Dhaka recently made headlines for being one of the most polluted cities in the world. On a Wednesday morning, the Air Quality Index (AQI) hit a staggering 296, categorizing the air as ‘very unhealthy.’ This puts the health of residents at serious risk.
Other cities like Lahore, Delhi, and Kolkata aren’t far behind, with AQI scores of 324, 293, and 232. The AQI scale helps us understand air quality: scores between 50 and 100 are ‘moderate,’ while anything above 300 is deemed ‘hazardous.’
Each day, the AQI measures air pollution based on five main pollutants: particulate matter (like PM10 and PM2.5), nitrogen dioxide, carbon monoxide, sulfur dioxide, and ozone. These factors are crucial in indicating how clean or polluted the air is.
Air quality in Dhaka has been a long-standing issue. Winter months often see a dip in air quality, while monsoon seasons generally improve it. This cycle can significantly affect the health of residents. According to the World Health Organisation, around seven million people die worldwide each year due to pollution, predominantly from serious health issues like heart disease and respiratory infections.
Recent surveys show that many residents are increasingly concerned about air pollution, with social media buzzing with discussions. Awareness is growing, with many calling for better environmental policies and regulations. Experts suggest that community involvement can play a significant role in tackling this crisis.

As Dhaka tackles these air quality challenges, it’s essential for residents to stay informed and take precautions, especially during times of high pollution. Understanding air quality helps everyone make better health choices.
