The United States currently has modest levels of air pollution after decades of clean air actions. Dr Colette Heald, an atmospheric chemist at the Massachusetts Institute of Technology, speaks to Nature Geoscience about air pollution control in the US, and the challenges and opportunities faced under...

Air pollution is one of the leading causes of health complications and mortality worldwide, especially affecting lower-income groups, who tend to be more exposed and vulnerable. This study documents the relationship between ambient air pollution exposure and poverty in 211 countries and territories. ...

The average annual concentration of particulate matter (PM2.5) pollution in the United States stood at 7.8 micrograms per cubic meter (µg/m3) in 2022.
An interactive map of particle pollution levels from The Associated Press, based onNOAA, EPA and other data, showed a large area of red, indicating an "unhealthy" Air Quality Index, over northwestern New York and Toronto. There were also some red spots in the Midwest, while further north in...
Air pollution, release into the atmosphere of various gases, finely divided solids, or finely dispersed liquid aerosols at rates that exceed the natural capacity of the environment to dissipate and dilute or absorb them. High concentrations can cause und
In the United States, multiple studies have found that people of color have been systematically exposed to higher levels of air pollution (Colmer et al., 2020; Liu et al., 2021; Tessum et al., 2021). These racial disparities are not only found across different income levels, urbanicity ...
In subject area:Engineering Indoor air pollution is characterized by a large variability in the concentrations of pollutants among different indoor environments and depends on factors such as the emission characteristics of the sources, the behavior of the office occupants, and the microclimatic and ven...
Exposure to air pollution may be tied to the risk of developing depression later in life, a large new study finds. Scientists are finding more and more evidence that people who live in polluted areas have a higher risk of depression than those who live with cleaner air. But this study publ...
