Field testing of an innovative technology based on a bioelectronic cardiac monitoring system was carried out in the Gulf of Finland (Baltic Sea).
The study shows that the bioelectronic system is suitable for the selected bivalve mollusks Mytilus trossulus, Macoma balthica and Anodonta anatina. Specimens taken from reference sites demonstrated a heart rate recovery time of <60 min after testing with changed salinity load, while those collected from sites characterized by high anthropogenic pressure demonstrated a prolonged recovery time of up to 110-360 min. These results make possible a discrimination of the study sites based on the assessment of physiological adaptive capacities of inhabiting species. In addition, the approach of measuring heart rate characteristics in M. balthica transplanted in cages to specific target areas was successfully used to evaluate the decline in the adaptive potential of mollusks exposed at polluted sites.
Application of the novel system is a useful tool for the biomonitoring of freshwater and brackish water areas. Development of methodological basis for the testing of adaptive capacities (health) of key aquatic organisms provides new knowledge of biological effects of anthropogenic chemical stress in aquatic organisms.
