Associate Professor Edmund Seto of the Department of Environmental and Occupational Health Sciences is working with a low-income, primarily Latino community in Imperial County, CA, to measure air pollution using mobile devices he developed. The community has consistently had one of the highest asthma hospitalization anMod emergency room visit rates in the state for school-aged children.

However, a limited number of air pollution monitors makes it difficult to identify and address locations of concern. The project is in collaboration with community residents, Comité Cívico del Valle – a group that advocates for health and the environment – and the California Environmental Health Tracking Program. Information will help develop policies and practices to reduce exposures.
