LAHORE: The provincial capital continues to grapple with severe air pollution, marking it as the most polluted city in the world with an Air Quality Index (AQI) reading of 708. This level of pollution is classified as hazardous, posing serious health risks to residents.
Smog Statistics
- Peak AQI: 708 at 11 PM
- Lowest AQI: 246 between 4 PM and 5 PM (still unhealthy)
- PM2.5 Concentration: 431 µg/m³, significantly exceeding the World Health Organization’s guidelines.
In comparison, New Delhi recorded an AQI of 232, making it the second most polluted city. Specific areas in Lahore reported even higher readings, with one location registering an alarming 953 AQI.
Causes of Smog
Experts attribute the persistent smog to various sources, including:
- Vehicular Emissions: Approximately 4.5 million motorcycles and 1.3 million cars contribute to the pollution.
- Industrial Activity: Around 6,800 factories and 1,200 brick kilns operate in and around the city.
- Stubble Burning: Agricultural burning in nearby regions like Kasur and Sheikhupura exacerbates the problem.
Environment Protection and Culture Change Department (EPCCD) Secretary Raja Jahangir Anwar emphasized that there is a lack of scientific research to determine the exact causes of smog. He noted discrepancies in various studies that attribute different percentages of pollution to vehicles and other sources.
Government Response
In response to the worsening air quality, the Punjab government has:
- A committee of 11 members has been formed to improve the credibility of AQI reporting.
- Increased the number of air quality monitors from three to a planned total of 16.
- Announced plans to conduct a scientific study with the Space & Upper Atmosphere Research Commission (Suparco) for more accurate data.
Public Health Advisory
Senior Minister Marriyum Aurangzeb has issued an emergency alert, urging citizens, especially vulnerable groups like children and the elderly, to avoid outdoor activities. Recommendations include:
- Wearing masks when outside.
- Close windows and doors to reduce exposure.
- Reporting and seizing smoke-emitting vehicles.
