Dhaka, the bustling capital of Bangladesh, recently ranked 38th among the world’s most polluted cities, with an Air Quality Index (AQI) score of 61. This score falls into the ‘moderate’ category, which could pose health risks, particularly for sensitive groups.
In comparison, Jakarta, Kathmandu, and Tashkent topped the list, with AQI scores of 137 and 117. The AQI scale categorizes air quality: scores between 101 and 150 are considered unhealthy for sensitive individuals, while scores above 151 can lead to serious health issues.
The AQI measures daily air quality, indicating how clean or polluted the air is. It reflects the levels of five main pollutants—particulate matter (PM10 and PM2.5), nitrogen dioxide, carbon monoxide, sulfur dioxide, and ozone. In Bangladesh, these pollutants are a significant concern for public health.
Air pollution isn’t a new problem for Dhaka. Historically, the air quality often worsens during winter months and is somewhat relieved during the monsoon season. This cycle raises concerns, especially since the World Health Organization reports that air pollution contributes to approximately seven million deaths globally each year, primarily from heart disease, stroke, and respiratory illnesses.
Recent statistics underscore the severity of the issue. For instance, a 2021 study showed that 93% of the world’s children breathe air that exceeds safe limits set by the WHO. Engaging with this data can help raise awareness about air quality and its impact on health.
In social media discussions, many users are expressing their frustrations about air pollution, calling for more government action and public awareness campaigns. This digital dialogue highlights a growing wish for change and accountability.
With the stakes so high, addressing air pollution in Dhaka is crucial—not just for the city’s residents but for broader environmental health. For more on this topic, you can visit the World Health Organization website.
