The past couple days I noticed there was more haze in the sky and distant buildings were harder to see but I didn’t notice any difference in breathing. But now the paper says two days ago Phnom Penh (arrow) was the second most air-polluted city in the world, behind only Dhaka, Bangladesh. Today the visibility is much greater and the air quality number is 84, much lower than the previous 190+. Air pollution is not something Phnom Penh is noted for.
