BIOTESTING OF TOXICNESS OF WATERS ON SPEED OF ABSORPTION OF MICROALGAE DAPHNIA REGISTERED BY FLUORESCENCE OF CHLOROPHYLL
The possibility to use the fluorescence parameters for determination of the concentration changes algae in media studying the filtration feeding of Daphnia magna has been investigated. On the basis of experiments studying the influence of different toxic substances on Daphnia magna feeding behaviour a sensitive toxicological express test has been proposed.
