Results of Surface Water Quality Monitoring of the Western Bug River Basin in Lviv Region

Odnorih Zoriana, Manko Roman, Malovanyy Myroslav, Soloviy Khrystyna

Journal of Ecological Engineering

2020

Vol. 21, nr 3

18--26

The article describes the steps for organizing and conducting the ecological monitoring of surface water in order to shift Ukraine to the European standards in the field of water use and protection. The main water users-pollutants of the Western Bug River basin in the Lviv region were identified. The results of the water samples taken from the control bodies in 2018 were analyzed. A promising way to improve the work of the water basin management of the Western Bug River was proposed.

Ponds Syrenie Stawy in Szczecin - changes of selected water quality chemical indices

The possibility of using - to a wider inference - water quality test results of stream Osowka flowing through ponds Syrenie Stawy in Szczecin (NW-Poland) - in particular the concentration of dissolved oxygen (DO), electrical conductivity (EC) and the total concentrations of nitrogen (TN) and phosphorus (TP) - conducted in the years 1994 to 2014 was analyzed. The examined indices were classified according to Official Standards currently in force in Poland. Changes of water quality as it flows through the ponds were identified. Multivariate linear regression equations were calculated, endearing statistically significant relationship between successive test indicators (yi) and other indices (xi) and deadlines for measurement periods (Ti) has been made. This allowed in general to characterize water quality, determine the quality changes along the path of flow through ponds and discern what processes biohydrogeochemical within the ecosystem changes affected their quality.

Analizowano możliwość wykorzystania - do poszerzonego wnioskowania - wyników oznaczeń fizyczno-chemicznych wskaźników jakości wód oznaczanych przy określaniu stanu ekologicznego wód powierzchniowych strumienia Osówka przepływających przez Syrenie Stawy w Szczecinie (NW-Polska), tj. stężenie rozpuszczonego tlenu (DO), przewodnictwo elektrycznego (EC) oraz ogólne stężenia azotu (TN) i fosforu (TP) przeprowadzone w latach 1994-2014. Badane wskaźniki klasyfikowano według standardów aktualnie obowiązujących w Polsce w przepisach urzędowych. Oszacowano także zmiany jakości wód podczas przepływu przez stawy oraz obliczono równania regresji liniowej wieloczynnikowej, ujmujące statystycznie istotne zależności pomiędzy kolejnymi badanymi wskaźnikami (yi) i pozostałymi wskaźnikami (xi) oraz terminami okresów pomiarowych (Ti). Pozwoliło to ogólnie scharakteryzować jakość wód, określić zmiany jakości wzdłuż drogi ich spływu przez stawy oraz poznać, jakie procesy biohydrogeochemiczne zachodzące w ekosystemie wpływały na zmiany ich jakości.

Differences in the abiotic parameters of water in coastal lakes in the light of the EU water framework directive: an example of the Polish southern baltic coast

Coastal lakes have a specific hydrological regime determined by the influence of sea and inland water and the local hydrographic conditions. There are several problems concerning the protection and assessment of water quality of these bodies. The most important features differentiating coastal lakes from other lakes are: high salinity, a wide range of seasonal and short-term water quality changes, and specific aquatic ecosystems adapted to these conditions. These matters have not been sufficiently taken into account in the existing classifications and typologies of lakes in Poland. The problem has not been solved by the establishment of the adequate reference conditions and new guidelines for the classification of water status (which are being prepared according to the Common Strategy for the Implementation of the Water Framework Directive) regarding inland surface waters (rivers and lakes) and marine waters (coastal and transitional). An important issue is to define criteria which would help to distinguish all those hydrographic objects and to establish water quality standards for them.
