Mumbai’s Air Quality Index (AQI) stayed in the ‘moderate’ category on Wednesday morning, reflecting a minor improvement but signalling caution for residents. Early morning readings at 5:30 am indicated a slight dip from 143 to 138, according to officials monitoring the Air Quality Early Warning System. While the city remains within a manageable range, pockets such as Chembur and Bandra recorded the highest pollution levels, underlining the uneven distribution of air quality across the metropolitan region.
Experts point out that post-monsoon atmospheric conditions and vehicular emissions are contributing to rising particulate matter (PM) concentrations. Data from the monitoring authorities suggest that PM2.5 and PM10 levels have steadily increased as rainfall receded, creating a precursor for potential air quality deterioration in the coming months. “Winter winds in Mumbai tend to slow down, trapping pollutants in the urban atmosphere and often pushing AQI levels into the unhealthy range,” said an official from the city’s environmental monitoring agency. The uneven dispersion of pollutants is particularly visible in high-traffic and industrial hubs. Chembur, with its dense residential clusters and proximity to industrial activity, and Bandra, a major commercial and transport corridor, have consistently reported elevated particulate matter levels. Residents in these areas face increased exposure to pollutants, which can exacerbate respiratory conditions and heighten vulnerability among the elderly, children, and those with pre-existing health conditions.
Sustainable urban planning and stricter vehicular emission norms are increasingly critical as the city braces for winter. Officials highlighted that curbing traffic congestion, promoting electric public transport, and enforcing construction dust regulations can collectively improve Mumbai’s AQI. “Zero-emission zones, green buffer spaces, and public awareness campaigns are essential to maintaining air quality and ensuring equitable environmental benefits across all city neighbourhoods,” added an environmental policy expert. While the moderate AQI currently allows normal outdoor activity, the government and civic agencies are urging residents to adopt precautionary measures. Mask usage, minimizing outdoor exposure during peak traffic hours, and avoiding open burning are recommended to reduce personal exposure.
As Mumbai continues its rapid urban growth, maintaining a balance between development and environmental sustainability remains an urgent priority. Continuous monitoring, transparent reporting, and proactive policy enforcement will be crucial to safeguarding public health and fostering a cleaner, greener metropolitan ecosystem.
