Abstract

Fluorine pollution (chronic or occasional) around a plant rejecting gaseous fluoride effluents can be detected from vegetation samples by chemical analysis. Systematic monitoring allows the effects and gravity of the pollution to be estimated. The analytical method used consists of a double distillation (in phosphoric acid and perchloric acid) followed by a spectro-colorimetric analysis (alizarine-complexon-lanthane). This method of control allows both the efficiency of the trapping installations and also the appearance of effluents at unexpected places to be checked, In the event of an accident it is possible to determine the advisability of prohibiting the consumption of locally grown produce by humans or fodder by cattle. Research conducted in order to determine the relation between visible, damage to certain vegetables (tomatoes, haricot beans and sorghum) and their fluorine contents demonstrated that such a relation appears above all at the level of the leaves; chemical analysis may thus be used to confirm or reject information obtained on the basis of visual evidence [French] La detection d'une pollution fluoree (chronique ou accidentelle) autour d'une usine susceptible d'emettre des effluents gazeux fluores peut etre avantageusement realisee par un reseau de prelevements vegetaux suivis de dosages chimiques.

Une surveillance systematique permet une evaluation des consequences et du degre de gravite de la pollution. La methode d'analyse consiste en une double distillation (dans l'acide phosphorique et l'acide perchlorique) suivie d'une spectrocolorimetrie (alizarine-complexon-lanthane). Ce mode de controle permet non seulement de verifier si les installations de piegeage sont efficaces mais egalement de localiser des points d'emission imprevus. En cas d'accident, on peut egalement juger de l'opportunite d'interdire la consommation des legumes par les habitants ou du fourrage par le betail des environs. Enfin, des etudes experimentales ont ete realisees pour etudier la relation entre les lesions visibles sur les vegetaux et la teneur en fluorures de leurs tissus. Il ressort de ces essais sur differents vegetaux (tomates, haricots, sorghos) que cette relation existe surtout au niveau des feuilles; on pourra ainsi par le dosage chimique confirmer le diagnostic visuel des lesions fluorees ou au contraire l'infirmer et rechercher une autre cause.}
