Will Beijing be removed from the list of most polluted cities in the world?

The generally poor air quality in Beijing’s Chinese capital has improved in recent years, leaving the city the list of the 200 most polluted cities in the world this year. Notwithstanding the good results, the current concentration of PM 2.5 particles is still four times above the ceiling set by the World Health Organization (WHO).

Air Visual, a subsidiary of the Swiss technology firm IQAir, announced days ago that Beijing is on track to reduce its concentration of PM 2.5, considered the deadliest pollutant by 20 percent this year.

The average hourly concentration of these particles in the smog-laden Chinese capital in the first eight months of this year was 42.6 micrograms per cubic meter, compared to 52.8 micrograms per cubic meter in the same period last year.

According to the report, the 10-year comparison will be even more striking. The average hourly concentration of PM 2.5 decreased by more than half between January and August 2019, as compared to the same period of 2009
