About the Project

Airborne particulate matter (PM) can penetrate deep into our respiratory system, eliciting adverse health effects. World Health Organization lists PM as the largest environmental cause of premature death worldwide by 2050. PM also scatters sunlight, degrading visibility locally and regionally. Quantitative information on pollution sources is essential to the design of air quality policies. In this project, we consolidate and expand our expertise built over the past 15 years in PM measurements and modeling. The goal is to achieve robust real-time PM source identification and quantification that are suitable for routine 24-7 operation. Specifically, there are three objectives:

1.To develop and implement a robust platform for real-time and continuous monitoring of source-indicative molecular markers and elemental tracers in atmospheric particulate matter through integrating existing and new instrumentation.
2.
To develop and apply measurement-based real-time source identification and apportionment methods for determining and quantifying sources contributing to particulate matter air pollution.
3.
To improve understanding of air pollutant source apportionment and examine the influences of emission sources, meteorological conditions, and control strategies on air pollution and human health at both local and regional levels.
