Delhi's Toxic Air Crisis: Why AQI at 318 Poses a Severe Health Threat

Delhi woke up to another day of hazardous air, with the overall AQI stuck in the 'very poor' category at 318. A thick blanket of smog made landmarks like India Gate barely visible and reduced visibility across the city. Specific monitoring stations, including ITO and Dwarka, reported even higher pollution levels, highlighting the widespread nature of the crisis. The Central Pollution Control Board warns that this level of pollution poses respiratory risks even to otherwise healthy individuals.

Delhi's air quality remains in 'very poor' category, AQI recorded at 318

New Delhi, December 8

The air quality in the national capital remained in the 'very poor' category on Monday morning as Delhi's overall Air Quality Index (AQI) reading stood at 318, as of 7 am, according to the Central Pollution Control Board (CPCB).

A thick layer of smog engulfed several areas across the state, with little to no improvement in the toxic air.

Several areas, including Anand Vihar, India Gate, Dwarka and ITO, reported thick haze early this morning, with visibility remaining significantly reduced. According to CPCB, many regions of the National Capital fell into the 'very poor' category.

The Air Quality Index around the ITO area is 354, categorised as 'Very Poor'.

At the same time, India Gate and Kartavya Path were barely visible this morning, shrouded by a thick layer of smog, as the air quality in the national capital remained hazardous. The toxic air persisted a day after Delhi recorded an AQI of 397, also in the 'very poor' range.

Several other key stations, including Ashok Vihar (338), Bawana (368), Burari (327), Chandani Chowk (321), and Dwarka (325), remained in the "very poor" category, highlighting the widespread nature of pollution across Delhi.

According to AQI categorisation, 0-50 is 'good', 51-100 'satisfactory', 101-200 'moderate', 201-300 'poor', 301-400 'very poor', and 401-500 'severe'.

According to CPCB, the AQI, which ranges from 0 to 500, is divided into six categories, each reflecting the level of pollution and associated health risks.

An AQI between 0 and 50 is classified as "Good", indicating minimal or no health impact. AQI levels from 51 to 100 fall into the "Satisfactory" category, where air quality remains acceptable, though sensitive groups such as children, the elderly, and those with respiratory issues may experience slight discomfort.

The "Moderate" category, ranging from 101 to 200, signals increasing pollution levels that can trigger breathing difficulties among people with asthma, lung conditions, or heart diseases.

An AQI between 201 and 300 is considered "Poor", a range in which prolonged exposure can cause breathing discomfort to most people, not just those with pre-existing health issues.

This level has become increasingly common in several parts of the capital during winter.

Levels between 301 and 400 are marked as "Very Poor", posing a risk of respiratory illnesses even to healthy individuals when exposure continues for long periods. The most hazardous category, "Severe," includes AQI values from 401 to 500. At this stage, air quality becomes dangerous for everyone.

Living in Dwarka, I can barely see the building across the street. The government needs to strictly enforce the ban on stubble burning in neighbouring states. It's not just a Delhi problem, it's a regional crisis.

While the government must act, we citizens also have a role. Can we commit to using public transport more? The number of private vehicles on the road is staggering. Small steps from all of us can make a difference.

As an expat living here, the air quality is a major concern for my family's health. We've invested in multiple air purifiers, but it feels like a band-aid solution. The data is alarming - 318 AQI is not just "very poor", it's a public health emergency.

The odd-even scheme is back, but is it really effective? Industries and construction dust are major contributors too. Need a comprehensive policy that addresses all sources, not just political quick-fixes before elections.

My elderly parents in Chandni Chowk are suffering terribly. They can't even go for their morning walk anymore. This is affecting the quality of life for millions. Where is the urgency from our leaders? 🤧
