摘要

目的。分析地表水水体的质麦芽,确定其生态状况的变化。根据Psel河2012 - 2020年“乌克兰水资源监测和生态评估”互动地图,对以下指标进行了生态状况变化的统计和系统分析:硝酸盐,亚硝酸盐,磷酸盐,铵离子,硫酸盐,氯化物。结果。研究发现,2019年Psel河的总磷酸盐含量从Nr 1点到Nr 6点呈下降趋势。与此同时,比什金村附近也有显著增加。原因可能是在没有治疗设施的定居点安置了栅栏柱。硝酸盐浓度增加,而在Kaminne村和Velyka Bagachka城市型住区,硝酸盐浓度下降,这可能与他们消耗浮游植物有关,这应该导致浊度和生物需氧量增加。亚硝酸盐浓度的增加表明有机质分解的强度增大,NO2 -氧化为NO3 -的时间延迟,表明水库受到污染。硝酸盐和亚硝酸盐从工农业企业的废水中进入水中。铵离子浓度的下降(Chervone村)很可能是由于它们被氧化,被氧气溶解在水中,形成硝酸盐离子。氯的含量增加了。Byshkin村和Kaminne村附近氯化物浓度的增加是由于生活污水污染了地表水。硫酸盐的含量增加了。该企业在生产化肥或化学品的工艺过程中使用硫酸。因此,可以认为企业排放的未经处理的水可能是导致河水中硫酸盐含量增加的原因。根据2012 - 2020年“乌克兰水资源监测和环境评估”数据,对普塞尔河生态状况的变化进行了分析。结果表明,浦塞河受到规律性的技术影响,其生态状况有持续恶化的趋势。

Environmental Assessment of Surface Water Body Quality (on the Example of the Psel River)
Purpose. To analyze the qualitative malt of the surface water body to determine changes in its ecological status. Methods. Statistical and systematic analysis of ecological status changes was performed according to the interactive map "Monitoring and ecological assessment of water resources of Ukraine" of the river Psel for 2012 - 2020 on the following indicators: nitrates, nitrites, phosphates, ammonium ions, sulfates, chlorides. Results. It was found that in the Psel River in 2019 there was a decrease in the total phosphate content from point Nr 1 to point Nr 6. At the same time, there is a significant increase near Bishkin village. The reason may be the placement of a fence post in a settlement where there are no treatment facilities. There is an increase in nitrate concentration, while in the Kaminne village and Velyka Bagachka urban-type settlement there is a decrease in nitrate concentrations, which may be associated with their consumption of phytoplankton, which should lead to increased turbidity and biological oxygen demand. The increased concentration of nitrites indicates the intensity of decomposition of organic matter, and the delay of oxidation of NO2– to NO3–, which clearly indicates the pollution of the reservoir. Nitrates and nitrites enter the water from the effluents of industrial and agricultural enterprises. The decrease in the ammonium ions concentration (the Chervone village) is most likely due to their oxidation, dissolved in water by oxygen, with the formation of nitrate ions. There is an increase in chloride content. The increase in chloride concentration near the Byshkin village and the Kaminne village is due to the pollution of surface water bodies with domestic wastewater. There is an increase in the sulfates content. For the manufacture of fertilizers or chemicals in the technological process at the enterprise sulfuric acid is used. Therefore, it can be assumed that the discharges of untreated water by the enterprise can be the reason for the increase in the content of sulfates in the river water. Conclusions. An analysis of changes in the ecological status of the Psel River on the basis of data «Monitoring and environmental assessment of water resources of Ukraine» for 2012 – 2020 was performed. It is revealed that the river Psel is under rgular technogenic impact, has a tendency to steady deterioration of its ecological condition.
