WHO Air quality guidelines (AQG) in Europe
WHO Air Quality Guidelines for Europe aim to protect public health.
general, the guidelines address single pollutants, whereas in real-life,
exposure to mixtures of chemicals occur, with additive, synergistic or
antagonistic effects. The guidelines are only tentative, although emissions
should be reduced to the lowest achievable level.
|The WHO published a global update of these guidelines in 2005:
120 micrograms/ cubic meter
200 micrograms/ cubic meter
40 to 50 micrograms/ cubic meter
(0.021 to 0.026 ppm)
No guideline values were set for particulate matter because
there is no evident threshold for effects on morbidity
