Worst Air Quality Country 2024? Which Nation?

Okay, so like, the worst air quality country... geez.

Basically, for 2022 (data's kinda lagged, right?), Bangladesh was apparently rocking a PM2.5 level of 54.17 μg/m3. WHO says we should aim for, like, 5. Big difference, huge. India was next with 41.39, Nepal with 39.18, and then Qatar at 39.16.

I remember reading a news article sometime maybe september or october, cant recall exact date, about air quality alerts popping up in Kathmandu after diwali holidays. I mean, you could taste the smog. Horrible.

I saw data from UChicago's ACLI (Air Quality Life Index), it felt pretty accurate with the things ive seen.
