1.2 PM10
PM10 are defined by an aerodynamic diameter of less than or equal to 10µm.1,3 AQG and interim target levels were set based on the pollutant-attributed increase in all-cause non-accidental mortality or cause-specific mortality with high certainty of evidence. In situations where both PM2.5 and PM10 measurements are available, priority should be given to PM2.5 AQGs.
