Loni Identified as World’s Most Polluted City

The city of Loni, India, is facing a severe air pollution crisis, earning the designation of having the world’s worst air quality. A toxic combination of fumes from factories, vehicle exhaust, and construction dust is making breathing a challenge for its 700,000 residents.

The Impact on Residents

“Forget coughing, even breathing is difficult here,” said Manoj Kumar, a 45-year-old e-rickshaw driver and lifelong resident of Loni. Many residents, like Mohammad Mohmin Khan, are forced to wear masks when venturing outdoors due to the inescapable pollution and poorly maintained roads.

PM2.5 Levels and Health Risks

IQ Air’s analysis determined Loni’s average PM2.5 concentration was 112.5 last year – 22 times the World Health Organization’s safe limit. PM2.5 particulates are particularly dangerous as they can enter the bloodstream and have been linked to asthma, heart and lung disease, cancer, and cognitive impairment in children.

Rising Respiratory Illnesses

Dr. Anil Singh, a local clinic operator, has observed a significant increase in respiratory issues among his patients over the past five years. He noted a rise in young children presenting with early asthma symptoms, attributing it to environmental exposure.

National Pollution Trends

According to IQ Air, three of the world’s top five most polluted cities in 2025 were located in India. Vehicle and industrial emissions, crop residue burning, and construction dust are major contributors to the country’s pollution problems.

Seasonal Pollution Spikes

Loni, along with other cities in northern India, experiences a dramatic increase in pollution levels from December to January. A phenomenon called temperature inversion traps hazardous air near the ground, exacerbating the problem.

Government Efforts and Challenges

India launched its Clean Air Program in 2019, aiming to reduce particulate matter concentration by 40% by 2025-26. Measures include stricter regulations on coal-based power plants, air monitoring systems, and bans on biomass burning. While some cities have shown improvement, experts cite a lack of enforcement and coordination as hindering progress.

Resident Concerns

Khushi Feroze, a mother in Loni, shared that her three-year-old son frequently suffers from allergies, coughs, and stomach infections due to the pollution. Residents express a desire for cleaner air, noting a significant improvement in air quality when traveling outside of Loni. “We definitely feel much better when we leave here,” Feroze said.
