Belamie, R.
L'intérêt croissant porté aux pollutions diffuses - notamment d'origine agricole - par les gestionnaires de la ressource en eau a rendu nécessaire la mise en oeuvre de méthodologies adaptées, pour prendre en compte les multiples facteurs qui interviennent "dans les transferts des polluants (agronomique, climatiques, hydrologiques etc ) et dégager les politiques à mettre en oeuvre pour en corriger les effets.

Craker, L. E. | Fillatti, J. J.
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.
