Nitrogen Oxides under the Urban Forest Crown Cover: Migration, Transformation, Real and Possible Environmental Consequences

Has been presented the authors’ development demonstrating the possibility for determining the atmospheric air pollution in urban forest’s various areas by «passive» dosimetry’s methods. On the example of nitrogen oxides have been analyzed causes and consequences for technogenic pollution of forest ecosystems in urbanized areas. The study conducted on the territory of the Kuntsevskaya dacha’s spruce forest which is the part of the natural reserve «The Setun River’s Valley» (Moscow) has shown that in certain areas within a forest range, nitrogen dioxide accumulation in the air-ground interface can occur. Have been revealed the signs of increased nitrogen status for the investigated forest ecosystem.
