ISLAMABAD: Swiss air monitor index IQAir ranked Pakistan’s eastern city of Lahore as the most polluted in the world on Wednesday, recording its Air Quality Index (AQI) at 331 as it continues to choke from toxic winter smog.
Lahore faces worsening smog each winter from crop burning, vehicle emissions and industrial pollution that threaten public health and daily life. Smog can cause sore throats, eye irritation and respiratory illnesses, while long-term exposure increases the risk of stroke, heart disease and lung cancer.
The global air monitoring index said Lahore’s AQI was recorded at 331, deeming it at the “hazardous” level while its Particulate Matter (PMI) was recorded at 2.5 around 7:00 p.m. local time on Wednesday.
“PM2.5 concentration is currently 48.1 times the World Health Organization (WHO) annual PM2.5 guideline value,” IQAir said.
India’s capital New Delhi was ranked at number two with an AQI of 290, while the China’s Beijing recorded an AQI of 228, making it the third most polluted city worldwide.
IQAir added Pakistan’s commercial hub Karachi, which ranked at number 10 on its list of world’s most polluted cities on Wednesday, recorded an AQI of 124. The air monitor recorded its AQI as “unhealthy for sensitive groups.”
“PM2.5 concentration is currently nine times the WHO annual PM2.5 guideline value,” IQAir said about Karachi.
Smog season begins in late October, peaks from November to January and lasts through February.
Earlier in October, the government in Pakistan’s most populous Punjab province conducted its first anti-smog gun operation, which helped lower the city’s unhealthy air quality levels. Anti-smog trucks sprayed fine water mist across the city to help settle dust and pollutants.
Pakistan’s main urban centers routinely rank among the most polluted cities in the world, with vehicular emissions remaining one of the top contributors to air pollution.
This severe air pollution also undermines economic productivity and diminishes the quality of life for millions of residents.
