Abstract
Three Volga river delta ducts located in the city of Astrakhan and the Astrakhan region were chosen as objects for bioindication of the ecological status. The aim of the study was to carry out comparative bioelectronic diagnotics of the ecological status of the branches with different size and type of antropogenic load. The assessment was based on the physiological state (health) of the inhabitants – bivalve mollusc Anodonta anatine. The analysis of heart rate of the molluscs was implemented by the fiber-optic bioelectronic system. It has been found that Anodonta anatine collected demonstrate different heart rate recovery time after a 1-hour functional loading within 117–166 minutes. This is the case in mussels inhabiting significantly polluted water areas with the “Bad” ecological status. This characteristic of the water areas fully coincides with the ecological status of the Volga river delta ducts, according to the State report “On the state and protection of the environment in the Russian Federation in 2017”. In this report, the authors propose and substantiate the possibility of using the water area of the Gandurino River as a conditional reference duct for the Volga river delta region. In this case, by the value of the Ecological Quality Ratio (EQR),the status of the Gorodskoy and Maly ducts may be considered as “Good” regional ecological status.
