... ic flows of toxic substances. The paper contains results of a complex analysis of Kimry ecological state, including assessment of soil cover and atmospheric air pollution, magnetic component of technogenic electromagnetic fields of industrial frequency, air aero ionic composition and acoustic influences. The authors show that the maximum technogenic transformation of environmental material and geophysical components is characteristic for the Kimry central part where difficult infrastructure of the modern city is inscribed in tight space of the historic center. Pollution of soil cover and atmospheric air are due to high concentration of transport and imperfection of highways network. Universal existence of electromagnetic smog and change of air aero ionic composition are caused by low layout of city lighting and electrical power supply networks wiring. As a result the authors offer a number of ways how to improve the ecological situation. Division of business parts and cultural parts of old cities and creation of recreational and tourist clusters in the cultural part could be a cardinal solution of the historic centers problem.
