The goal of the work was to determine the index of a public health threat in region of the city Dne-prodzerzhinsk air pollution from industrial plants. The analysis of the forms of 2-TP "Air" in 2010 by 8 industrial enterprises was implemented. There are 56 active stationary sources of air pollution ware identified, with priority pollutants: nitrogen dioxide, sulfur dioxide, formaldehyde, iron oxide, carbon disulfide, ammonia, phenol, carbon black, and benzo(a)pyrene. To determine the surface concentra-tions averaged simulated scattering processes and transport of pollutants from major stationary sources, taking into account the meteorological conditions. On the basis of averaged concentrations at the WHO methodology were established codes of danger to public health from air pollution. Using geoinformation technology mapping was carried out in the city and its districts ranging from the cal-culated indices of danger to public health. The level of air pollution Dneprodzerzhinsk is the greatest danger to the health of the population living in Zavodsky region. Most of the city's population lives in an area where the indices of danger to public health from air pollution by industrial enterprises rang-ing from 1 to 10, for 15% of the population, this figure more than 10, and about 8% of the population live in areas with air pollution index less
than 3.
