The dramatic corrosive effect of motor vehicle emissions on the wax tubules in the epistomatal chambers has been followed in needles of spruce and fir with the scanning electron microscope. Fumes of aromatic hydrocarbons (benzene, xylene) were found to induce the same corrosion within days. The epistomatal waxes are considered, therefore, to be the primary target of such lipophihc compounds of polluted air and the physiological consequences of the ensuing premature stomatal obstruction to be closely related with the ‘Waldsterben’.
