The article describes the results of comprehensive research the current status of air quality in Lutsk. Lichen indication using methods and mapping the spatial distribution of derived parameters. The present study is the environmental condition of the air in the city. Lutsk and its mapping, and the subject of research were bioindication methods for determining environmental air quality, particularly lichen indication method, the feasibility of this method and prospects of assessing the degree of air pollution in towns without special expensive and complex laboratory chemical analyzes. The labor presents the authors constructed maps (lichen indication and environmental state of the air in Lutsk.) That allow qualitatively assess the zone of maximal and minimal air pollution. These cards can be widely used by scientists, students, pupils and teachers, specialists of state executive bodies, environmental and utilities to solve optimization problems of the ecological state of the environment. Based on the research and development of maps of environmental air quality in the city Lutsk authors came to the following conclusions: lichen indication method – is available, effective and cheap way to assess the ecological state of the air in cities, industrial zones and other areas. Unlike laboratory analysis of air samples, lichen indication requires no special equipment, laboratories, it is – visual and statistical studies can pursue their pupils or students. The conducted study, we assessed the general environmental condition of the air in the districts of the city Lutsk. Good and satisfactory condition, this is the only park areas of the city, in the floodplain Styr (degree of coverage tree lichens more than 30-40%), the average contamination Zones are areas adjacent to the Kivertsivska street, Big Omelyanyk, 33 quarter. Zones are heavily polluted neighborhoods adjacent to the street Lvivska, Dubnivska, Volodymyrska, Electroaparatna, Kyivski square, 40 quarter, prospect Sobornosty . This – neighborhoods with heavy vehicle traffic. Zones are areas of strong pollution Sugar factory, Str. Rivnenska, ave. Voli, 55 quarter. This industrial city areas are areas where the presence of municipal and industrial wastes combined with active traffic. Based on research developed a set of environmental maps. Growth and development lichens affect not only air pollution acidic oxides. Rather they are sensitive to humidity, temperature, presence of a bioactive agents. It would be of longer observation in terms of chemical composition and acidity of rainfall in Lutsk to establish relationships with the growth and development of lichens.
