Effects of air pollution on plant life

A detailed review of the progress of research on the effects of sulfur dioxide hydrogen fluoride, and smog since 1950 is presented. Fluoride appears to be a cumulative phytotoxicant which may move through the plant vascular system to the leaf tip or margin and produce foliar necrosis upon accumulation of a threshold concentration. Evidence also points toward possible enzymatic inhibition. Sulfur dioxide and smog exposures result in foliar injury only if the rate of tissue absorption exceeds the rate at which the plant can effectively neutralize the toxic agent. Smog, however, can produce growth inhibition without producing visible injury, whereas sulfur dioxide does not produce this so-called invisible injury. Reference is made to a catalogue of common weeds according to their characteristic foliar response and susceptibility to a number of pollutants.
