Enhancing Personal Air Pollution Exposure Data for Mechanistic Health Research

The award funds the development of a novel, low-cost method to estimate particle size in personal air pollution exposure monitoring, aiming to improve health research and public health interventions related to ultrafine particulate matter exposure.

Description

This project addresses a critical gap in personal exposure monitoring of airborne particulate matter, particularly ultrafine particles (~1000 times smaller than width of human hair), which are linked to respiratory, cardiovascular, and neurological health effects. By developing a novel low-cost, field-deployable particle size estimation method using existing technology, the project supports improved exposure assessment in high-risk environments, including those impacted by strong emission sources, whether outdoors or within a household. In the long term, the technology can inform regulatory policy, environmental health interventions, and global efforts to reduce the disease burden associated with air pollution.
