Query: The study of ground-level ozone in Kiev and its impact on public health   Ground-level ozone in Kiev for an episode of its high concentration in August
2000 was simulated with the model of the urban air pollution UAM-V (Urban
Airshed Model). The study of total ozone over Kiev and its concentration
changes with height in the troposphere is made on the basis of ground-based
observations with the infrared Fourier spectrometer at the Main Astronomical
Observatory of National Academy of Sciences of Ukraine as a part of the
ESA-NIVR-KNMI no 2907. In 2008 the satellite Aura-OMI data OMO3PR on the
atmosphere ozone profiles became available. Beginning in 2005, these data
include the ozone concentration in the lower layer of the atmosphere and can be
used for the evaluation of the ground-level ozone concentrations in all cities
of Ukraine. Some statistical investigation of ozone air pollution in Kiev and
medical statistics data on respiratory system was carried out with the
application of the "Statistica" package. The regression analysis, prognostic
regression simulation, and retrospective prognosis of the epidemiological
situation with respect to respiratory system pathologies in Kiev during
2000-2007 were performed.
