[Accumulation of fluorine by filiform algae (Chlorophyta) agglomerations in an aqueous ecosystem with increased fluoride content].
OBJECTIVE
Studies were carried out in 1995-2005 in the Warta oxbow lake at Luboń on the accumulation of fluorine by abiotic and biotic elements of this water ecosystem.


METHODS
The reservoir had been polluted for several decades with fluorine compounds as by-products from a plant producing phosphate fertilizers. We present the results on the accumulation of fluorine by filiform algae (Chlorophyta) agglomerations. Fluorine content ranged on the average from 433 to 608 mgF/kg dry mass.


RESULTS
Studies carried out so far demonstrate that the greatest amount of fluorine accumulated in phytoplankton.
