Sulphur Dioxide
Pollution in the Northwest Region (covering Karlovy Vary Region,
Ústí nad Labem Region and Liberec Region) caused by sulphur dioxide in 2000 is
illustrated in maps of the fields of annual arithmetic means and 95th
percentiles of SO2 daily concentrations with presentation of measured
values at stations (Figs. 2-20, 2-21).
In the past the Northwest Region, particularly the Most Basin,
was affected by sulphur dioxide most of all. In recent years a downward
trend has been observed also in this region. This was true also in 2000
when further significant SO2 pollution decrease was recorded,
expressed especially by the levels of 24-h means. This is confirmed also by
the fact that the current limit value (IHd) was not exceeded at
any station in 2000. Only occasionally annual arithmetic mean values above 25 μg.m-3
were reported.
Suspended Particulate Matter
The SPM air pollution level in the Northwest Region in 2000
is presented in charts of annual arithmetic means, 95th percentiles of SPM daily
concentrations and 90th percentiles of PM10 fraction daily
concentrations (Figs. 2-22, 2-23,
2-24).
In the past the Northwest Region – above all the Most Basin
– was, in terms of square area, the second most affected region after Ostrava
Region in respect to SPM pollution. In recent years this type of pollution
decreased in north Bohemia. In 2000 the SPM concentrations (annual arithmetic
mean) did not reach the limit values and the daily limit value was not exceeded
in more than 5 % cases. SPM concentrations above 40 μg.m-3 in annual
arithmetic mean were measured at several urban stations in the following
Districts: Litoměřice, Ústí n.L., Chomutov and Most. In 2000 the SPM air
pollution levels throughout the Northwest Region recorded further slight
decrease. Air pollution caused by PM10 slightly decreased in rural
areas.
Nitrogen Oxides
Maps of annual arithmetic means and 95th percentiles of nitrogen
oxide daily concentrations depict the individual measuring sites in 2000 using
the method of spot symbols (Figs. 2-25, 2-26).
The highest pollution was recorded again at Public Health
Service station in Děčín-OHS at which the exceedence of the current limit
values was quite prominent. In spite of this a certain decline in absolute
values of NOx concentrations was recorded at this station. This
stations site is exposed to direct traffic influence. The daily air pollution
limit was exceeded in more than 5 % cases at several stations in the
following Districts: Děčín, Teplice, Ústí nad Labem, Litoměřice and Cheb.
Measuring sites in northwestern towns are frequently situated near roads, where
the impact of transport is evident (this is true especially in case of Děčín-OHS
station). Overall nitrogen oxide pollution in 1999 and 2000 was roughly similar,
a slight decrease was recorded in absolute values of the concentrations
measured.
The share of sulphur dioxide, which in the recent years
dominated in this regions air pollution, was comparable with the other
monitored substances. In 2000 the influence of nitrogen oxides
concentrations is dominant at several urban traffic stations. This is borne out
by Figs. 2-27 and 2-28,
which depict annual courses of the principal pollutants daily concentrations
at selected stations in the Northwest Region.
