Delhi Chokes as Air Quality Plummets to Severe Category
The national capital woke up to another day of hazardous air on Tuesday as Delhi's average Air Quality Index (AQI) skyrocketed to 425, pushing the city into the 'severe' pollution category. This alarming spike represents a significant deterioration from Monday's reading of 362, marking one of the worst air quality episodes this season.
Weather Conditions Worsen Pollution Crisis
Meteorological factors have played a crucial role in this rapid decline of air quality. Calm wind conditions and unfavourable weather patterns have trapped pollutants close to the ground, preventing their dispersion. The virtual absence of wind movement has created a toxic blanket over the city, with particulate matter concentrations reaching dangerous levels.
The sharp increase from 362 to 425 within just 24 hours underscores how quickly air quality can deteriorate under adverse weather conditions. This dramatic worsening has triggered immediate regulatory action from authorities.
GRAP-III Emergency Measures Implemented
In response to the escalating pollution crisis, authorities have imposed Stage III of the Graded Response Action Plan (GRAP). This emergency protocol activates several stringent measures aimed at controlling pollution sources and protecting public health.
The GRAP-III restrictions include:
- Ban on construction and demolition activities
- Restrictions on the operation of certain vehicle categories
- Enhanced pollution control measures at industrial units
- Intensified public transport services
These measures are designed to immediately reduce emission sources and prevent further deterioration of air quality during this critical period.
Health Advisories and Public Response
Medical experts have issued urgent health advisories, particularly for vulnerable groups including children, elderly citizens, and individuals with pre-existing respiratory conditions. Doctors recommend:
- Minimizing outdoor activities
- Using N95 masks when going outside
- Keeping windows closed in homes and vehicles
- Using air purifiers indoors
The implementation of GRAP-III comes as Delhi faces its annual battle with winter pollution, characterized by a combination of local emissions and regional factors that create perfect conditions for air quality crises.
Authorities continue to monitor the situation closely, with the possibility of implementing even stricter measures if the AQI fails to improve in the coming days.
