The EU has defined an Information threshold of 180 µg ozone per m3 air. Any exceedance of this threshold should be reported by the Member State in which it occurs to the European Commission. The threshold reflects a 'level beyond which there is a risk to human health from brief exposure for particularly sensitive sections of the population'. When the threshold is exceeded, national authorities are required to inform the public. See also Alert threshold.
