Air quality |
The level of atmospheric air pollution
in the city is above the average in comparison with other Commonwealth
of Independent States countries having the same population.
The double fall of the industrial production volume since 1991,
especially the processing sector, should have led to a substantial
improvement of the situation. But the expected improvement did not
ensue: the volume of the emissions of the heat-and-power engineering
complex remained practically on the same level and the
transport exhaust increased.
The
meteorological conditions and orography have a considerable impact
on the state of atmospheric air. The frequency of low speed of the
wind (0-1m/sec.) in the city during the year was 42% and 56 % in
the autumn-winter time. The location of the city on a piedmont plain
and the pronounced mountain-to-valley atmospheric circulation favour
the formation of powerful and deep ground inversions. In 60 % of
cases these inversions are observed when the winds are directed
southeast and south. On the average during the year 17% of ground
inversions are accompanied by a weak wind, and in certain months
air blanketing reached 27%.
