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

The anthropogenic interference plays more and more increasing role in modern ecologic paradigm. Adjusting this role to the studied region, it is defined by the socio-economic conditions being formed in our country. The rate of construction in the resort zones of the Krasnodar region is sweepingly rising. In spite of the high therapeutic-recreational capacity of the region, this tendency is leading to the further worsening of the ecological situation. The strengthening of the ecological control in the terms of the present economic crisis is highly urgent when more and more Russians prefer native resorts for their rest and in the first turn - resorts of the Krasnodar region. The condition of the ambient air of some recreation zones of the Krasnodar region has been studied. Methods of atomic-absorbing chromatography and optical emissive spectrometry have been used. It has been shown that the differences in data are mainly determined by the different content of the air impurities depending on the probe selection place. According to the studied data, the ecologically purest places are Krasnaya Polyana and Goryachy Klyuch. Whereas, the content of atmospheric air pollutants in the central districts of the resort towns of Sochi and Goryachy Klyuch exceeds MAC. The comparison of the obtained data with the same data of the city of Krasnodar that had been obtained before allows making a conclusion about the favorable eco-hygienic state of the resort zones of the Krasnodar region. So our investigations authentically prove the existence of the significant differences in the ecological conditions of the city on the one hand and of the resort zones of the Krasnodar region on the other hand
