'Poison In The Air': Richa Chadha's Alarm As Mumbai's AQI 'Beats' Delhi's, BMC In Line Of Fire

Mumbai has long benefited from its coastal location, with winds from the Arabian Sea helping disperse pollutants generated by traffic, construction and other urban activities. But as the city’s air quality deteriorates, that natural advantage appears less effective, raising questions about what is driving the pollution and whether monitoring systems are accurately capturing its extent.

The contrast with Delhi is striking. While winter pollution in the national capital is associated with weak winds, farm fires and emissions accumulating close to the ground, Mumbai is also experiencing poor air quality despite its proximity to the sea. Sluggish winds, construction dust, vehicle exhaust, open waste burning, agricultural fires and festival-season firecrackers are among the factors experts have identified.

The concern is no longer limited to how polluted Mumbai’s air has become. Questions are also being raised about whether the readings displayed at some construction sites accurately reflect conditions on the ground. Recent reports have highlighted substantial differences between nearby sensors, even as the Brihanmumbai Municipal Corporation (BMC) prepares to use artificial intelligence to monitor thousands of devices.
