Abstract
In Surrey, car ownership and traffic flows are amongst the highest in the country.
The local borough councils have been monitoring NO] levels since 1993. This
paper presents and discusses this information with the aid of a Geographic
Information System (GIS). Data from ten fixed monitoring sites are analysed
and three of these sites, all within a busy urban town, are discussed in detail.
The results indicate no significant annual change in NO] levels from 1993-1999.
However, one site does show more variability on a monthly basis. The data from
all ten sites are combined with traffic flow information and represented spatially
using the GIS. The results highlight potential NO] pollution 'hot spots' where
the mean annual concentration exceeds 21 ppb. The work forms part of a wider
research effort aimed
