There is studied the ecological status of surface waters in Busk district. The attention is focused on the largest river Western Bug and its tributaries which essentially influence on the ecological condition. The analysis of hydrological monitoring in the basin of the Western Bug is done. Analysis of water pollution in the river is performed with use of fixed position state hydrological monitoring system posts. There are studied the data concerning pollution indicators for 2015 year and 3 seasons of 2016. A comparison of contamination in two points outside the district is carried out. There are considered river Poltva before its waters reach the district and flow into Western Bug and the river Western Bug after it lefts the district. The exceeding of the threshold limit values for some indicators is revealed. In all cases there is a slight excess of the TLV over the content of iron and ammonium ions. In Poltva have been considerable (3–6 times) exceeding the TLV for COD and BOD5, ammonium salt 8.4 times, total iron – 4.3 times, nitrites – in 6.75 times, suspended solids – 3.3 times, phenol – at 2.45 times. Therefore, the section of the city Buzka to the city Kamenka–Bug, Radekhiv bridge river water is not suitable for any water use. The self–cleaning of the water is happening within the district is and the second point of monitoring shows these indicators are within limits. The largest source of organic pollutants and nutrients into Western Bug River is the river Poltva. Insufficiently treated sewage of Lviv increases the level of water contamination. In the district however there are also a source of pollution of surface water with ions of ammonium and iron. For their identification the further observation are required.

Abstract The Water Framework Directive introduced an ecological approach to the assessment and classification of waters. The part of the assessmentare macrophyte - based methods used in the evaluation of the ecologicalcondition of rivers in respect of biodiversity. The Macrophyte Method for River Assessment has been used in Poland since 2007 and provides us with an information about ecological state of the rivers. Presented analyses were aimed to describe macrophyte development in the sandylowland type of river in the Silesian Upland. The assessment was made for lowland Pszczynka River (45.8 km total length, total catchment area 368.3 km2), which is a left-bank tributary of Vistula River. At the selected 10 research sections of the river (100 m each) the composition of macrophytes and abiotic conditions of the river were described. The paper presents the results of preliminary assessment of ecological condition of Pszczynka River on the background sources of substances discharged to the riveralongits course. Macrophyte Index for Rivers (MIR) was calculated based on the results of the research - river bed surface coverage by the particular plant species. The MIR limit values were used to determine the class of water quality in the examined river. Overall, the ecological status of Pszczynka River was rated as moderate and its water classified as Class III of water quality.

Concentration Levels

In a full scale experimental study, raw sewage from the City of Suez, Egypt was treated using a stabilization pond system. Fish grown in the treated sewage was compared with fish from one of the farms which receives contaminated surface water in Lake Manzala. Organochlorine pesticides were detected at higher levels in fish from Lake Manzala farms, than in fish reared in the treated sewage of the City of Suez. The highest levels were due to p,p'DDT and its metabolites, followed by Lindane and HCB. Furthermore, the concentrations of Pb and Cd were significantly higher in the fish from the Lake Manzala farm, than in the fish from Suez. In addition, the concentration levels of Pb and Cd in the fish from Lake Manzala exceeded the international contaminant limits for human consumption. In general, fish grown in this region have high levels of pesticides and metal contaminants. It is interesting to note that in spite of possible cultural bias against fish grown in treated sewage effluents, have lower levels of toxic chemicals than some of the marketed fish, harvested from polluted surface waters.

Diatom metrics can be used to identify the ecological status of water bodies due to their good responses to anthropogenic disturbances. Our study is aimed to use diatom metrics developed from different ecoregions for assessing the ecological status of 11 surface waters in the south-east of the Gaziantep catchment (Turkey). Ecological characterizations of the sampling stations were introduced by Trophic Index Turkey (TIT), Trophic Index (TI), and Eutrophication and/or Pollution Index-Diatom (EPI-D). According to TIT and TI, Karkamış Reservoir had a good ecological condition while it had high ecological status based on EPI-D. This good ecological condition was approved by the presence of pollution sensitive species (e.g., Cymbella affinis, Encyonema minutum, E. silesiacum, Cymbopleura amphicephala, and Navicula radiosa) and relatively low nutrients. Kayacık (TIT ranging 3.15–3.23) and Hancağız (TIT = 3.35) reservoirs had poor and bad ecological conditions, respectively. High nutrient, conductivity, and pollution-tolerant species (e.g., Nitzschia amphibia, N. palea, N. umbonata, N. linearis, N. phyllepta, Tryblionella calida, and Pinnularia brebissonii) supported the ecological statuses of the Hancağız and Kayacık reservoirs. The first two axes of canonical correspondence analysis explained 0.943 of relationships between diatom species and explanatory variables. Explanatory variables, e.g., calcium, conductivity, orthophosphate, nitrate, nitrite, sodium, pH, and sulfur, had strong impacts on the distribution of diatom assemblages among the sampling stations. TIT and TI separated ecological statuses of sampling stations in the south-east of the Gaziantep catchment, which correlated well with the evidence of water chemistry and response of diatom assemblages.

