Dhaka, the bustling capital of Bangladesh, recently ranked fifth among the world’s cities with the worst air quality, hitting an Air Quality Index (AQI) of 194 early one Saturday morning. This level is deemed ‘unhealthy.’
For context, cities like Lahore, Cairo, Delhi, and Kolkata topped the list. Lahore scored 309, while Cairo was at 306, Delhi at 239, and Kolkata at 199. The AQI scales from 0 to 500: an AQI between 151 and 200 signals that the air is unhealthy, impacting everyone’s health, especially those with pre-existing conditions.
The AQI reflects levels of various pollutants, including particulate matter (PM10 and PM2.5), nitrogen dioxide (NO2), carbon monoxide (CO), sulfur dioxide (SO2), and ozone. In Dhaka, air quality usually worsens in winter but tends to improve during the monsoon season.
Experts note that air pollution in urban areas is not just a local issue; it’s a growing global concern. The World Health Organization (WHO) indicates that air pollution is linked to nearly seven million premature deaths each year. This issue is particularly pressing for cities like Dhaka, where traffic congestion and unregulated industrial emissions are major contributors.
Historically, Dhaka has battled air quality problems for years, highlighted in various reports, including one from the Bangladesh Environmental Lawyers Association. Despite efforts to improve conditions, such as promoting green energy and better public transport, the problem persists. Residents report frequent health issues during heavy pollution days, and social media trends reflect widespread concern and frustration over the city’s air quality.
In a 2023 survey by the Bangladesh Bureau of Statistics, 65% of respondents expressed worry about their health due to air pollution. Many shared their experiences online, discussing how they cope with the effects, like using air purifiers or wearing masks.
For more detailed health impacts and initiatives to combat air pollution, you can refer to the WHO’s guidelines on air quality and health.
As cities globally confront air quality challenges, Dhaka remains a critical example of how urban growth can clash with environmental sustainability.
