The post-Diwali air quality analysis across Maharashtra reveals an alarming spike in pollution levels, with PM2.5 concentrations surging significantly in Mumbai, Pune, and Nagpur. This year, smaller cities such as Dhule, Nanded, and Pimpri-Chinchwad also recorded disturbing PM2.5 peaks, underscoring a pressing concern that extends beyond major metros. Data from Respirer Living Sciences’ AtlasAQ platform highlights a more than 50% surge in PM2.5 levels in several urban centres across the state between October 30 and November 1, coinciding with Diwali celebrations.
Mumbai witnessed PM2.5 levels climbing by 50.3%, with localities like Sewri and Malad West experiencing the most significant increases, marking a cumulative rise of over 100% in some areas. Pune followed suit, showing notable surges in pollution within Hadapsar and Shivajinagar, while Nagpur saw a staggering 80% increase in its PM2.5 levels in locations such as Ram Nagar and Ambazari. These increases emphasise the need for stringent air quality measures to tackle seasonal pollution, which has severe health implications for Maharashtra’s urban and semi-urban populations.
Tier II cities were notably impacted, with Dhule registering the highest PM2.5 level on November 1, reaching 137.25 µg/m³—far surpassing levels recorded in Mumbai. Nanded and Pimpri-Chinchwad closely followed with PM2.5 concentrations exceeding 125 µg/m³, while Ahmednagar and Parbhani also reported alarmingly high readings. Such statistics underline a broader, statewide concern that transcends traditional pollution hotspots, pointing to a pressing need for environmental vigilance and community-level intervention.
Sustainability and proactive measures are becoming imperative to address these annual pollution peaks. Unlike previous years, where larger metros bore the brunt, these recent trends in smaller cities highlight an urgent demand for localised air quality initiatives. By focusing on reducing emissions during high-risk periods, Maharashtra could mitigate the health risks faced by residents across the state, from metropolitan centres to emerging urban hubs. The findings underscore the critical role of sustainable urban planning, stricter pollution control protocols, and heightened public awareness to ensure a cleaner environment. Proactive measures taken now could safeguard not only urban dwellers but also the populations of smaller towns, making cleaner air accessible and sustainable for all Maharashtra residents.
