In a big shift for Delhi's air quality this monsoon, five of Delhi's 13 pollution hotspots recorded 'Good' Air Quality Index (AQI) readings on Thursday - a first for the month of July.
According to official Central Pollution Control Board (CPCB) data, Vivek Vihar registered an AQI of 35, followed by Dwarka (40), Jahangirpuri (47), Punjabi Bagh (48), and Rohini (50). The citywide average AQI stood at 59, making it the 15th straight day of 'Satisfactory' air.
Environment Minister Manjinder Singh Sirsa termed it "a historic milestone," attributing the improvement to sustained enforcement, cleaner roads, and public engagement.
"After years of struggling with high pollution, Delhi's air is seeing a meaningful shift. The hotspots have shown what's possible with focused action," Mr Sirsa said.
The air quality update coincided with Van Mahotsav 2025, observed with a mass plantation drive at Shastri Park City Forest. The campaign aligned with the central government's 'Ek Ped Maa Ke Naam' initiative and the Delhi government's plan to plant 70 lakh trees this year.
"Van Mahotsav has become a citizen-led movement," Mr Sirsa said. "Delhi's people are central to this green push."
According to the government, alongside the plantation drive, the city's pollution control measures and civic clean-up drives are ongoing. Over a 24-hour period between July 9-10, the following were reported:
11,283 MT of municipal waste cleared
2,281 MT of construction debris removed
6,497 km of roads swept
710 km of roads sprinkled with 352 KL of treated water
Legacy waste removal from Delhi's landfill sites also saw major progress:
Bhalaswa: 10,804 MT
Okhla: 6,507 MT
Ghazipur: 9,748 MT
Total cleared in 24 hours: 27,059 MT
Officials say the gains are part of the ongoing Environment Action Plan 2025, which focuses on dust control, mechanised sweeping, enforcement at construction sites, and real-time monitoring.
Delhi's cleaner air is a notable shift - but not a guarantee. While hotspot-level improvements show what's possible with focused action, the real challenge will be sustaining this progress beyond the monsoon.
The average daily microplastic exposure rose from 10.7 particles in the colder months to 21.1 in the hotter season, the study highlighted.
Monsoon ushers in respiratory trouble for many and pneumonia cases rise sharply, driven by damp air, viral spread, indoor pollutants, and rain-wetting. Children, elderly, and those with compromised immunity are most vulnerable.
Rain lashed several parts of Delhi and the surrounding National Capital Region (NCR) on Saturday evening. Areas including Lajpat Nagar, RK Puram, Lodhi Road, and Mandir Marg witnessed light showers.
In a bid to tackle one of the worst sources of air pollution, Delhi has begun testing retrofitting devices that promise to cut harmful emissions from heavy commercial vehicles by more than 70 per cent.
Delhi is gearing up to build one of India's most advanced e-waste processing facilities, and it's taking cues from Norway's cutting-edge model.

Friday November 08, 2024हमारी हवा जहरीली हो रही है. गुरुवार की शाम को जब मैं इस मुद्दे पर लिखने बैठी तो AQI लगातार 400 पार जाकर दम घोंट रहा था. बहुत लोगों को यह मामला बोरिंग लगे, लेकिन जब आप अपने साथ काम करने वालों को खांसते-हांफते देखते-सुनते हैं, तो चिंता होने लगती है. सुबह उठते ही दरवाजे खिड़कियां खोलने के लिए डॉक्टर मना कर रहे हैं. बड़े बुजुर्गों के लिए तो मॉर्निंग वॉक बाहर की दुनिया से सीधे संपर्क का ज़रिया है, लेकिन डॉक्टर इसकी भी मनाही कर रहे हैं.
