Particulate Matter

Industrial facilities such as metallurgical, mineral, and wood product manufacturers release dust particles (PM10) that affect air quality and public health. Monitoring these emissions helps reduce exposure and protect nearby communities.

Construction activities generate dust—also known as PM10 air pollution—that can harm workers and nearby residents, contributing to respiratory issues and long-term health risks. Monitoring and mitigation strategies are necessary to reduce PM10 exposure and improve air quality near active construction projects.

Proximity to freeways increases exposure to harmful air pollutants linked to serious health risks. Vehicular air pollution can spread over a mile from its source, with disproportionate impacts on vulnerable and historically marginalized communities.

Air pollution disrupts sleep. Poor air quality affects respiratory health and the central nervous system, while global warming’s nighttime warmth additionally interferes with the body’s circadian thermoregulation.

In San Francisco, New York, and London, public transportation lowers greenhouse gases and other pollutants, improving urban air quality and supporting public health.

Electric Vehicles eliminate tailpipe air pollution but still produce some emissions from wear, charging, and manufacturing. Cleaner energy and battery recycling help reduce EV air pollution.

Ambient and indoor air pollution come from different sources but often mix, exposing people to harmful pollutants like particulate matter, and contributing to long-term health and environmental problems.

Air pollution has changed over time, with sources evolving from wood burning and smelting to widespread fossil fuel use, industrial emissions, and intensified wildfires.

Wildfire smoke contains a complex mix of harmful pollutants, such as ozone precursors, carbon monoxide, and particulate matter like PM2.5 and black carbon. These pollutants can affect health and travel far from the fire source.

Air pollution affects millions every year, but there are simple, effective ways to protect yourself, especially during events like wildfires. Learn how to read the AQI, reduce exposure, and improve indoor air quality.
