A senior expert in his study raised serious concerns over the increase in the level of air pollution during a press conference on Friday at the Aga Khan University (AKU), affecting the respiratory health of the people in Karachi district of Pakistan, as per a report by Dawn.  

A study presented by environmental health expert Prof. Zafar Fatimi at Aga Khan University (AKU) highlights alarming levels of air pollution in Karachi, significantly affecting respiratory health. The study, titled Impact of Fine Particulate Pollution Exposures on Respiratory Health in a Mega City of Pakistan, identifies particulate matter (PM2.5) as a major contributor to respiratory issues in the city, according to a report by Dawn.

High concentrations of black carbon, sulphate, ammonium, and nitrate were found to exacerbate air quality problems. Prof. Fatimi noted a 25-30% rise in daily hospital admissions and ER visits, particularly impacting children under one year, adults over 65, and those with weakened immune systems. 

He emphasized, “Poor air quality affects everyone, even those with strong immunity, as the particles we breathe in can gradually impair bodily functions.”

The study further attributes Karachi's air quality crisis to industrial emissions and traffic pollution, compounded by ineffective management. Experts warn that prolonged exposure to PM2.5 can lead to severe health conditions like heart disease, asthma, and chronic bronchitis, ultimately reducing life expectancy in the region.
