It is no secret that the pollution levels in a lot of cities in India have reached a near-toxic level due to climate change, human activities and other factors. Now, according to a recent study, some of the most developed cities in India are also the most polluted in the world.
According to a report called the Air Quality and Health in Cities, released by US-based Health Effects Institute last week, India’s capital city New Delhi is the most polluted city in the entire world, with West Bengal’s Kolkata bagging the second spot.
The report released by the HEI stated that urban cities such as Delhi and Kolkata have higher levels of pollution due to increased population, which is caused by growing job opportunities and better lifestyles offered by developing infrastructure.
While Delhi and Kolkata were on the first and second spot on the list according to the report, the third spot was bagged by Kano city in Nigeria while Peru’s Lima stood at the fourth spot. Maharashtra’s Mumbai was also mentioned in the list.
The analysis of the most polluted cities in the entire world was done by the institute on the basis of the quantity of two of the most harmful pollutants in the atmosphere - fine particulate matter (PM2.5) and nitrogen dioxide (NO 2).
