Abstract
In the present paper the authors establish the influence of the fluor
ion resulted from a sulphuric acid and chemical fertilizer plant, on 
the marine flora and fauna. Owing to the different degree of solubility 
of the flour compounds, the laboratory experiments were carried out 
with calcium fluoride - (CaF2)- and with sodium fluoride - (NaF). The
concentration of the respective solutions ranged between 2 and 100 
mg per litre. Observations were made on the behaviour of various 
species of fish, mollusks and crustaceea, in solutions of varying 
concentration.
