Discover Why Dhaka’s Air Quality Remains ‘Moderate’ with an AQI of 75

Dhaka, the bustling capital of Bangladesh, recently ranked 19th for poor air quality, with an AQI score of 75. This score was recorded around 10:00 AM on Tuesday. The air quality has been classified as ‘moderate’ for four days in a row, indicating a slight health concern.

The Air Quality Index (AQI) helps us understand the cleanliness of the air we breathe. For instance, an AQI between 50 and 100 is deemed ‘moderate’, where sensitive individuals might want to limit long periods outdoors. When the AQI rises above 100, the air becomes ‘unhealthy for sensitive groups’, and by the time it hits 301 or above, it’s labeled ‘hazardous’, posing serious health risks.

In a global context, Kinshasa in the Democratic Republic of the Congo leads the list with an AQI of 167, followed by Manama in Bahrain and Jakarta in Indonesia, both at 153. This data highlights a growing concern about urban air quality worldwide.

In Bangladesh, the AQI is gauged based on five key pollutants: PM10, PM2.5, NO2, CO, SO2, and ozone. Over the years, Dhaka has faced persistent air quality challenges. It tends to worsen in winter but improves during the monsoon season. This cyclical pattern affects many residents, particularly those with pre-existing health conditions.

According to the World Health Organization, air pollution is responsible for about seven million premature deaths globally each year. Conditions like stroke, heart disease, and respiratory infections are significantly linked to poor air quality. Local health expert Dr. Ayesha Rahman emphasizes, “Addressing air pollution is vital. It’s not just an environmental issue; it directly affects human health.”

Rising public concern has fostered social media discussions. Many people have taken to platforms like Twitter to share their experiences with air pollution, highlighting its impact on daily life. More awareness and community engagement are needed to tackle this pressing issue.

As we continue to monitor air quality in cities like Dhaka, it’s crucial to understand the broader implications of pollution on health and urban living. With informed decisions and collective action, we can work towards cleaner air for all.
