Particulate matter causes health problems for those who inhale the fine droplets and particles, but the chemical composition of the mixture matters—and can vary widely across space and time.

The previous annual standard for particulate matter was 12 micrograms per cubic meter of air. Under this new rule, the EPA is lowering the annual standard to 9 micrograms per cubic meter.

The NASEM shall convene a committee of scientific experts to consider the state-of the-science on the health risks of exposure to fine particulate matter (PM2.5) indoors and engineering solutions and ...

Pan-frying, stir-frying, deep-frying, and boiling produce particulate matter and volatile organic compounds that can harm your health. Here's what to do instead.

Southern California has long struggled to meet federal air pollution standards. Now, the EPA wants to impose even higher requirements for particulate matter.

Fine particulate matter, or PM2.5, is a category of tiny airborne particles produced by power plants, forest fires, and industrial factories, among other sources.
