India's Loni Named World's Most Polluted City Loni, a city in the northern state of Uttar Pradesh, has been named the most polluted city globally in 2025, according to a report by the Swiss air quality monitoring firm IQAir. The city recorded an average PM2.5 pollution level of 112.5 micrograms per cubic meter, surpassing other major urban centers. The report highlights the severe air quality challenges faced by Loni, which is part of a broader trend of pollution in Indian cities. The findings place Loni among the top four most polluted cities worldwide, alongside three other Indian cities, including New Delhi. This ranking underscores the urgent need for improved environmental policies and stricter enforcement of pollution control measures. The report also notes that PM2.5 levels in these cities remain significantly higher than the World Health Organization’s recommended limits, posing serious health risks to residents. The pollution crisis in Loni is attributed to a combination of factors, including industrial emissions, vehicular exhaust, and seasonal agricultural burning in surrounding regions. The city’s location in a densely populated area exacerbates the problem, as pollutants accumulate and spread across the region. Experts warn that prolonged exposure to such high levels of particulate matter can lead to respiratory diseases, cardiovascular issues, and other health complications. The IQAir report also highlights the broader context of air pollution in India, where several cities consistently rank among the world’s most polluted. While some cities have made progress in reducing emissions through policy interventions, others continue to struggle with outdated infrastructure and limited enforcement of environmental regulations.#uttar_pradesh #new_delhi #iqair #loni #byrnihat
