Title: Characterization of Air Toxics and Greenhouse Gas Emission Sources and Their Impacts on Community-Scale Air Quality Levels in Disadvantaged Communities

Principal Investigator / Author(s): Mellqvist, Johan

Contractor: FluxSense, Inc.

Contract Number: 17RD021

Research Program Area: Emissions Monitoring & Control

Topic Areas: Greenhouse Gas Emissions, Toxic Air Contaminants

Research Summary:

Industrial and agricultural emissions of GHGs (methane and nitrous oxide) affect present and future climate and volatile organic compounds (VOCs) significantly contribute to the formation of ground level ozone which constitutes a public health concern. Facilities emitting significant amounts of GHGs and VOCs may also emit BTEX and other air toxics that have a direct health impact on surrounding communities. This proposed research project aims to develop a better understanding of the actual emissions of various species from certain industrial facilities and methane super emitters. The project will also study the impact of these emissions on air quality/air toxic levels in disadvantaged communities close to the sources.

The results will provide a deeper understanding of the sources impacting the overall air quality in the State. The study aims to provide improved emission factors for methane, nitrous oxide, non-methane VOCs, BTEX, and where applicable SO2, NO2, formaldehyde, and ammonia for various source sectors and methane super emitters. Furthermore, the impact of the emissions from these sources on air quality/air toxic levels on nearby disadvantage communities will be researched through real-time mobile concentration measurements. The proposed research project will map concentrations on the ground of VOCs and other air toxics, identify the probable sources of these concentrations, provide insights to emissions exposure, and improve the understanding of potential health impacts.
