Particulate Exposures in Asthmatic Kids (PEAK)

This project is part of the Obese Asthma Center (PI: Nadia Hansel), funded by the NIEHS and EPA. The broad aim of this work is to determine which potentially modifiable factors of fine particulate matter, including ultrafine particulates (UFP; particles with diameter <100 nm), microenvironment (home vs. school vs. transit), and peak exposure, are associated with respiratory effects in inner-city children with asthma.

A second, related objective is to evaluate the effects of these fine PM factors on overweight children with asthma, a susceptible population recently identified by our research team. To do so, we will examine the effects of PNC, microenvironment, and peak PM exposure in a panel study of 50 children aged 12-17 with asthma (half lean, half overweight) living in Baltimore City.
