The dynamics of the number of the microalga Dunaliella salina, depending on the age of the matrix culture, the number of cells, and the time of toxicant administration in the culture medium and on oxygen production as a parameter of the functional condition of the dunaliella, was studied in solutions of sodium dodecylsulfate (SDS) containing 0.1, 1, and 10 mg/l of the detergent. The parameters at which the application of the considered test-object allowed determination of the most exact information on the environment quality and toxicity of substances were determined. It was shown that the SDS in concentrations of 0.1 and 1 mg/l did not affect significantly the growth of the microalga, and an inhibiting effect was recorded at a toxicant content of 10 mg/l.
