Warning to millions as toxic air lung-penetrating particles across 10 states
Toxic lung-penetrating air pollution particles have been detected across 10 U.S. states, including New York and California, posing health risks to millions of residents.
Background
- The article warns about dangerous levels of PM2.5 — microscopic particulate matter that is 2.5 micrometers or smaller, small enough to enter the lungs and bloodstream, causing serious health issues like heart attacks, strokes, and lung cancer.
- These particles come from sources like vehicle exhaust, power plants, wildfires, and industrial emissions.
- The warning covers 10 U.S. states where PM2.5 levels are especially high, including parts of California and New York.
- The U.S. Environmental Protection Agency (EPA) tightened its annual PM2.5 standard from 12 to 9 micrograms per cubic meter in early 2024, a move that placed more counties in violation.
- Air quality monitoring groups and public health researchers have raised concerns that many areas still fail to meet even the old standard, disproportionately affecting low-income and minority communities.
