Dhaka Tops Global Pollution Rankings: AQI Soars to 221 – What You Need to Know

Dhaka, the bustling capital of Bangladesh, has recently been highlighted for having the worst air quality, with an Air Quality Index (AQI) reading of 221, classifying it as “very unhealthy.” This is alarming news for its residents.

The AQI offers a scale to understand air quality levels. An index between 151 and 200 is considered unhealthy, while anything from 201 to 300 falls in the “very unhealthy” category. Beyond that, scores reach hazardous levels, which can pose serious health risks.

Other cities also struggle with air pollution. For instance, Hanoi in Vietnam and Delhi in India had AQI scores of 192 and 189, respectively, while Lahore in Pakistan scored 180. This highlights a regional crisis affecting many urban centers.

Air pollution in Dhaka is primarily due to five main pollutants: particulate matter (PM10 and PM2.5), nitrogen dioxide (NO2), carbon monoxide (CO), sulfur dioxide (SO2), and ozone. These pollutants can lead to severe health issues. The World Health Organization estimates that air pollution contributes to the deaths of about seven million people globally each year, with respiratory and heart conditions being major contributors.

Experts suggest that Dhaka’s air quality worsens in the winter months. This pattern may be due to increased vehicular emissions and industrial activity during colder months when winds are calm, trapping pollutants close to the ground. Conversely, the monsoon season typically brings some relief, as rain can help clear the air.

Public response to air quality data is growing. Many residents are turning to social media to share their experiences, urging the government to take stronger action on environmental policies. The hashtag #AirQuality remains trending among citizens discussing safety measures and ways to reduce pollution.

For those concerned about their health, understanding the AQI and its implications can be crucial. The index serves to inform the public about the air they breathe and possible health risks.

Improving air quality is not just about individual actions; it requires collective effort. For more information on air quality impacts and health guidelines, refer to the World Health Organization’s report on air quality.

It’s clear that Dhaka faces a significant challenge in air pollution. As residents and officials grapple with these pressing issues, ongoing awareness and action will be essential to create a healthier living environment.
