Air Pollution Concerns Rise in Delhi-NCR

As Diwali approaches, air pollution levels in Delhi-NCR have escalated, raising alarm among residents. The air quality in the capital is deteriorating, with several areas recording an Air Quality Index (AQI) in the severe category. On November 3, the average AQI in Delhi was approximately 331, while in Jahangirpuri, it soared to 449, indicating a troubling trend with little relief in sight.

Severe AQI Levels Recorded

Numerous regions in Delhi are experiencing alarming pollution levels, classified as severe. Jahangirpuri reported an AQI of 449, followed by Rohini at 429, Punjabi Bagh at 424, Alipur at 413, and Vivek Vihar at 410. Additionally, Narela recorded an AQI of 406, while Sector 62 in Noida reached 404.

Implementation of GRAP-2

In response to the rising pollution, the Commission for Air Quality Management (CAQM) has activated the second phase of the Graded Response Action Plan (GRAP) in Delhi-NCR. This phase includes mechanical street cleaning, water spraying, and targeted campaigns in pollution hotspots. Inspections will also be intensified to ensure compliance with dust control regulations at construction sites.

Moreover, measures such as increasing parking fees to discourage private vehicle use and promoting public transport are being implemented. Residents are also encouraged to consider work-from-home options where feasible.

Factors Contributing to Air Quality Decline

Adverse weather conditions are significantly contributing to the worsening air quality. The slow wind speeds are causing pollutant particles to accumulate in the atmosphere. Emissions from vehicles, dust from construction activities, and pollution from stubble burning are further degrading air quality.

Understanding AQI Categories

According to the Central Pollution Control Board (CPCB), an AQI between 301 and 400 is classified as 'very poor,' while an AQI from 401 to 500 falls into the 'severe' category. Air at severe levels can be harmful to health, necessitating extra precautions for children and the elderly.

With Diwali approaching, concerns about pollution are intensifying. The air quality in the coming days will depend on weather conditions and pollution control measures.
