The existing UK Hydrocarbon measurement
network is coming to the end of is current operational phase.
The second EU air quality daughter directive, which sets
limit values for benzene and carbon monoxide, requires the UK to
increase significantly the number of monitoring points for measuring
benzene. At the time that the additional monitoring points are
installed, most of the existing monitoring points for benzene and
1,3-butadiene are to be replaced. The new monitors, which will need
to comply with the reference method specified in the Directive for
measuring benzene against the annual limit value, will not be able to
provide information automatically updated on an hourly basis.
Until the new monitors are installed the number of hydrocarbon
measurement sites will be reduced from 13 to 4, and this site will be decommisioned
