Chemical-Bacteriological Composition and Assessment of Ecological Condition of Two Natural Lagoon-Type Lakes in Batumi (Adjara AR)

Abstract

Seasonal research of two relict lagoon-type lakes of Batumi (Adjara Autonomous Republic, Georgia) – Nuri-Gel and Ardagan waters has been carried out to assess their modern ecological condition. To assess the eco-situation of the lake waters, some physical, organoleptic, biochemical, chemical microbiological qualitative parameters have been experimentally determined. The topicality of the research is due to the fact that people often have an irreversible negative impact on the current sanitary-bacteriological condition of the waters of Lake Nuri-Gel and Ardagan. Based on the research, it has been revealed that in many cases the environmental quality mitigation parameters of the above-mentioned lakes are not within the maximum permissible concentration (MPC), which is caused by the negative impact of anthropogenic factors (such as draining faecal water fecal waters and various waste in lakes, caused, in many cases, by negative human activities). Due to the strategic importance of the research lakes, it is necessary to systematically research the ecological condition of their waters in order to assess the degree of cleanliness of these important ecosystems and to take timely preventive measures. At the same time, it should be noted that both lakes have recreational value and they are used for fishing, water sports and active relaxation, which further exacerbates the problem. To solve the ecological problems of Nuri-Geli and Ardagan lakes, we consider it necessary to carry out systematic cleaning works on them and to carry out periodic sanitary-bacteriological and hydrochemical control over their waters. It is necessary to work in a complex way to successfully overcome the tasks of rational use of their resources.
