The percentage of population exposed to a fine particulate matter (PM2.5) concentration greater than 35 micrograms (μg) per cubic meter (m3).
The World Health Organization (WHO) provides air quality guidelines based on scientific evidence and expert advice. 35 μg/m3 is interim target-1: These levels are associated with about a 15% higher long-term mortality risk relative to the Air Quality Guideline (AQG) level, which is 10 μg/m3.
Type of variable: Continuous
