Abstract
The aim of the study was to determine the F– content in the water of three main lakes in the Republic
of Macedonia. The estimation of F-concentration was performed using a special ion-Analyzer Model EA 920
produced by ORION, and a special ion-selective F-electrode. The results were as follows: the water from lakes Dojran,
Ohrid and Prespa contained 5.6 ppm F–, 0.08 ppmF– and 0.15 ppmF– respectively. High value on F– concentration
in Dojran Lake could be attributed to it’s tectonic genesis and supplying with water courses from mountain of
Belasica, which contains granitic rocks, characterized as very rich in fluorides mainly fluorite (CaF2), such as distribution
of zooplankton, phytoplankton, higher aquatic plants. Also the high value on F concentration may be a result
of under enormous anthropogenic influences derived from tourism and agricultural practices in the catchment area of
the lake.
