Air pollution is the largest environmental risk factor for disease and premature death [5] [14] and the fourth largest risk factor overall for human health. [15] Air pollution causes the premature deaths of around 7 million people worldwide each year, [5] or a global mean loss of life expectancy (LLE) of 2.9 years, [16] and there has been no ...

Air pollution is the introduction of chemicals, particulate matter, or biological materials into the atmosphere that cause harm or discomfort to humans or other living organisms, or damage ecosystems.

Diseases caused by pollution, lead to the chronic illness and deaths of about 8.4 million people each year. However, pollution receives a fraction of the interest from the global community. [1] This is in part because pollution causes so many diseases that it is often difficult to draw a straight line between cause and effect.
The health alert Saturday impacted millions of people, including across Rockland and Westchester counties, as the levels of pollution, either ozone or fine particulate matter (PM2.5), exceeded an ...
The U.S. also saw an uptick in air pollution, climbing from a nationwide average of 8.9 µg/m3 in 2022 to 9.1 in 2023, with the southward-drifting smoke from Canada’s wildfires partly to blame.
Air pollution is caused predominantly by burning fossil fuels, cars, and much more. [4] Natural sources of air pollution include forest fires, volcanic eruptions, wind erosion, pollen dispersal, evaporation of organic compounds, and natural radioactivity. These natural sources of pollution often soon disperse and thin settling near their locale.
The World Health Organization guidelines were most recently updated in 2021. [1] The guidelines offer guidance about these air pollutants: particulate matter (PM), ozone (O 3), nitrogen dioxide (NO 2), sulfur dioxide (SO 2) and carbon monoxide (CO). [2] The WHO first released the air quality guidelines in 1987, then updated them in 1997. [2]
