Annual report analyzes data data over 40,000 Air quality tracking stations 8,954 locations during 138 countries, provinces and regions, according to IQAIR, Switzerland-based air technology company.
The rankings is the average of the concentrated microgramms of a pollutant air pollutant per cubic air. The World Health Organization recommends 5 micrograms for each cubic metro.
Which countries have the lowest quality of air?
Worldwide, countries with the worst quality of air were Chad, Bangladesh, Pakistan, the Democratic Republic of the Congo. Chad 91.5 per cubic contaminant pollutant, said Iqair – more than 18 times What does it recommend.

The whole African continent said about 3.7 million people only said Moniotical station, Iqair said, which can cause incorrect data in the region.
What do US parts have the best and worst quality of air?
Most of the universities in the United States had 5.1 and 15 pollution micrograms for each cubic air, according to IQAIR. In several cities, especially on the western coast, in England and southwestern, 0 to 5 pollution micrograms were micrograms per cubic metro, who meets the instructions.
The main city with the worst air pollution was Los Angeles, California. The small town of Ontario, California, had the city pollution, said the report.

Air pollution “It is a critical threat to human health and environmental stability, IQAIR CEO FRANK HAMMES said in a news version Announces the discovery of the report.
It is eighty-nine percent of the world’s population living in sites that do not meet the level of the recommended air quality guide. Air pollution is a global risk factor for death. In 2021, 8.1 million deaths from around the world could be attributed Air pollutionSaid Iqair.
Exposure of concentrated microgramrams of a air pollutant caused about 58% of these deaths, Iqair said. The exposure to pollutants can provide and increase health conditions including asthma, cancer, blow and lung diseases. Children can have problems with respiratory and developmental health.
