In Russia, it amounts to about 75%. Green spaces play a leading role in the process of maintaining the ecological balance of urbanized territories. One of the main sources of environmental pollution in cities are cars. Monitoring the condition of woody plants in outdoor plantings is an important part of assessing the condition of urban systems. The purpose of the work is to conduct a comprehensive assessment of the ecological state of tree plantations in the street plantings of Balashikha, a city, which is a part of Moscow agglomeration. The study was carried out in 2019-2021 in 20 streets of Balashikha. The species composition, the vital state of tree and shrub vegetation in street plantings according to Alekseev’s methodology and winter hardiness according to Lapin and Sidneva’s methodology were revealed. The following results were obtained: in the street plantings of Balashikha there are 21 species of trees and shrubs, the average age of tree plantations is 30-40 years, the most common ones are Аcеr nеgundo L., Аcеr plаtаnoidеs L., Tiliа cordаtа Mill., single - Acer tataricum L., Pinus sylvestris L., Sorbus aucuparia (L.) Gaertn., Ulmus laevis Pall. In order to maintain sustainable development, it is necessary to change the strategy of urban greening (implement a more diverse species composition, conduct monitoring studies involving not only utilities, but also researchers dealing with urban ecology problems, apply modern maintenance technologies. Recommendations are given on the introduction of new types of woody plants for outdoor plantings to improve the ecological situation in Balashikha.","PeriodicalId":190056,"journal":{"name":"RUDN Journal of Ecology and Life Safety","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126764212","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}

An indicator of carcinogenic environmental impacts is childhood tumors due to the predominantly prenatal genesis of tumors at this age. In the structure of childhood oncological morbidity, hemoblastosis predominate. The link between the incidence of childhood leukemia and exposure to ultraviolet radiation, the protective role of sun exposure in relation to the risk of non-Hodgkin’s lymphomas (NHL) and the absence of such in Hodgkin’s lymphoma in children have been established. There is evidence of the connection between childhood hemoblastosis and smoke of various origins. The aim of the study was to evaluate the link between solar activity and smoke with hemoblastosis in the Russian children. We used official data on the incidence of childhood hemoblastosis in Russia in 1997-2020 and data on solar activity from the site of the Royal Observatory of Belgium. The generated dynamic series was subjected to correlation and regression analysis in 11 consecutive iterations with a time delay (lag) from 0 to 10 years in relation to the year of registration of neoplasms. An increase in the incidence of leukemia and a decrease in the incidence of Hodgkin’s lymphoma in the children’s population of Russia have been established. The incidence of NHL in children did not reveal a significant trend. A general pattern was revealed in the form of the connection between childhood leukemia and lymphomas and solar activity, most pronounced in 1997-2008. The increase in the childhood leukemia incidence, taking into account the literature data of the role of exhaust gases in its genesis, can be associated with a threefold increase in the number of cars in Russia during the study period. The reasons for the decrease in the incidence of Hodgkin’s lymphoma require further study. To reduce the risk of hemoblastosis in children, it is advisable to introduce food products into the diet to stimulate autophagy, and transfer factor.","PeriodicalId":190056,"journal":{"name":"RUDN Journal of Ecology and Life Safety","volume":"105 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124039550","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}

The simplest and clearest methods for assessing the impact of generated waste on the environment are bioindicative methods, in particular, the assessment of phytotoxicity. The analysis of the phytotoxic effect of ash and slag wastes of various origins and different periods of storage, as well as coal samples in the conditions of urban settlements, was carried town Shakhtersk, Sakhalin region, in relation to herbaceous plants of various systematic groups in the framework of a number of laboratory experiments. The phytotoxic effect of the considered samples was determined by comparing the parameters of the test function of the control and experimental seeds. The dependence of the magnitude of the phytotoxic effect on the shelf life and the type of origin of ash and slag waste is shown. The data obtained are the basis for carrying out additional experiments and studies, as well as determining the chemical composition of the samples under consideration.","PeriodicalId":190056,"journal":{"name":"RUDN Journal of Ecology and Life Safety","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125517462","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}

Increasing requirements for the environmental safety of wastewater discharge into natural water bodies determines the particular relevance of improving technological methods and wastewater treatment facilities. In the world practice of post-treatment, preliminary filtration and filtration are rightfully considered one of the most effective methods. At the same time, one of the most common devices used in post-treatment of wastewater are sand filters with granular filter material, the effectiveness of which is often overestimated. The problems of post-treatment of wastewater by filtration using sand filters with a granular filter load are considered, the main problems that arise when using such devices are considered without taking into account the features of post-treatment processes in the presence of organic matter in highly dispersed colloidal forms. Substantiated are additional requirements for reducing the concentration of toxic substances when discharging wastewater into natural water bodies and minimizing changes in the conditions for the development of the biocenosis of these objects. The reasons for the insufficient efficiency of wastewater post-treatment on sand filters, including the reasons for the increase in the content of organic substances in the filtrate after post-treatment, are determined. The main criteria for the effective use of filtering devices in wastewater treatment systems are formulated.","PeriodicalId":190056,"journal":{"name":"RUDN Journal of Ecology and Life Safety","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129273941","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}
