In order to simplify the air purification method and increase its efficiency in our studies conducted on the Vladikavkaz - Rostov highway, the sections between the forest plantations are covered with a layer of zeolite-containing clay - allanite, and crushed corn stumps in 4: 1ratio. In this case, the stumps are pre-soaked in Zamankul mineral water, and toxic substances accumulating on the layer surface are planted: chicory, phacelia, winter camelina and annual clover species. Covering sections of the park zone with natural sources of local origin in the form of allanite clay with plant waste mixture - corn stumps, which have high sorption ability and saturated boron-containing elements of Zamankul mineral water, reduces the highway air toxicity to the maximum permissible concentrations. The analysis on the toxic substances content in the air showed that the method used and its application provide favorable conditions for a normal environmental situation on the highway. It was revealed that due to the placement of plants accumulating toxic substances along the roads in the Vladikavkaz city, their number decreased to safe, maximum permissible concentrations. Thus, the concentration of contamination with lead salts and metals from the control infected option 0.105 μg / m3 decreased to 0.018 μg / m3. The amount of zinc, nickel, manganese also decreased several times. A significant reduction in toxic elements was observed for sulfur dioxide, nitrogen oxides, volatile organic compounds, carbon, ammonia, and methane.
