Outdoor Air Pollution

Outdoor air pollutants are emitted from a variety of sources including traffic and other transportation, agriculture, wildfires, and industry. Consequently, the general population is exposed to a heterogenous mixture of particles and gases with varying chemical constituency. DCEG researchers investigate various outdoor air pollutants thought to be associated with cancer risk. These include the traffic-related pollutants most concentrated in urban settings, as well as those arising from agricultural and other industrial activities.

Ambient Emissions from Industrial Sources
Ongoing efforts to examine emissions from industrial sources, verify proximity-based emission exposure metrics, and evaluate their associations with non-Hodgkin lymphoma and other cancers

Ambient Outdoor Ultrafine Particulate Matter and Lung Cancer Risk
Investigation of the etiologic relationship between long-term exposure to ambient outdoor ultrafine particle pollution and lung cancer risk in southern California

Outdoor Air Pollution from Intensive Animal Agriculture
Studies of ambient pollution exposures from concentrated animal feeding operations and their associations with health outcomes in the Agricultural Health Study cohort
