Opis:
The chemical composition of water from two peatlands was investigated. Both peatlands, which are nature reserves, are located in central Poland in the Widawka and Rawka River valleys. The study concerned groundwaters, peat waters from different depths, and waters from draining ditches. The research permitted determination of the hydrochemical zoning of the peatlands resulting from the complex character of the water supply. The hydrochemical interpretation of surface waters outflowing alongside the ditches, in terms of their similarity to particular zones, provides an insight into the water-feeding structure of the peatlands. In the evaluation, hydrochemical indicators were applied, which have been used in hydrogeological studies. They are based on equivalent concentrations of the major ions: sodium, calcium, chlorides, and sulphates, selected from other hydrochemical elements by means of principal component analysis (PCA), conducted individually for each peatland. The analyses showed a high contribution of unconfined and confined groundwaters to the water supply, with clearly distinguishable zones, in terms of their transit through the structures of the peatlands.

Opis:
Hydrochemical indicators are widely used for assessment of groundwater chemistry. They were established mainly for mineral water in order to understand their origin and chemical classification. In the case of fresh water, they are used occasionally because quality classifications are based on concentrations of individual components and physical properties in relation to the permissible standards established for water intended for human consumption. Natural in Polish climate, bicarbonate-calcium and bicarbonate-calcium-magnesium waters are commonly used for drinking. In many places, ions emitted from pollution outbreaks have already caused chemical changes of water and it is often the first symptom of their contamination. The author has evaluated the scope and trends of these changes in the groundwater of the Holy Cross region in Poland using the bicarbonate and calcium-magnesium indicators.

Opis:
The paper describes taxonomic composition of leeches (Hirudinea) in the strongly anthropogenically altered upper reaches of the Stepnica River in Western Pomerania. The numbers of respective species of the Hirudinea were analyzed in the context of such environmental factors as: instantaneous flow, dissolved oxygen content, and calcium content. It was noted that most leech species inhabited the headstream, and factors deterrent to their occurrence included the presence of hydrogen sulfate and siltation.

Inhulets river
Opis:
The dynamics of hydrochemical parameters of surface waters from the upper, middle and lower reaches of the river was analyzed. On the basis of the analysis of temporal and spatial monitoring data, a comprehensive assessment of the environmental status of the Inhulets river (Ukraine) waters by hydrochemical indicators was carried out. The study performed a comparative analysis of the river water quality assessment using different methods: an integrated assessment based on the calculation of water pollution indexes, pollution rate. A result of the evaluation of water quality in certain classes: in terms of ammonium ions and BOD5 – III quality class, the water is slightly polluted; phosphate content – V quality class, water is very low in the bottom; according to the content of suspended solids, in phosphates and BOD5 – III class of water quality, water is polluted; by a concentration of chlorides – V class of quality, degree of purity – very dirty; the value of suspended solids and chlorides – III class; in terms of the sulfate content – IV class. In general, the very excessive concentration of substances in the middle course remains stable, the environmental state is poor (quality class IV).

Inhul river
Opis:
On the basis of the analysis of wide temporal monitoring data, a forecast of the integrated hydrochemical indicators of the waters of the Inhul river (Ukraine) was carried out. The performed analysis was also the basis for the determination of a mathematical model of natural fluctuations of the indicators studied. The determined sinusoidal dependence of the integrated water quality indicators allowed determining the average time of fluctuations concerning the processes of self-organisation of river waters. In practice, the developed mathematical models may constitute a valuable support and supplement to the existing models in the field of prediction of self-organization processes of river waters. They may also contribute to even more effective minimization of undesirable effects of anthropogenic impact on aquatic ecosystems.
