FIELD: chemistry.
SUBSTANCE: invention can be applied for bioindication and biotesting of polluted waters and separate pollutants and can be applied as an additional method to biotests of obligatory application in determination of water quality, in which (representative) dominant species is sponge (Spongia). A method includes placement of a sponge cell suspension into a tested solution, standing for a day with the following calculation of bubble-shaped cells under a microscope, a conclusion about toxicity is made by reliable increase of the bubble-shaped cells in the tested solution in comparison with the control one.
EFFECT: considerable increase of sensitivity of the method with the minimal terms of the experiment performance.
