Delhi Air Quality Hits 'Moderate' Level, But Toxic Foam Chokes Yamuna
Delhi's air quality remains 'moderate' with an AQI of 168, but toxic white foam resurfaces on the Yamuna River near Kalindi Kunj.
The national capital is currently grappling with a dual environmental crisis. While the Delhi air quality AQI showed a slight shift on Tuesday morning, the city's lifeline, the Yamuna River, has once again been blanketed in thick, toxic white foam, raising serious concerns about the state of the city's ecology.
Air Quality Index: A Mixed Bag for Delhi-NCR
According to the Central Pollution Control Board (CPCB), Delhi recorded an Air Quality Index (AQI) of 168 at 8 am on Tuesday. This places the city in the 'moderate' category. This follows a similar trend from Monday, where the AQI was recorded at 164 at 7 am, suggesting a marginal improvement compared to the previous week.
However, the "moderate" average hides a harsher reality in several pockets of the city. Multiple areas continue to breathe "poor" quality air, with the following readings recorded:
- Jahangirpuri: 251
- Rohini: 237
- R K Puram: 234
- Dwarka-Sector 8: 223
- Bawana: 216
- IIT Delhi: 214
- IGI Airport (T3): 211
- Punjabi Bagh: 200
On a slightly more positive note, areas such as Chandni Chowk (198), Alipur (197), Patparganj (195), Anand Vihar (175), IGNOU Maidan Garhi (150), JNU (146), and NIH Narela (129) remained within the 'moderate' bracket. In the neighboring regions, Noida and Greater Noida recorded AQIs of 143 and 156 respectively, both falling under the 'moderate' category.
Fighting the Dust
To combat the rising levels of dust pollution, authorities have deployed anti-smog guns across various Delhi roads, spraying water to settle particulate matter and keep the air breathable.
Toxic Foam Returns to the Yamuna
While the air shows marginal improvement, the water quality of the Yamuna River has taken a visible dip. Massive blankets of toxic white foam have resurfaced near Kalindi Kunj, creating a stark and alarming visual of the river's pollution levels.
The timing of this resurgence is particularly poignant. The foam reappeared just days after Delhi Chief Minister Rekha Gupta praised the government's initiatives to restore the river. The Chief Minister had previously described the launch of mega infrastructure projects, valued at approximately ₹9,000 crore, as a "joyful day" for the people of Delhi.
Understanding the AQI Scale
To put these numbers into perspective, the CPCB uses the following guidelines to categorize air quality:
- 0 - 50: Good
- 51 - 100: Satisfactory
- 101 - 200: Moderate
- 201 - 300: Poor
- 301 - 400: Very Poor
- 401 - 500: Severe
For comparison, Mumbai's air quality remains significantly better, recording an AQI of 98, which falls under the 'Satisfactory' category, though the Kalanagar area there touched 139, moving into the 'moderate' zone.
