When these small particles become suspended in the air, they can pose a risk to the health of those who breath in the contaminated air. There are many dust-producing activities across a broad range of industries, including agriculture, construction, forestry, and mining. As such, the nature of occupational dust exposures can vary greatly by ...
Air pollution hotspots are areas where air pollution emissions expose individuals to increased negative health effects. [272] They are particularly common in highly populated, urban areas, where there may be a combination of stationary sources (e.g. industrial facilities) and mobile sources (e.g. cars and trucks) of pollution.
This category includes hazardous air pollutants, as listed in Section 112 of the U.S. Clean Air Act (1970) and Clean Air Act (1990). The list can be found on Wikipedia at National Emissions Standards for Hazardous Air Pollutants, and on EPA at .
Environmental impact of fracking in the United States has been an issue of public concern, and includes the contamination of ground and surface water, methane emissions, [1] air pollution, migration of gases and fracking chemicals and radionuclides to the surface, the potential mishandling of solid waste, drill cuttings, increased seismicity and associated effects on human and ecosystem health.
The international pictogram for environmental hazards. Environmental hazards are hazards that affect biomes or ecosystems. [1] Well known examples include oil spills, water pollution, slash and burn deforestation, air pollution, ground fissures, [2] and build-up of atmospheric carbon dioxide. [3]
The risk of air pollution is determined by the pollutant's hazard and the amount of exposure that affects a person. [36] For example, a child who plays outdoor sports will have a higher likelihood of outdoor air pollution exposure than an adult who tends to spend more time indoors, whether at work or elsewhere.

US counties that are designated "nonattainment" for the Clean Air Act's NAAQS, as of September 30, 2017. The U.S. National Ambient Air Quality Standards (NAAQS, pronounced / ˈ n æ k s / naks) are limits on atmospheric concentration of six pollutants that cause smog, acid rain, and other health hazards.

After a steady 23-year decline in US pollution levels through 2017, the American Lung Association's State of the Air 2022 report found a sharp uptick in pollution over the past five years. [ 93 ] According to the American Lung Association's State of the Air 2024 report, California retains its position of being the state with the most metro ...
