Investigating Traffic Exposures in Nepal

This work built a small cohort of traffic police officers and characterized their exposure to roadway pollutants, while looking at lung and cardiac function. The work is ongoing, and we will be back in Nepal in Fall 2016.

Fairbanks aerosol characterization

Fairbanks aerosol characterization

Fairbanks aerosol characterization

This project is investigating the nature of aerosol formation and chemistry in Fairbanks, Alaska in the winter time. Particulate matter levels regularly exceed federal standards, and this is especially apparent when it is most cold. Our work, along with colleagues from the University of Montana, the University of Fairbanks, and Washington University, provides the high time resolution data measurements of 24 metals, plus organic and elemental carbon. Field studies awere conducted in Dec 2011-Mar 2012.

Development of online measure of reactive oxygen

Particulate matter is regulated based on the mass per volume of air, yet it is clear that some particulate matter is more harmful to humans than others. This work, currently unfunded, couples a Particle-Into-Liquid Sampler with three measures of reactive oxygen species, which are a non-specific marker of stress in cells. By being able to quickly identify which components of PM are more harmful, we can improve our understanding of exposure and potentially reduce the effects associated with these exposures.

Investigating Near-Roadway pollution exposures in humans

In partnership with collaborators at NYU School of Medicine, we designed a novel high-volume sampler design (in a baby stroller) to collect filter samples of particulate matter (and several gas measurements) near an extremely busy roadway. Human volunteers, who are wearing Holter monitors to measure ECG parameters, walk along the stroller. We believe there is a direct link between exposures to specific components of PM that arise from roadway emissions that have an association with changes in cardiovascular paramaters.
