The experiment was carried out on 4 pregnant goats at age 23 years. Changes in basic indices of renal function were analysed in the scope of hydroelectrolyte management in the consecutive five months of gestation. Blood and urea samples were collected fortnightly during the first three months of gestation, and weekly during the remaining two months. The analyses included urea volume and glomerular filtration rate, as well as blood plasma concentration, clearance, tubular reabsorption and excretion of sodium, potassium, chlorides and total osmotically active substances.

Lake Gardno, as the central object in the hydrographic structure, is under the influence of land and sea waters. This results in the situation where the lake together with its direct catchment forms a unique geoecosystem which differs from other inland reservoirs performing the role of local or regional recipients in hydrographic systems, in terms of the quality of water as well as the rate and dynamics of transformations occurring in it. This is an effect of overlapping influences of waters inflowing from the catchment and intrusions of sea waters. During intrusions, waters of higher salinity occur and remain during the greater part of the year in the whole water body of the lake, which is conditioned by the shape of the basin facilitating the penetration of salty waters. It was established that the water coming from intrusions remains for at least several days. There is also evidence from reconnaissance measurements that the retention is longer. The easiness of penetration and long retention period result in the fact that only periodically the desaltation effect of potamic waters leads to an almost complete desaltation of water in the whole basin of the lake Gardno.

Between May and October of 2003, mineral composition of surface (0.5 m deep) and bottom (5.0 meters) waters, at measurement stations in north-western and south-eastern parts of Great Lagoon (Szczecin Lagoon), have been studied. Total concentrations of ionic macrocomponents: Na+, K+, Ca2+, Mg2+, Cl-, HCO3 - , SO4 2- have been determined. Differentiation of ionic composition and changing level of concentrations of ionic macrocomponents in waters, depending on location of measurement station, depth of water sample collection and time of examination, have been proved. Bottom waters in south-eastern part of Great Lagoon had highest salinity level, whereas surface waters in the same location had lowest degree of salinity. Taking into consideration relatively small number of measurements, authors of present paper regard outlined investigations as diagnostic and obtained conclusions as preliminary ones. Towards substantial variability in ionic composition and magnitudes of concentrations, it is practically impossible to forecast and define values of concentrations of individual ionic components and general salinity degrees, basing on chlorides concentrations, what was often pursued, until now.

Soil salinity is the one of the most important abiotic factors influencing the growth, development and yields of crops. However, it is difficult to determine exact concentrations of salt which cause soil salinity. Salinity threshold levels depend on a crop species, variety, developmental stage and environmental factors. This paper presents the results of an experiment on the effect of different soil concentrations of NaCl soil on several oxidation stress parameters, such as catalase and peoxidase activity, content of ascorbic acid, phenols and flavonoids in bean plants. A laboratory pot experiment was carried out on samples of light silty loam containing 1.2% of humus. Pots were filled with 1 kg soil samples each, to which NaCl solution was added in doses 10, 30 and 50 mM kg-1. Each pot was seeded with 7 seeds of cv. Aura bean. The plants grown in soil without NaCl were the control. On days 14, 21 and 28 green parts of plants were collected for determinations of catalase and peroxidase activity by colorometry as well as the content and flavonoids, phenols, ascorbic acid and chloride concentration by Mohr’s method. The results show that chloride concentration in bean plants increased at higher of NaCl concentration in soil. The activity of the antyoxidative enzymes such as catalase and peroxidase in bean plants, on sampling days, was higher as the chloride concentration in plants increased. Non-enzymatic antioxidants: flavonoids, phenols and ascorbic acid content during the experiment showed different changes with relation to the chloride content, but in all the trials ascorbic acid content was significantly positively correlated whereas the content of phenols was significantly negatively correlated with the chloride content in plant tissues.

The water intake situated at Rybacka Street in Wolin was established in the beginning of the 20th century. It is situated in the close vicinity of the existing apartment and business buildings and the water and sewage systems as well. On the fenced parcel ca 50x80 m besides the objects of: – building of the water-supply station, – warehouse – workshop building with sanitary facilities, – household building, – building of the current generating plant, are situated the deep-water wells No. 6 and No. 9 now in the operational use. The other deep-water wells being now in the operational use are the well No. 10 situated at Rybacka Street in the distance ~ 90 m from the intake parcel border as well as the well No. 5 situated in the distance ~ 220 m from the parcel border.
