Particulate Matter

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.

Cities around the world are improving air quality by introducing Low Emission Zones (LEZs), Ultra Low Emission Zones (ULEZs), and congestion pricing. From London to Warsaw to New York, these measures reduce vehicle emissions, ease traffic, and support public health.

Wildfires carry hidden costs that extend beyond immediate damage. They strain public health systems, disrupt employment, and drive up nearby housing costs. Proactive strategies can help reduce these long-term financial impacts.

Air pollution in the U.S. rises significantly during the Fourth of July due to fireworks, increased travel, and backyard grilling. Sustainable celebrations and air quality monitoring can help lessen the harmful impact.
