The objective of this research project is to focus on the central hypothesis of the Southern California Particle Center and Supersite, which is that organic constituents associated with particulate matter (PM)—including quinones, other organic compounds (polycyclic aromatic hydrocarbons (PAHs), nitro-PAHs, and aldehydes/ketones), and metals—are capable of generating reactive oxygen species and acting as electrophilic agents. They have a central role in allergic airway disease such as asthma and cardiovascular effects through their ability to generate oxidative stress, inflammation, and immunomodulating effects in the lungs and airways.
The specific objectives of this research project are to: (1) examine the association of the proximity of residences and schools to heavy traffic corridors with lung function, lung function growth, and asthma prevalence and incidence in children; and (2) enhance, refine, and evaluate mobile source emissions modeling techniques that are used to characterize the exposure of participants to mobile source emissions.
