Pakistan has been declared as the most polluted country in the world. The level of fine particulate matter PM2.5 in the country’s air is 13 times higher than the safe limit set by the World Health Organization.
According to the limit set by the World Health Organization, the air of the region is considered healthy if the PM2.5 value in the air is less than 5 micrograms per cubic meter. Only 13 countries in the world have been able to maintain this standard. The remaining 130 countries failed to meet this standard. Maharashtra’s Loni has emerged as the most polluted city in the world. The average level of PM2.5 in this city was 112.5 micrograms. Which is several times more than normal.
The second most polluted city is Hotan in China’s Xinjiang province. Air quality here is 109.6 micrograms. According to the report, the world’s 25 most polluted cities are all located in India, Pakistan and China. But the 13 countries that the agency says have healthy air quality are Australia, Iceland, Estonia and Panama. Countries such as Laos, Cambodia and Indonesia have made significant improvements compared to 2024.
