The use of biological objects in monitoring the state of the environment and the changes caused by the impact of environmental pollution on marine and fresh waters is a promising tool due to a lower cost in comparison to traditional monitoring and the ability to receive immediate information about the ecosystem status. In this review, we summarize the biological information about shellfish biomonitors and the results of studies focused on the development and use of the bioindicator species in early warning systems in Russia. Since the mid-1980s, Russian specialists have developed online biomonitoring systems; as in the rest of world, there are two main approaches that are currently applied to study the physiological status of potential biosensor shellfish species and to monitor freshwater and marine systems: valvometry (registration of gaping activity in bivalve mollusks) and photoplethysmography (registration of cardiac activity in mollusks and crustaceans). Valve movement responses to stressors such as abnormal conditions and pollutants include the closure of shell valves for a long period, decrease in the average distance between valves, rapid shell opening, and higher closing frequency. Cardiac activity reactions of shellfish to stress factors include rapid increases in heart rate and stress index, higher variability in heart rate than under normal conditions, and longer periods required for heart rate recovery after stress. The most common bioindicators used to monitor environmental disturbances in marine ecosystems are blue mussels, Iceland scallops, and red king crabs in cold-water habitats and Black Sea mussels in warmer waters as well as freshwater mussels and crayfish in fresh waters.

Environmental and Technological Aspects of Redox Processes

As human civilization develops, environmental problems arise more and more often. All forms of the environment are consistently exposed to pollution: water, air, and soil. In the natural aquatic environment, redox processes occur, in which both endogenous and exogenous substances are involved. The processes of antagonism and synergy are also realized, which leads to a decrease or increase in the toxicity of the environment. All this affects intra-aquatic processes, which, as a result, lead to the formation of the quality of the aquatic environment. Historically, there have been three main approaches to assessing water quality using biological objects. These are biodiagnostic methods: bioindication, bio marking, and biotesting. The review reveals the features of biodiagnostic methods and their application in assessing the quality of natural waters.

The current state of the concept of the health of aquatic ecosystems and the main methods and technologies (mainly instrumental) for its assessment are briefly considered. The data obtained during the study of the health of ecosystems of several recreational areas of the Black Sea, the eastern part of the Gulf of Finland, several channels of the Volga delta are considered. An operational assessment of the health of ecosystems was carried out using innovative biomonitoring technology by testing the health of adult bivalve mollusks living in them by the functional load method based on the analysis of their heart rate, measured using the BioArgus bioelectronic fiber-optic system. It has been established that the functional state of mollusks can serve as an indicator of excess pollution of coastal waters by objects that discharge insufficiently treated domestic wastewater from their local treatment facilities, including household wastewater. It is concluded that, taking into account the rather high rapidity and ease of use, this technology can be effectively used to solve the problems of screening studies and early diagnostics of the state of aquatic ecosystems as well as serve as an information basis for developing regionally oriented, science-based environmental management decisions.
