- It is not possible to produce regional estimates for air quality as
there are too few monitoring sites within each region.
- Of the 49 sites in England for which there were data in 2005, the
top six sites with the highest number of days of moderate or higher
air pollution contained four sites from the East of England. Five of
these six sites were in rural locations:
Sibton (E) 97 days Weybourne (SE) 74 days London Marylebone Road [urban]
(L) 70 days Lullington Heath (SE) 69 days Wicken Fen (E) 55 days St Osyth
(E) 54 days
- In 2003 two sites (London Marylebone Road and Lullington Heath) experienced
at least 100 days of moderate or higher air pollution. No sites experienced
100 or more days of moderate or higher air pollution in 2005.
- Generally speaking, urban areas experienced less air pollution than
rural areas in 2005.
- 45 sites in England were used for measuring particulates (PM10)
in the air in 2005. The two sites with the highest levels of PM10
were in London (Marylebone Road and Camden (kerbside)
- Of the 42 sites for which comparisons are possible, levels of PM10
increased in 16 sites by 5 per cent or more. The largest increase was
in Middlesbrough in the North East. The largest decreases were seen
in Norwich (East), and Plymouth (South West) city centres.
- 63 sites in England were used for measuring ozone in 2005. The highest
levels of ozone were at the following sites:
Weybourne (East of England) Sibton (East of England) Lullington Heath (South
East) Yarner Wood (South West)
- Of the 55 sites for which comparisons are possible, levels of increased
by five per cent or more in 9 sites between 2004 and 2005, with the
largest increase being in Hackney (London) and the largest decreases
in Sheffield centre (Yorkshire and the Humber) and Manchester south
(North West).