Purpose of the work is to characterize the geo-ecological condition of the reservoirs in Lviv in order to develop recommendations for the protection, conservation and enhancement of their functional use. Methods. Field, cartographic, historical, analysis and synthesis. Results. The geo-ecological state of modern reservoirs of Lviv has been investigated. Water pollution of represented reservoirs has been analyzed according to the fund and statistical materials. In the course of the field researches the physical parameters of the water condition have been analyzed, sources of pollution of reservoirs, clogging and overall assessment of coastal water protection strip shave been identified. Most of the reservoirs of Lviv are characterized by littering of the coastal strip, recreational impact, proximity to roads and residential buildings. The color of the water in the majority of the reservoirs is grayish-yellow, the transparency of the water is low, the smell is marsh or earthy-grassy. Ten of the twenty-three reservoirs under study have strong and over-eutrophication. In summer, some are completely overgrown with algae. The condition of the basin in 70% of Lviv reservoirs is natural. This contributes to the additional intake of pollutants from the catchment area. Ponds where the basin is covered with an artificial surface (mainly concrete) have better water quality. In particular, Levandivskyi has become the only one to have clean water at the beginning of 2019. In recent years, the water reservoirs of the city have been significantly shallow, due to the construction of catchment areas and the discharge of rainwater to the general sewer. Conclusions. Irrational use of city reservoirs leads to water pollution, siltation and overgrowth of urban reservoirs, rapid eutrophication, clogging, etc. Reservoirs near leased restaurants and recreational facilities are in the best condition. The ponds located in park areas (Stryiskyipark, Pohulianka, Shevchenko-ethnopark, Piskovi Ozera) are in a satisfactory geo-ecological state. The most neglected are the reservoirs of former industrial enterprises, which are under control of district administrations. Taking into consideration the multifunctional importance of reservoirs for the city, recommendations have been developed to improve their geo-ecological state, mainly they are organizational (monitoring the status of reservoirs, introduction of ecological passport of the reservoir, increasing control), technical (separation of rain and municipal sewage, technical care), educational (stands, eco-actions, festivals) measures.

The article presents an analysis of water monitoring organization in the Sumy region. The reform of water resources management has placed the main burden on the implementation of the state water policy and ensuring the proper ecological condition of the water basin at the regional level of management. The European approach in the field of water resources management pays attention to water monitoring, which is an integral part of the state system of environmental monitoring in Ukraine. An analysis of implementation the basin principle in the region had been conducted. There are two sub-basins in the region: Desna Sub-Basin and Middle Dnieper Sub-Basin. Within the Desna sub-basin 121 massifs of surface waters have been identified, within the middle Dnieper sub-basin 230 massifs have been identified. The analysis of monitoring data on the state of surface waters, on the organization of monitoring of transboundary watercourses is carried out. The study found that farms have a significant impact on the condition of rivers. Due to the aggravation of the political situation, monitoring of transboundary watercourses is carried out only on the territory of Ukraine. The beginning of the introduction of a new approach to monitoring in Sumy region lays the foundations for the accumulation, systematization of data on the state of surface water bodies with the subsequent possibility of analyzing the existing situation with effective management decisions to achieve "good" ecological status of river basins.

Abstract Stawy Dojlidzkie (The Dojlidy Ponds) are located in the north-eastern part of Poland, near the capital of the Podlasie province, in Białystok. The Dojlidy Ponds (DP) are a complex of more than 20 reservoirs arranged adjacent to one another in an area of about 140 hectares. The largest recreation reservoir (Plażowy) is located within the city limits. Its total area is 34 hectares, it has a capacity of 597 040 m3 and a maximum depth of approximately 2.5 m. DP are supplied by a tributary of the Dojlidy Górne and the River Biała, the principal river of Bialystok. Water tests of a limnic and lenitic character in the upper part of River Biała catchment in Bialystok were conducted from March to October 2014. Referring the obtained results to the actual norms, it can be concluded that most of the parameters analyzed in DP can be assigned to the first class of surface waters. Exceptions were the iron ions, orthophosphates (SRP), total phosphorus (TP), Kjeldahl nitrogen, and also water color and DOC. According to the evaluation of trophic status, the water of DP is eutrophic. The average value of TSI was 55 in the water of the tested objects. The obtained results show that the ecological status of water in the largest pond within the DP complex, in accordance with, the Ecological State Macrophyte Index (ESMI) represent to the good state.

Purpose. Determination of the main factors of anthropogenic impact of the urban system of the city of Lutsk on the river basin of the river Sapalaivka and assessment of the ecological condition of the river on the basis of MIR "Macrophytic index of rivers". Methods. Comparative-geographical, generalization, systematization, statistical, comparative-analytical, descriptive, cartographic. Results. In the Sapalaivka River, 21 indicator species of macrophytes were found in the surveyed test areas, among which - 8 plants belong to dicotyledons, and 13 plants belong to monocotyledons, using which the MIR values ​​were calculated. Depletion of macrophyte species composition from 15-16 in test plots 1 and 2 to 2 species in test plot 3 indicates deterioration of the ecological condition of the river and the emergence of unfavorable conditions for macrophyte habitats. On the territory of the city, the section of the Sapalaivka riverbed, from the beginning of Potapova Street to the mouth, is mostly canalized, the species composition of macrophytes is depleted here and there is a specific smell of sewage. The part of the river that flows in the city (before Potapova Street), which was renaturalized in 2012-2016, has a richer species composition of macrophytes. Outside the city, the Sarpalaivka river basin is in good condition, as evidenced by the species composition of flora and fauna, as well as the intensive development of higher aquatic vegetation. Conclusion. As a result of the calculated ecological index of macrophytes MIR it is established that the water quality in the river Sapalaivka on the test site № 1, belongs to the II class, category - good and by trophic status is mesotrophic; on the test site № 2, belongs to the III class, category - satisfactory and eutrophic in trophic status; on the test site № 3, belongs to class IV, category - poor and trophic status is polytrophic. It is advisable to carry out further environmental measures, especially in the lower reaches of the river, in order to eliminate sources of water pollution, and to monitor the ecological status of the reservoir in order to restore the species composition of macrophytes and the ability to self-clean.
