IQAira Swiss company specializing in the development of air quality control technologies published on its website air quality index by country in 2022ranking them from worst to best.
The list has been developed taking into account concentration of PM2.5 particles (particulate matter including organic chemicals, dust, soot and metals)and which are used for determine the levels of pollution it representsgenerating an average annual value, which can then be averaged over a certain period of time.
The ranking also includes subclassification which indicates how much higher the particle concentration is than recommended World Health Organizationand distributed as follows:
0-5 > complies with WHO recommendations
5.1-10 > 1-2 times higher
10.1-15 > 2-3 times higher
15.1-25 > 3-5 times higher
25.1-35 > 5-7 times higher
35.1-50 > 7-10 times higher
over 50 > more than 10 times higher
He first place from the list matches Chadin Africa, which averaged 89.7 PM2.5 per year in 2022, well above WHO recommendations.
They are followed in the rankings Iraq (80.1), Pakistan (70.9), Bahrain (66.6) and Bangladesh (65.8) closing the first five; Bye Burkina Faso (63) Kuwait (55.6) and India (53.3), – the rest of the cities, the index of which is ten times higher than the one set as optimal.
World, Mexico is in position number 49ranked in 2022 19.5, which is 3-5 times higher than the WHO recommendations, but does not reach critical levels. At the continental level, the country ranks third with Peru (23.5) taking first place and Chile (22.2) second.
Inside, the highest concentration of PM2.5 particles was found in metepec (36.1) and xonacatlán (28.5), both in Mexico State, Guadalajara (26.7), Jalisco and San Miguel (26.2).
mexico cityoverall occupies eighth place from 22.1 on average, and delegations Alvaro Obregon, Benedict Juarez And coyoacán It was they who had the greatest influence on the classification.
At the end of July, experts from National Autonomous University of Mexico (UNAM) warned that in our country, poor air quality is a problemespecially in urban areas where population, vehicle fleet and industry are increasing, especially outside of major metropolitan areas.
“Air quality continues to be one of the important topics for analysis. ICAyCC experts who are working hard to have forecasting capabilities, climate change scenarios, warnings and prevention, mitigation and adaptation measures,” said the director of this academic institution, Jorge Zavala Hidalgo, who moderated the Future of Air Quality dialogue table .
Also, ICAyCC researcher Graciela Binimelis de Raga recalled that in 2019 99 percent of the world’s populationHe lived in places where particulate matter emissions guidelines PM 2.5 has not been fulfilled.
Binimelis de Raga assured that global progress in terms of action reduce air pollution, but most still have a long way to go to breathe clean air. “There are still many countries in the world that don’t even have air quality monitoring networks.”
poor quality only one of the manifestations of environmental degradation, which is combined with other situations such as climate change and challenges in time and space.
