In Los Angeles's Pacoima neighborhood, residents are deploying Aeroqual sensors to document air pollution that official monitors miss. The densely packed community sits wedged between Interstate 5, Interstate 405, and heavy industrial facilities, creating a hyperlocal pollution hotspot that often escapes detection by the California Air Resources Board's sparse monitoring network.
Pacoima Beautiful, a local environmental organization, installed shoebox-sized Aeroqual sensors on residential properties to measure fine particulate matter, nitrogen dioxide, and ozone at street level. The sensors transmit real-time data, allowing residents and advocates to build a granular map of air quality across the neighborhood.
Jose Luis Salas and Shance Taylor, an environmental project manager, installed monitoring equipment on Salas's house as part of this grassroots effort. The community-led approach addresses a critical gap in California's air monitoring infrastructure. Official regulatory monitors sit miles away in areas like Long Beach, leaving neighborhoods like Pacoima with incomplete exposure data.
The stakes are direct. Pacoima residents experience elevated asthma rates and respiratory illness tied to chronic vehicle emissions and industrial pollution. Children in the area face compounded health risks from daily exposure to traffic-adjacent air quality far worse than countywide averages.
Pacoima Beautiful's sensor network transforms invisible air pollution into visible, measurable data. The organization plans to use this hyperlocal monitoring to support advocacy for stronger zoning restrictions, traffic rerouting, and enforcement of existing air quality standards. The data also provides documentation for residents pursuing environmental justice claims against polluting facilities.
This model reflects a broader shift in environmental monitoring. Communities facing disproportionate pollution burdens increasingly deploy affordable sensor networks rather than wait for government agencies to adequately regulate their airsheds. The approach enables residents to name and quantify harms officials often overlook, converting neighborhood-
