KARACHI: Lahore has once again recorded the worst air quality in the world, maintaining its position at the top of the global pollution rankings, while Karachi has moved up to seventh place, according to the latest Air Quality Index (AQI) data.
Data shows that Lahore’s air quality remains at hazardous levels, with particulate matter (PM) concentration recorded at 404, while Karachi’s reading stood at 147, indicating unhealthy air conditions.
Under the AQI scale, pollution levels between 150 and 200 are considered unhealthy, 200 to 300 are categorized as very unhealthy, and readings above 300 denote hazardous air quality.
Meanwhile, India’s capital New Delhi ranked second, and Beijing, the capital of China, secured the third position on the global pollution index.
Experts attribute the worsening air quality to seasonal changes, industrial emissions, heavy traffic, and irresponsible waste disposal practices.
