Delhi is once again grappling with hazardous air pollution levels, prompting experts to declare a public health emergency. The Air Quality Index (AQI) has soared into the ‘severe’ category, with recent readings exceeding 400, far above the World Health Organization’s recommended safe limits.
Health Implications
The resurgence of toxic smog poses significant health risks to Delhi’s residents. High concentrations of PM2.5 and PM10 particles can penetrate deep into the lungs, leading to respiratory and cardiovascular issues. Medical professionals report an uptick in patients experiencing breathlessness, chest constriction, and aggravated asthma symptoms.
Government Measures
In response to the deteriorating air quality, authorities have reinstated Stage IV of the Graded Response Action Plan (GRAP), which includes:
- Educational Institutions: Schools have shifted to hybrid modes of teaching, combining online and offline classes to reduce exposure.
- Construction Activities: A complete ban on construction and demolition activities has been imposed to curb dust pollution.
- Vehicle Restrictions: The entry of non-essential heavy vehicles into the city has been prohibited to decrease vehicular emissions.
Expert Recommendations
Environmental experts emphasize the need for long-term solutions to address the recurring pollution crisis:
- Transition to Clean Energy: Phasing out fossil fuels and adopting renewable energy sources are crucial steps toward sustainable air quality improvement.
- Enhanced Public Transport: Investing in efficient and accessible public transportation can reduce the number of private vehicles on the road, thereby lowering emissions.
- Regional Collaboration: Coordinated efforts with neighboring states are essential to manage and reduce pollution sources such as crop stubble burning.
Public Advisory
Residents are advised to take precautionary measures during this period of severe air pollution:
- Limit Outdoor Activities: Stay indoors as much as possible, especially during early morning and late evening hours when pollution levels peak.
- Use Protective Gear: Wearing N95 masks can help filter out harmful particles when outdoor exposure is unavoidable.
- Air Purification: Utilize air purifiers at home to maintain indoor air quality.
The recurring nature of Delhi’s air quality crisis underscores the urgency for comprehensive and sustained interventions to protect public health and the environment.
