چکیده    The types and degree of anthropogenic impacts have an effect on the ecological state of the environment. there are two main sources of pollution on the territory of cities: industry and motor transport. currently, with a significant reduction in industrial production, road transport is one of the main sources of environmental pollution. the largest amount (more than 200) of air pollutants is provided by gasoline carburetor engines: carbon monoxide, nitrogen oxide, unburned hydrocarbons. when 1 liter of gasoline is burned, 200-400 mg of lead is released, thus, one passenger car emits up to 1 kg of lead into the city atmosphere per year. diesel engines pollute the atmosphere with soot, sulfur compounds, benzo pyrene. according to american geochemists, in cities more often than in rural areas, we observe cloudy weather, more rain and less snow. atmospheric dust in cities is 100 times more, exhaust gases, 525 times more than in agricultural landscapes. all this affects the health of the population. the favorable factor is that the main streets with heavy traffic are located on the watersheds, in the upper part of the city, where conditions are better for dispersing impurities. however, on streets descending into depressions, where air stagnation and surface inversions are more likely, and where uphill vehicle emissions increase, air pollution is upraised.
