Abstract
Traffic-related air pollution is becoming a major concern in the UK, especially
in the densely populated South-East of England. Much of the focus on
monitoring of pollution levels has been on the atmospheric concentrations of
NO%. NOx includes the secondary pollutant NO?, which is produced from the
oxidation of the primary pollutant NO by ozone and partially burned
hydrocarbons. NC>2 is an important pollutant as it can trigger respiratory
problems. The Borough Councils within the County of Surrey have been
monitoring NC>2 concentrations since 1993. The sampling sites are divided into
three categories, which are defined by their proximity to a main road. These are
categorised as kerbside, intermediate and background sites. This paper analyses
the data collected from this survey, and discusses possible solutions fo
