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.
- AQG level (µg/m3):
- Annual exposure: 15
- 24-hour exposure: 45
- Interim Targets (µg/m3):
- Annual exposure: 70, 50, 30, 20
- 24-hour exposure: 150, 100, 75, 50
- Health outcomes : all-cause mortality, cardiovascular mortality,
respiratory mortality, lung cancer mortality
- Causality : all associations between PM10 and
health outcomes were determined to be causal or likely causal
