Air Pollution in American Samoa
American Samoa faces significant air pollution challenges. 0% of states exceed the WHO guideline for clean air. This is putting 42 thousand across 4 states at risk.
The average PM2.5 over 2023 was 1.2µg/m³. That's 0.2 times the WHO guideline for clean air of 5µg/m³.
This is equivalent of everybody, including children, smoking about 20 cigarettes in a year.
