This list contains the top 500 cities by PM2.5 annual mean concentration measurement as documented by the World Health Organization covering the period from 2010 to 2022. The January 2024 version of the WHO database contains results of ambient (outdoor) air pollution monitoring from almost 5,390 towns and cities in 63 countries.
All data are valid for the year 2022 and are taken from the Air Quality Life Index (AQLI) of the University of Chicago.In addition to particulate matter pollution, the modeled potential loss of life expectancy of the population due to particulate matter pollution is given.
PM 2.5 AQI of US monitors, calculated utilizing NowCast, courtesy US EPA PM2.5 AQI map, calculated utilizing NowCast, courtesy US EPA. The PM (particulate matter) NowCast is a weighted average of hourly air monitoring data used by the United States Environmental Protection Agency (USEPA) for real-time reporting of the Air Quality Index (AQI) for PM (PM 10 - particles less than 10 micrometers ...
Air quality in Los Angeles was at "moderate" levels on Thursday morning, as judged by the EPA's Air Quality Index rating system. Moderate air quality is between 51 and 100, or in the yellow band ...
The most commonly used air quality index in the UK is the Daily Air Quality Index recommended by the Committee on the Medical Effects of Air Pollutants (COMEAP). [39] This index has ten points, which are further grouped into four bands: low, moderate, high and very high. Each of the bands comes with advice for at-risk groups and the general ...
Thus an AQI of 100 does not mean twice the pollution of AQI at 50, nor does it mean twice as harmful. While an AQI of 50 from day 1 to 182 and AQI of 100 from day 183 to 365 does provide an annual average of 75, it does not mean the pollution is acceptable even if the benchmark of 100 is deemed safe. This is because the benchmark is a 24-hour ...
The majority of CO emitted into the ambient air is from mobile sources. The EPA has reviewed and assessed the current scientific literature with respect to CO in 1979, 1984, 1991, and 1994. [11] After the review in 1984 the EPA decided to remove the secondary standard for CO due to lack of significant evidence of the adverse environmental impacts.
In the wake of the 1965 Palm Sunday tornado outbreak, one of the key recommendations from the U.S. Weather Bureau's storm survey team, was the establishment of a nationwide radio network that could be used to broadcast weather warnings to the general public, hospitals, key institutions, news media, schools, and the public safety community.
