quality of existing methods and metrics, and characterize emissions from many sources at lab-, pilot-, and full-scale. To a lesser extent, this person will also work with our partners to help broaden the understanding of these emerging contaminant emissions and their impacts on human health and environment. The participant will have the opportunity to publish and present findings to many research communities, at conferences and through internal presentations within EPA.
