Delhi’s air quality has worsened further JOKE 4 was put into effect. GRAP or Phase IV Restricted Graduated Response Action Plan has been ordered to be implemented across Delhi NCR. According to the Central Pollution Control Board (CPCB), Delhi’s Air Quality Index (AQI) stood at 484 at 8 am, the worst this season.
What GRAP 4 rules may restrict in Delhi?
With GRAP 4, the following restrictions will be imposed in Delhi NCR:
- Trucks will not be allowed in Delhi except those carrying essential items or using clean fuel (CNG/CNG/Diesel/Electrical BS-VI)
- Non-essential light commercial vehicles registered outside Delhi will also be banned, except for electric and CNG vehicles and BS-VI diesel vehicles.
- Delhi-registered BS-IV or older diesel medium and heavy goods vehicles are prohibited, except for vehicles operated by essential services.
- All construction activities, including highways, roads, flyovers, power lines, pipelines and other public facilities, were suspended.
- Offices in the National Capital Region (NCR) will operate at 50 per cent capacity, while the rest will work from home
- All schools must stop physical education classes for all students except grades 10 and 12
How will an AQI of 400 and above affect the health of those living in Delhi?
An air quality index (AQI) of 400 and above is classified as “severe” and poses a serious health hazard to the entire population. At this level, the air is rich in harmful pollutants such as particulate matter (PM2.5 and PM10), nitrogen dioxide, sulfur dioxide and ozone. These pollutants penetrate deep into the lungs and blood, leading to acute and chronic health problems.
Stop Ignoring the AQI Index: Prolonged Exposure to Air Pollution May Increase Heart Attack Risk
Exposure to high levels of air pollution causes eye, nose and throat irritation, shortness of breath and coughing. Individuals with conditions such as asthma, bronchitis, or chronic obstructive pulmonary disease (COPD) experience worsening symptoms, increasing the need for hospitalization.
Greater exposure increases the risk of heart attacks, strokes and respiratory infections. It also depresses lung function, leading to fatigue and reduced ability to perform minimal physical activity.
Children, the elderly, and pregnant women are at increased risk. Babies’ developing lungs can suffer long-term damage, while pregnant women face the risk of low birth weight and premature birth.
New research links heavy air pollution to anxiety, depression and cognitive decline.
Limiting outdoor activity and using air purifiers are important precautions to minimize health effects at these dangerous AQI levels.
