description: This work is devoted to monitoring water bodies and solving their problems. The object of the study is the water bodies of LO and St. Petersburg, microplastics, higher aquatic vegetation (HAV). The subject of the study is the methods of water purification from contamination by microplastic particles and utilization by higher aquatic vegetation. The purpose of the final qualification work is to conduct environmental monitoring of water bodies for the content of microplastics and the presence of HAV, and to propose methods for the extraction of MP and disposal of HAV. Tasks that are completed during the work: 1. Analysis of the literature review of water environmental problems. 2. Study and analysis of the problems of overgrowth of water bodies with higher aquatic vegetation (macrophytes) and pollution of natural waters with microplastics. 3. Study of existing methods for the utilization of macrophytes and purification of natural waters from microplastic pollution. 4. Environmental monitoring, water sampling and collection of higher aquatic plants. 5. Processing and analysis of water samples, investigation of the content of microplastic particles. 6. Setting up and conducting an experiment on anaerobic digestion of higher aquatic plants. 7. Setting up and conducting an experiment to remove microplastic particles in the natural waters of St. Petersburg and the Leningrad region using microalgae Chlorella kessleri. 8. Recommendations for the prevention of microplastic pollution of natural waters and utilization of higher aquatic vegetation. As a result of the work, water environmental problems were analyzed, the main existing technologies for removing microplastic particles and higher aquatic plants from water bodies were considered. Microscopy revealed microplastic particles ranging in size from 70 microns to 165 microns in various shapes and colors. A study was conducted on the removal of microplastic particles in the natural waters of St. Petersburg and Leningrad region using microalgae Chlorella kessleri. The results obtained in this work indicate the presence of a process of heteroaggregation by a strain of unicellular microalgae C. kessleri with microplastic particles. The use of microalgae to remove particles showed that with this method, the process of formation of heteroaggregation took place, and simultaneously with this process, inhibition of microalgae growth was observed. An experiment was conducted on anaerobic digestion of higher aquatic plants in order to obtain biogas. It was found that the maximum volume of methane was recorded in bioreactor No. 4 on day 44 from the beginning of the experiment, VOBM = 56% with the following ratio: biomass of higher aquatic plants (75%) and inoculant (25%). To achieve these results, the following information technologies were used in the work: Polytechnic Electronic Library (elib.spbstu.ru), scientific electronic library (www.elibrary.ru), Microsoft Word, Microsoft PowerPoint, Yandex Maps, the unified bibliographic and abstract database of peer-reviewed scientific literature Scopus, the Yandex Internet search engine.
