As of April 1, air pollution levels in most Ukrainian cities are rated as moderate. However, in some areas of large urban centers, pollution levels exceed standards by a significant margin, which may pose a risk to people with respiratory and cardiovascular conditions.
This is evidenced by data from the international monitoring platform IQAir.
Air pollution in Kyiv is currently moderate. The concentration of PM2.5 fine particulate matter is 12.9 mg/m³, which is more than twice the World Health Organization standard of 5.5 mg/m³.

Overall, in the ranking of the world's most polluted cities, the Ukrainian capital on April 1 ranks 43rd, between Skopje in North Macedonia and Singapore.
However, some monitoring stations report data indicating unhealthy air quality for sensitive population groups. The worst air quality is in Sofiivska Borshchahivka. There, the dust concentration reaches 38.6 mg/m3, which is seven times higher than the norm.
Monitoring stations in Dnipro, Kharkiv, and Odesa also show predominantly moderate pollution levels.
Although the air quality in Lviv is average, and one station even indicates safe air, the citywide dust level is 18.1 mg/m3, which is 3.3 times above the WHO standard.

EcoPolitic previously reported that Ukrainian scientists studied the impact of war on air quality. You can find more details in the article.
