In Mumbai, air pollution is worsening, especially because of dust from ongoing construction projects. Residents like Shabnam Abdul Gaffar Shah in Mankhurd are suffering with coughing and breathing problems caused by poor air quality. A study by Maharashtra Pollution Control Board found dust contributes 30% of harmful PM10 pollution in the city. The city’s air often exceeds safe levels of PM2.5 and PM10, partly due to traffic and winter air stagnation. Respirer Living Sciences reported a slight rise in PM2.5 levels from 2019 to 2024 and noted many 'moderate' to 'poor' air quality days during heavy construction times. In Wadala, near new infrastructure projects, thick dust affects vulnerable people like advocate Shweta Mehta's parents. Doctors see more patients with respiratory issues. Dr. Asmita Mahajan from Fortis Raheja Hospital says, "Children with asthma see an exacerbation of symptoms," and hospital admissions for lung problems have tripled. The Bombay High Court intervened in 2023, issuing 28 strict guidelines for construction sites, such as using air quality sensors and water sprinklers. Despite orders, only 400 of nearly 1,000 sites have installed sensors, many of which are non-functional, and are not linked to a central system. The court rejected excuses like volcanic ash and stressed the urgent need for a sustained pollution control plan. A new committee will report by December 15, 2025. BMC Commissioner Bhushan Gagrani launched Project MANAS with IIT Kanpur to improve air quality monitoring. However, experts say data alone is not enough without real action. Scientists suggest advanced pollution filters and purifiers but blame slow government action. Environmentalists noticed PM2.5 data vanished from the CPCB Sameer app in May 2025, sparking concerns about transparency. Officials say the CPCB controls this data. The BMC claims it is enforcing rules by issuing stop-work notices to 321 construction sites and deploying 94 squads to monitor guidelines. Yet experts remain skeptical of measures like mist spraying. Mumbai’s air pollution continues to harm public health, and authorities face pressure to act decisively to clear the city’s toxic air.
