Delhi’s Air Quality Deteriorates Again
Delhi’s air quality, which showed some improvement earlier today, has once again dipped into the ‘Severe’ category. By 6 PM, the 24-hour average Air Quality Index (AQI) surged past the 400 mark, sparking serious concerns for residents. Out of the city’s 39 monitoring stations, 19 reported AQI levels in the “Severe” category, with Jahangirpuri recording the highest at 445.
Why is Delhi’s Air Quality Declining?
The worsening air quality is attributed to a mix of factors including:
- Vehicular Emissions: High traffic volumes in Delhi-NCR significantly contribute to pollution levels.
- Farm Fires: Stubble burning in neighboring states exacerbates the smog problem.
- Weather Conditions: Low wind speeds and temperature inversions trap pollutants close to the ground.
The Health Impact of Poor Air Quality
With AQI levels consistently in the ‘Severe’ range, the health implications are dire:
- Respiratory Issues: A survey by LocalCircles revealed that 75% of families in Delhi reported at least one member suffering from conditions like sore throat or cough.
- Chronic Diseases: Long-term exposure increases the risk of asthma, bronchitis, and even cardiovascular conditions.
- Children and Elderly at Risk: Vulnerable groups, including children and senior citizens, face heightened risks.
Graded Response Action Plan (GRAP) Measures
To combat the alarming pollution levels, Delhi has implemented Stage IV of the Graded Response Action Plan (GRAP):
- Restricted Entry of Trucks: Only trucks carrying essential goods or using LNG, CNG, BS-VI diesel, or electric power are permitted entry.
- Ban on Construction: Construction work at public projects has been halted to reduce dust emissions.
- Work-from-Home Initiatives: Government offices have adopted work-from-home policies for 50% of their workforce and implemented staggered timings to reduce traffic congestion.
The worsening pollution in Delhi is a collective responsibility. As individuals, we can contribute by:
- Reducing vehicle use and carpooling.
- Avoiding open burning of waste.
- Supporting greener initiatives such as planting trees and using cleaner fuels.
