Dhaka’s air quality has seen a marginal improvement compared to Monday, yet the city remains among the world’s most polluted. Tuesday, Bangladesh’s capital ranks third worst globally, according to the Air Quality Index (AQI).
At 9:16 AM, the AQI readings showed Kolkata at 284, Lahore at 281, Dhaka at 245, Delhi at 222, Karachi at 199, Kathmandu at 184, Kampala, Uganda at 171, and Yangon, Myanmar at 171. In contrast, cities with the best air quality included Copenhagen, Denmark with an AQI of 12, Rotterdam, Netherlands with 14, Oslo, Norway with 18, and Montreal, Canada with 21.
An AQI score between 100 and 200 is classified as ‘unhealthy’, particularly for sensitive groups. Scores between 201 and 300 fall under the ‘very unhealthy’ category, triggering health warnings. In such conditions, vulnerable populations such as children, the elderly, and individuals with pre-existing health conditions are advised to minimize outdoor activities. When the AQI exceeds 300, the air quality is deemed ‘hazardous’, posing severe health risks to all residents. The AQI index serves as a critical measure, providing daily updates on air quality and associated health risks in cities worldwide.
Dhaka has long tussled with severe air pollution. Its air quality typically worsens during the winter months due to increased emissions and stagnant weather conditions. However, some relief is observed during the monsoon season.
In light of the deteriorating air quality, the Department of Environment (DoE) has urged city residents to wear face masks while outdoors. The DoE warns that Dhaka’s air quality has reached a ‘very unhealthy’ level, necessitating precautions to safeguard public health.
