Abstract

The method of determining toxicity in streams by the use of axenic cultures of the protozons species Tetrahymena pyriformis is described. Contrary to the similar tests which are used in medicine in defined but rather complicated culture media, for the toxicological experiments in surface water it is possible to use very simple media for the cultivation of test organisms. Duration of the whole direct test of toxicity is limited to 24 hours. The other advantages of using the test organism Tetrahymena pyriformis are mentioned as well. According to the agricultural and industrial pollution which often takes place in our surface waters five chemicals, most of them pesticides, were tested.
