Аннотация: Our earlier studies showed that paired photostimulation allows the detection of pollutantsin an aqueous medium according to the behavioral responses of freshwater Crustacea. The first stimulusinitiated and stabilized the behavioral response. The increase in response to the second stimulusmade it possible to assess the responsiveness of the zooplankton community. This paper studiesthe validity of this method for the detection of micro- and nanoplastic contamination of saltwaterreservoirs according to the behavioral response of Artemia salina and Moina salina crustaceans. Thestudies were conducted in laboratory conditions using a submersible holographic camera developedby us, which ensures the in situ detection of the concentration and speed of crustaceans in a volumeof up to 1 dm3, as well as makes it possible to change the intensity and duration of the attractinglight. It was established that the phototropic response of crustaceans decreases in seawater at thecumulative dose of exposure to microplastics—0.15 mgdm􀀀3h and nanoplastics—0.3 mg*dm-3*h.The paired photostimulation reveals the altering effect of micro- and nanoplastics in the saltwatermedium no later than 3 h after their appearance, which indicates the promising potential of thismethod for the alarm response in monitoring the environmental well-being of water bodies.
