where SD is the normalised standard deviation of data at monitoring stations. Based

on the data in the APIS database it is estimated that there is a slight variation between

stations, but the standard deviation is generally consistent for NO2 throughout the

European Union.

For Y the criteria used is 3 times standard deviation.

For NO2 the data in the Air Pollution Information Service (APIS database have been

used to calculate X and Y, Table 2.5 The span given is the approximate range

calculated. The recommended value is given without brackets.
