Dhaka ranked 13th worst among global cities for air quality on Saturday morning, recording an AQI of 121. That level is classified as unhealthy for sensitive groups, meaning children, older adults, and people with heart or lung conditions face higher health risks. Lahore, Kolkata, and Kuching topped the list with worse readings. The AQI in Bangladesh measures PM10, PM2.5, NO2, CO, SO2, and ozone. Air quality typically degrades in winter and improves during monsoon. The WHO estimates air pollution contributes to about 7 million deaths worldwide each year, mainly from stroke, heart disease, and respiratory infections.

AQI 121 in Dhaka, not terrible but not good. Sensitive groups should stay indoors. Would be curious to see the PM2.5 and PM10 split, that tells you more about the source. Anyone know if the winter spike is mostly from construction dust or vehicle emissions?

The WHO 7 million deaths stat is a big number. Air quality in South Asia is driven a lot by coal plants and diesel backup generators. If they tightened emission limits on those, you'd see real improvement. Also, indoor air quality matters, people spend most of the day indoors.

The AQI scale is useful but it's a single number. The real policy question is whether they're enforcing the pollution controls that already exist. Bangladesh has standards, but enforcement is weak. Also, they should consider tighter fuel standards and better public transit to cut vehicle emissions.

For building owners, this is a reminder to check HVAC filters and maybe add MERV-13 filtration. It's cheap compared to health costs. Also, sealing windows helps. Not a full solution but reduces exposure for those sensitive groups.
