Baikal sponges account for a large, if not the largest proportion of zoobenthos of Lake Baikal, especially in the littoral. It is here that the largest number of pollutants comes. A fixed lifestyle, inertia, and the absence of visible manifestations of the life activity of the sponges create significant specific difficulties when working with them in a laboratory experiment. The lack of clear criteria, test reactions, and rapid biocontrol systems hinder the determination of the physiological state of the sponges, their activity, degree of infection, cure, and the influence of various stress factors on them. In this regard, there is relatively little information about the reactions of Baikal Porifera to toxicants. This report presents experimental materials on the change in dye absorption by Baicalospongia bacilifera sponge under the influence of one of the most common components of domestic wastewater – sodium dodecyl sulfate. A negative effect was noted with a 2-hour exposure to the sponge of this surfactant in a concentration of 25 mg/l and higher. The obtained experimental data suggest that, in further studies, bleaching of dye solutions with a sponge of B. bacilifera can serve as a test reaction for the presence of contaminants.
