POLYNUCLEAR AROMATIC HYDROCARBONS ON LEAVES
An effort was made to determine the relationship of diesel locomotive exhaust to the concentrations of polynuclear aromatic hydrocarbons on vegetation adjacent to a railroad right-of-way. The leaves of little bluestem and post oak were analyzed by means of thin-layer and gas-liquid chomatography. Anthracene, flucranthene, pyrene, benz(a)anthracene, and benzo(a)pyrene were identified and quantified. A sixth compound, 3-methylpyrene, was not detected. Higher polynuclear aromatic hydrocarbon concentrations occurred in leaf extracts of plants collected from the control area than from the railroad right-of-way. A comparison of pyrene to benzo(a)pyrene ratios suggested that most of the PAH found on the leaves were products of plant biochemical synthesis and not products of locomotive exhaust. Definite patterns of individual PAH quantities with respect to season were noted.
