BackgroundThe purpose of the research was to provide the review of the institutional and legal requirements and evaluation of the existing sanitary-biological research of the Lake Paliastomi waters; study the current state of environment, problems of pollution from agricultural sources, municipal wastewater and industry in line with the bacterial pollution caused by migratory waterfowl of the Lake Paliastomi, an internationally recognized habitat, wintery and transit area of the birds and an important tourism site. ResultsHave been prepared the analytical data on: the review of the institutional and legal requirements; evaluation of the existing sanitary-biological research of the following waters in the Lake; definition of dynamics of sanitary-microbial indicators in flowing waters; study of biological characteristics of secreted pathogenic agents and definition of their vulnerability towards bacteriophages; mathematical simulation model on different scenarios of dissemination of chemical pollutants and pathogenic bacteria in the lake Paliastomi. The researchers identified that the pollution by nutrient-rich water causing large blooms of algae and aquatic plants that in its turn leaves little oxygen for fish and other aquatic animals, resulting in the eutrophication followed by suffocation of aquatic life.ConclusionsThe solution of problem requires complex respond: the selected spring sites, regular monitoring of nitrate contents and other basic physico-chemical water parameters; simultaneous, continuous discharge recording; monitoring and maintaining water levels in the wetlands; removing sediment and organic debris build up in wetland pond and etc.Mathematical modeling of dissemination of the pathogenic bacteria in the Lake Paliastomi enables us to permanently monitor not only the inflowing waters of Paliastomi Lake, but seasonal sources of bacterial pollution due to the migratory birds. In line with monitoring, localized prophylactic point sources spraying of Salmonella bacteriophage cocktail (SBC) by agricultural drones will be useful to restrain bacterial contamination.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
