✦ Synopsis

Content of fluorine in vegetables and fruits from allotments situated in an industrial area as well as in an agricultural area without industrial emissions was determined. The fluorine determination was made by means of a potentiometric method with application of an ion-selective electrode. Statistically significant differences between the fluorine content in vegetables and fruits from an area contaminated with the emissions of fluorine compounds and the fluorine content in vegetables and fruits from the control area were found. Significant differences between the fluorine content in above-and under-ground parts of some vegetables were stated. The greatest fluorine content appeared in parsley haulm and in black currants.

Zusammenfassung

Fluorgehall von Obst und Gemuse aus einem lndustriegebiet

Es wurde der Fluorgehalt von Obst und Gemuse aus in einem Industriegebiet gelegenen Kleingiirten und aus in einem Gebiet ohne industrielle Emissionen gelegenen Kleingiirten bestimmt. Die Bestimmung erfolgte potentiometrisch unter Anwendung einer ionenselektiven Elektrode. Die Fluorgehalte von Gemuse und Obst aus dem belasteten Gebiet und der Kontrollproben aus dem unbelasteten Gebiet wiesen signifikante Unterschiede auf. Bei einigen Gemusearten wurden auch signifikante Unterschiede zwischen den Fluorgehalten der ober-und unterirdischen Pflanzenteile festgestellt. Die hochsten Fluorgehalte zeigten sich bei Petersilienstengeln und bei schwarzen Johannisbeeren.
