NAS of artificial and natural origin, with depths of 2.0-4.0 m were studied. It was shown that in their hydrological characteristics NAS are close to natural reservoirs of the lake-pond complex - eutrophic lakes. It has been established that during the operation bottom sediments accumulate in them, the greatest thickness of which is noted in the initial part of the NAS. The formation of bottom sediments occurs under anaerobic conditions with the active participation of bacterial microflora in the processes of mineralization. In terms of moisture, ash content and organic matter content, NAS bottom sediments are similar to sapropels of eutrophic lakes.","PeriodicalId":385455,"journal":{"name":"SAKHAROV READINGS 2021: ENVIRONMENTAL PROBLEMS OF THE XXI CENTURY Part 2","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122717523","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To solve this problem, at the first stage of the study, a study was made of existing scientific approaches to assessing the state of the environment and the choice of a scientific basis for subsequent studies. Improving the existing scientific base in order to minimize the shortcomings of the available approaches can reduce the risk for society from the increase in anthropogenic pressure on the environment and bring closer the achievement of the global goal in the field of sustainable development of urban areas.","PeriodicalId":385455,"journal":{"name":"SAKHAROV READINGS 2021: ENVIRONMENTAL PROBLEMS OF THE XXI CENTURY Part 2","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130028607","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, 8-bromoadenosine was produced by a simple eco-friendly procedure following the treatment of nucleoside precursor adenosine with aqueous bromine solution. In the course of enzymatic transphosphatidylation reaction, the first synthesis of phospholipid derivative of the above-mentioned nucleoside -5‘-(1,2-dimyristoyl phosphatidyl)-8-bromoadenosine was accomplished.
