The need for constant monitoring of the environmental situation due to the fact that at the present time almost all the ecosystems of our planet suffer in one way or another degradation under the influence of the anthropogenic factor. In the present work we summarize the results of 6 years of monitoring to determine heavy metals in the air. Industries and domestic waste and, in particular, road transport is the main source of pollution. The share of vehicles to air pollution in cities reaches 70-90%. The greatest danger to public health is compounds of lead, cadmium and mercury relate to 1 class of danger. We have studied the dynamics of accumulation of heavy metals and carbon monoxide in the atmosphere of Krasnodar on the streets with different intensity of car traffic. The data obtained indicate a significant excess compared to the control of the content of such metals as lead, iron, cadmium, and copper in all samples; chromium and zinc at three positions of the four. We pay due attention to the increase in the concentration of cadmium compared with data from previous years. It is established that the dynamics of accumulation of heavy metals in the atmosphere of the city is well correlated with population, the intensity of traffic and has a steady tendency to increase the content of these toxic substances. We have proposed a way of disposal of the biomass of fallen leaves by the method of their biological degradation under anaerobic conditions
