Abstract The purpose of the paper was to assess the changes in the concentration of selected metals in the bottom sediment and interstitial water of the River Chotla in northwest Poland. The research was conducted on the river section flowing through Zaspy Małe and a salmonid fish breeding farm. Samples of water and bottom sediment were taken in four control and measurement points, located above and below the village and on a backwater above the trouteries and below the fish breeding ponds. The pH and the concentration of the metals potassium, iron, calcium, manganese and zinc were determined in the water and sediment samples. The lowest concentrations of the metals were found in the samples collected above and below Zaspy Małe, while the highest concentrations of metals in the water and sediment were found in the samples taken in the backwater, above the fish breeding ponds. Exceptions were calcium and potassium, with the highest concentrations of metals in the water being found in the samples taken below the fish breeding ponds. The content of metals in sediments of the analysed section of the River Chotla was mainly determined by the content of organic matter, which varied as it is dependent on water accumulation processes and the operation of nearby fishery facilities. The slightly alkaline pH facilitated long-lasting accumulation of metals in sediments.

Objective of research: to perform the parasitological monitoring we have to study the parasite fauna in fishes from different fish farm factories, calculate the index of similarity, estimate the influence of abiotic and biotic factors on the ecosystem of fish-breeding reservoirs. Materials and methods: parasitological monitoring of factory fish farms was conducted by the method of complete and incomplete parasitological examination taking into account the data obtained from various fish-breeding reservoirs. Results and discussion: the parasite fauna of cyprinid fishes is represented by 56 species, carriage of causative agents of parasitic diseases in fishes is detected. Index of similarity of parasite fauna in carps has been studied and typification of agricultural reservoirs carried out. Index of similarity between the parasite fauna in carp and herbivorous fish was 22–33 %, carp and rough fish - 18–30,7 %. Influence of abiotic (oxidability, reduction of oxygen and nitrogen ammonia concentration, mineralization) and biotic – anthropogenic factors (violation of processing technologies, veterinary and sanitary rules of fish transport and fish farming operations) on fish infestation with parasites was studied. The role of parasitological monitoring in prevention and elimination of fish diseases was shown.

Exchange Flux

Overlying water and sediment samples were collected from 11 locations in Ulansuhai Lake in June of 2012 to determine the concentration of dissolved inorganic phosphorus (DIP) in the interstitial water, overlying water and sediment and to estimate the diffusion flux of DIP at the sediment–water interface. The DIP levels in overlying water were 0.004–0.185 mg/L (average = 0.062 mg/L), while they were 0.05–0.25 mg/L (average = 0.124 mg/L) in the interstitial water in the 0–2 cm surface sediment. Moreover, the annual mean exchange flux of DIP in the sediment was between −0.092 mg/m2·d and 0.053 mg/m2·d, and this occurred via internal source action in most areas. After area weighting, it is estimated that the exchange capacity of DIP at the sediment–water interface of the Ulansuhai Lake is 1.30 t/a. These findings indicate internal loading of phosphorus in sediment of the Ulansuhai Lake; thus, the diffusion of DIP in the interstitial water has effects on the lake, with a degree of influence of 2.7% to 81.5%.

The main anthropogenic factors of chemical and toxicological pollution of decentralized water-supply sources in rural settlements are examined. Complex estimation of water pollution level is made and the dependence of subsoil waters quality from season changes is elicited on the example of countryside within Berezany district Ternopil region. Berezhany district is mostly agricultural and that’s why agriculture becomes one of the biggest polluters of water resources especially subsoil. Dangerous source of water pollution, especially in the period of spring flooding and rainfall flooding are diffuse runoffs from agricultural areas/ in three to four times more nutrients and suspended solids are imposed from them than from natural areas. In the qualitative composition (cation and anions content mineralization ) among subsoil’s waters  of Ternopil region, that are used for water-supply, essentially dominate bicarbonate-sulfate calcium-sodium waters with mineralization 0.2–0.8 g/dm3. Especially in Berezhany district subsoil fresh waters have bicarbonate-sulfate calcium-sodium composition with common mineralization of 0.5–0.7 g/dm3. There are 3432 artesian wells in the region, including 2679 in the countryside and 753 in towns and 74296 mine pits. It is found that on this territory low concentrations of nitrites during the whole period of research are marked. Except for isolated cases of its growth: in the village Zhukiv (to 0.02 mg/dm3) in autumn and Posurhiv (to 0.04 mg/dm3) in spring, that are explained by the increasing of quantity of fall-outs and respectively, growth of runoff from agricultural lands. Small concentrations of nitrites in groundwater’s on the district territory (less more than 0.01 mg/dm3) are due to their extreme instability. They are oxidized, moving to the most stable inorganic nitrogen – nitrates. Concerning nitrates, their high levels with gradual growth from spring to autumn is found. In the village Zhukiv the figure does not exceed the norm, except in autumn, where it is 52.35mg/dm3. Significant increase of nitrates concentration on the territory of these villages in autumns is explained by the fact, than during the rains polluting substances penetrated into groundwater’s, that drained from fields, where nitrogen fertilizers were given. In summer this increase can be explained by fertilization. Receiver results speak about poor state of ground waters as the sources of decentralized water-supply due to increasing of nitrate contents in these objects. It is shown that effluents and fertilizers that are given into the soil, make the most influence on the quality of water from underground sources. It is also founded the increasing of contents of nitrites, nitrates, chlorides, sulphates in spring during snowmelting and in autumn during rains. Considering the excess of nitrates norm in ground water it is necessarily control making of nitrogen fertilizers into soil. It is necessary to conduct purification  of drinking water before its usage. It is obviously that on the areas with higher percentage of “unstandard” water the morbidity of cancer is higher. The effect of influence of water with higher contents of nitrates increases against the background of malnutrition that is particularly in the current crisis period of life.

Natural And Anthropogenic Factors

This article is devoted to the study of one of the most significant problems of hydro-ecology, pollution of rivers and other water bodies through natural and anthropogenic factors. Without solving this problem, it will be extremely difficult to provide the population with safe drinking water, to allow the normal development and habitation of fish and other aquatic organisms in water bodies, and to protect the environment and its integrity. During our study of the Bazavluk River, a hydrological study was carried out, physical and geographical indicators were measured and studied, conclusions were drawn, and methodological recommendations were developed for the preservation and restoration of the Bazavluk River, which is necessary for economic water supply, fisheries, and irrigation. The reservoir has a length of 157 kilometers, and the area of ​​the basin is 4,200 km2. The river valley has a trapezoidal shape up to 2 kilometers wide. The river is winding; the lower part the left bank is sloping in contrast to the right, which is steep along the entire length of the reservoir. The width ranges from 8 to 10 meters, and the average depth is 1.5 meters. The slope of the river is 1.3 m/km. The Bazavluk River originates southeast of the village of Kozoduba, and flows from north to south (partly to the southwest) and flows into the Dnieper (Kakhovka Reservoir) 199 kilometers east of the village of Hrushivka. This reservoir has 6 main tributaries, the largest of which are: Rekalova (right, 14 km), Balka Koshovata (left, 16 km), Vodyana (right, 15 km), Bazavluchok (right, 24 km), Solona (left, 56 km), Kamyanka (right, 88 km). The ice crust usually appears in December and disappears in late February-early March. It mostly flows through the plain steppe, but sometimes there are places with high rocky shores. In dry years, shallow areas can dry out and freeze. Some water resources are used by local residents who have settled nearby to irrigate agricultural land.
