Air pollution: No country adheres to WHO limit values

Air quality remains poor worldwide. According to the World Health Organization 2021, no country has been able to meet the maximum values ​​of air pollution. In some cities it has been exceeded tenfold.

Not a single country was able to meet international boundary air quality values ​​last year. This was announced by the World Health Organization. This results from data in 6,475 cities. In some areas, air pollution has increased again after the stalemate associated with the epidemic.

The World Health Organization recommends that the concentration of small and hazardous airborne particles do not exceed five micrograms per cubic meter. Only 3.4 percent of the cities surveyed met the standard in 2021. Air pollution levels in 93 cities were measured at ten times the maximum recommended levels.

Progress in China, regression in India

“There are many countries that are making great strides in reducing the size of the disease,” said WHO expert Kristi Schroeder. “China started at very high levels, and has continued to decline over time.”

In contrast, air quality in India has deteriorated. New Delhi remained the most polluted capital in the world. Bangladesh was the most polluted country, followed by Chad.
