A rapid, quantitative bioassay for detecting phytotoxic air pollutants has been developed. The technique uses wheat Triticum aestivum L. or tomato Lycopersicon esculentum L., seedlings growing on an agar medium in test-tubes. The seedlings are exposed to a pollutant in the test-tube and stress-ethylene induced by the pollutant is quantitatively measured by gas chromatography. Increases in ethylene production from seedlings exposed to a phytotoxic air pollutant as compared with controls not exposed to pollutants were related to the pollutant concentration.
