Biochemical Markers of Contact with the Organic Pollutants of Urban Atmosphere in the Leaves of Woody Plants
Changes caused by contact with typical organic pollutants of urban atmosphere (formaldehyde, benzaldehyde, hydroperoxides) in the chemical composition of the leaves and shoots of woody plants are investigated. A decrease in quinic acid content and an increase in shikimic acid content were detected i...
