The state recorded a PM2.5 attraction of 14.9 micrograms per cubic meter, which is 3 times the World Health Organization recommended yearly line value. Pakistan ranked arsenic the astir polluted country, with a PM2.5 attraction of 67.3 micrograms per cubic meter.

The IQAir report draws connected information from 9,446 cities spanning 143 countries, regions, and territories. More than 40,000 regulatory monitoring stations and low-cost sensors contributed to the findings. Government agencies, universities, non-profit organizations, backstage companies, and national scientists worldwide each participated arsenic information contributors.

Bosnia and Herzegovina recorded the highest contamination levels astatine 23.4 μg/m³, followed by North Macedonia astatine 21.2 μg/m³ and Serbia astatine 19.8 μg/m³.

Greece’s planetary contamination rankings awesome 1 of Europe’s sharpest rises

Greece besides recorded 1 of the sharpest nationalist increases connected the continent. Its yearly mean climbed from 11.5 μg/m³ to 14.9 μg/m³, a emergence of much than 30%.

Lamia, successful Central Greece, ranked arsenic the country’s astir polluted metropolis with 20.9 micrograms. Agios Nikolaos, located connected the land of Crete, recorded the cleanest aerial successful the state at 5.8 micrograms.

Multiple sources thrust mediocre aerial prime crossed Greece. Vehicle emissions stay a superior contributor. Coal-fired powerfulness plants, concern zones, and manufacturing facilities adhd substantially to the contamination burden.

Wood burning for heating, a signifier that expanded during the country’s indebtedness crisis, continues arsenic a important wintertime source. Forest fires person besides triggered notable contamination spikes historically.

Seasonal patterns and wellness risks for residents

Pollution follows a wide seasonal pattern. Winter months bring the highest PM2.5 concentrations arsenic heating request rises and acold aerial traps pollutants adjacent the surface. Air prime improves considerably from outpouring done aboriginal autumn.

Greece’s broader presumption successful planetary contamination rankings carries nonstop health implications for residents. Researchers subordinate semipermanent vulnerability to good particulate substance with respiratory diseases, including asthma, bronchitis, emphysema, and lung cancer.
