In European countries, air quality at or above 10 micrograms per cubic meter of air (μg/m 3) for PM 2.5 increases the all-causes daily mortality rate by 0.2-0.6% and the cardiopulmonary mortality rate by 6-13%. [35] Worldwide, PM 10 concentrations of 70 μg/m 3 and PM 2.5 concentrations of 35 μg/m 3 have been shown to increase long-term ...
Maternal PM 2.5 exposure during pregnancy is also associated with high blood pressure in children. [218] Inhalation of PM 2.5 – PM 10 is associated with elevated risk of adverse pregnancy outcomes, such as low birth weight. [219] Exposure to PM 2.5 has been associated with greater reductions in birth weight than exposure to PM 10. [220]
The largest cause of air pollution is fossil fuel combustion [137] – mostly the production and use of cars, electricity production, and heating. [138] There are estimated 4.5 million annual premature deaths worldwide due to pollutants released by high-emission power stations and vehicle exhausts. [139]
The highest AQI in India was recorded in New Delhi on 18th November 2024 with it being 1,081 and the concentration of PM2.5 - particulate matter measuring 2.5 microns or less in diameter that can be carried into lungs, causing deadly diseases and cardiac issues. Expected to soar even higher later or next year.
Air pollution is among the biggest health problems of modern industrial society and is responsible for more than 10 percent of all deaths worldwide (nearly 4.5 million premature deaths in 2019), according to The Lancet. Air pollution can affect nearly every organ and system of the body, negatively affecting nature and humans alike.
Chromosomal damage is high among African American children and their mothers from Oakland, California who are exposed to traffic and regional ozone levels. [38] Coronary heart disease has been one of the leading cause of death in ethnic groups. [39] One study found that PM2.5 exposure
A study published in 2022 in GeoHealth concluded that energy-related fossil fuel emissions in the United States cause 46,900–59,400 premature deaths each year and PM2.5-related illness and death costs the nation $537–$678 billion annually. [52] In the US, deaths caused by coal pollution were highest in 1999, but decreased sharply after 2007.
In 2019, India launched 'The National Clean Air Programme' with tentative national target of 20%-30% reduction in PM2.5 and PM10 concentrations by 2024, considering 2017 as the base year for comparison. It will be rolled out in 102 cities that are considered to have air quality worse than the National Ambient Air Quality Standards. [15]
