Air Pollution in Karachi: Health Concerns Raised by Expert
Karachi, Pakistan is facing a serious air pollution problem, as highlighted by a recent study presented at a press conference at Aga Khan University (AKU). The study, titled ‘Impact of fine particulate pollution exposures on respiratory health in a mega city of Pakistan’, reveals that the air quality in Karachi is deteriorating due to high levels of particulate matter (PM2.5), black carbon, sulphate, ammonium, and nitrate.
Health Impacts
Prof Zafar Fatimi, the Section Head of Environmental, Occupational Health and Climate Change at AKU, shared alarming statistics. He noted a 25 to 30 percent increase in hospital admissions and emergency room visits, particularly affecting children under one year, adults over 65, and individuals with weakened immune systems. However, he emphasized that poor air quality affects everyone, even those with strong immunity.
Causes of Pollution
The study identifies road traffic and industrial emissions as major contributors to the pollution. Mismanagement of these sources is leading to poor air quality, which could reduce life expectancy in the city.
Risks of PM2.5
PM2.5 is a dangerous mix of chemicals that can cause serious health issues, including premature death, heart disease, lung infections, asthma attacks, and chronic bronchitis. Breathing in these particles poses a significant risk to human health.
Doubts Revealed
Karachi -: Karachi is a large city in Pakistan, similar to how Mumbai is a big city in India. It is known for its busy streets and many people.
Aga Khan University -: Aga Khan University is a well-known university in Pakistan, like how IITs are famous in India. It conducts research and provides education in various fields.
PM2.5 -: PM2.5 refers to tiny particles in the air that are smaller than 2.5 micrometers. They are so small that they can enter our lungs and cause health problems.
Black carbon -: Black carbon is a type of pollution that comes from burning things like coal and diesel. It looks like black smoke and can make the air dirty and unhealthy to breathe.
Prof Zafar Fatimi -: Prof Zafar Fatimi is a person who studies health and pollution. He is like a teacher who tells us how pollution affects our health.
Life expectancy -: Life expectancy is the average number of years a person is expected to live. Pollution can make people sick and reduce how long they live.
Mismanagement -: Mismanagement means not taking care of things properly. In this context, it means not handling pollution control well, leading to dirty air.
