The National Science Foundation (NSF) awarded a $452,993 Project Grant to The Washington University in St. Louis to conduct research on the role of indoor dust in modulating indoor air chemistry. The grant, provided under NSF's Geosciences program (CFDA 47.050), will enable the university to:
- Characterize the chemical transformation pathways and resulting products from target dust-bound precursors exposed to outdoor pollutants that infiltrate homes.
- Identify novel chemical reaction products in lab-generated and genuine complex mixtures of fresh and aged indoor dust using non-targeted mass spectrometry.
- Determine the oxidative potential and exposure risks of fresh and aged dust-bound and re-volatilized product mixtures.
The project aims to advance the understanding of indoor dust chemistry and its impact on human health, with the results disseminated through an interactive web tool. The award also supports summer research opportunities for students from Lincoln University, a historically Black institution.
