Project summary

Most of the air contaminants in large cities and industrial centers are hydrocarbons (gaseous C1-C5 alkanes; vapors of C6-C8 alkanes; vapors of aromatic hydrocarbons benzene and toluene; aerosols containing polycyclic aromatic hydrocarbons; etc.). Plant leaves can serve as an effective means for decontamination of air from gaseous organic contaminants and organic vapors, because leaves exchange gases and vapors with the atmosphere, and the wax layer of their cuticles forms a huge lipophilic surface. By planting areas with deciduous and coniferous plants, it is possible essentially to lower the level of air contamination. For realization of the given approach, the higher plants’ ability to absorb and to decontaminate gases and hydrocarbon vapors by their leaves will be studied, and the plant species that are capable of intensively absorbing and transforming (detoxifying) hydrocarbons will be identified; the optimum composition of green area for decontamination of an atmosphere polluted with hydrocarbons will be selected; and on the basis of the resulting data practical recommendations will be developed.
