Dhaka came 22nd on a global list measuring dirty air Sunday morning. The city scored 72 points on the air quality index at 10:15am. Officials labeled the air moderate, which means some people might feel sick if they exercise outside for long periods. The rating has stayed about the same for several days.

Kampala from Uganda topped the worst air list with 186 points. Lahore from Pakistan came second with 166 points. Jakarta from Indonesia finished third with 153 points. All three cities had much dirtier air than Dhaka.

The air quality index helps people understand how clean or dirty their city air is each day. Scores between 50 and 100 mean moderate air that might bother sensitive people. Numbers from 101 to 150 are unhealthy for people with breathing problems. Scores above 300 become dangerous for everyone.

Bangladesh measures five different types of pollution to create these daily scores. The country checks tiny particles, nitrogen dioxide, carbon monoxide, sulfur dioxide, and ozone levels. These chemicals can hurt people when they breathe them.

Dhaka fights air pollution problems throughout the year. Winter months bring the worst air quality to the city. Monsoon rains help wash away some pollution and make breathing easier. The World Health Organization reports that bad air kills seven million people around the world each year from lung disease, heart problems, and strokes.
