The aim of this work was to be traced during the summer and autumn of 2009 the level and dynamics of changes in the waters of the Port of Szczecin General docks parameters water quality. In the work of the General indicators of water temperature, were numbered: pH, BOD5, COD-Cr, Cl-. All the markings and the calculation was performed according to the methods recommended by Polish Standards, applying analytical procedures described in by Dojlido, Elbanowska, Hermanowicz. Port of Szczecin is located on the Oder river and its right shoulder Regalicy. Is located in the western part of the port of Szczecin, in the northern part of the Valley of the lower Oder river on May. The port consists of water bodies which are branches of the Oder river and the channels: Mielenski, Grabowski, Dunczyca Channel Figh, Wroclaw, Parnica, Channel Channel Debicki and Lake Dabie. Trying is water were collected by PN/C-04632.03 with a depth of about. 2 m below the water surface. The temperature at the place of sampling were numbered, pH. Collected water samples were fixed In accordance with the recommendations in the Polish Standard-PN/C-04632.04. Other indicators for the quality of the waters have been tagged within 24 hours from the moment of download attempts. The quality objectives was evaluated according to the criteria recommended to evaluate inland surface waters referred to in regulation of the Minister of the environment of 11 February 2004 on the classification for the present status of surface water and groundwater, how to conduct monitoring and how to interpret the results and presentation of these waters. Due to the exposure of the docks the port Szczecin on the pollution associated with cross-what are the cereals, ores, oil, cellulose, carbon, iron, general research evaluation of the water quality of these pools, you can assess the status of water In order to keep these waters.

All the markings and the calculation was performed according to the methods recommended by Polish Standards, applying analytical procedures described in. by Dojlido, Elbanowska, Hermanowicz. Port of Swinoujscie is a sea port located on the Gulf of Pomorska, on the southern coast of the Baltic Sea, on the islands of Usedom and Wolin. The Port is located at the Swina, In Swinoujscie, West Pomeranian Voivodeship. The port can be placed on ships with a maximum length of 42.0 m and width 260,0 m, draught 12.8 m. The tides in the Harbor, but the water level fluctuations are possible with sudden currents entering and outgoing, which depending on the direction of prevailing winds and reaching speeds of up to 1.5 knots. At the entrance to the port at the West breakwater, It is Western. The primary function of the port of Swinoujscie is the transshipment of cereals, ores, oil, paper, cellulose, general cargo, coal, iron. Trying to test water were collected by PN/C-04632.03 with a depth of about. 2 m below the water surface. The temperature at the place of sampling were numbered, pH.

Opis:
The sorption of divalent copper, natural sorbents of kaolinite and montmorillonite clays and carbon sorbent was studied on model solutions under static conditions. Quantitative characteristics of sorption process of copper ions were obtained. The degree of extraction of copper ions from solution was investigated, depending on the concentration of the initial solution and the weight ratio of the sorbent and volume of treated solution. The magnitude of sorption increases along with the increase in the volume of copper sulfate solution with a concentration of 0.02 M at a constant sample of sorbents. A higher carbon sorption capacity of the sorbent, in relation to ions of copper, was compared to kaolinite and montmorillonite clay. A higher sorption capacity of the carbon sorbent with respect to copper ions is established in the comparison with kaolinite and montmorillonite clay.

Opis:
The aim of the study was to determine Dissolved Organic Carbon (DOC) and Biodegradable Dissolved Organic Carbon (BDOC) concentrations, as well as the correlation between them, in the river water of the Strug basin located in the Carpathian Foothills. The Strug river's hydrographic basin was chosen for the study as it is a typical catchment area, which allows ease of measurement. DOC concentrations in the streams (tributaries) and the Strug ranged from 2.71 to 4.88 mgC/dm3 and from 3.62 to 4.19 mgC/dm3 , respectively. BDOC concentrations in the streams and the Strug ranged from 0.40 to 1.09 mgC/dm3 and from 0.64 to 0.77 mgC/dm3 , respectively. BDOC, expressed as the percentage of DOC (%BDOC) ranged from 14.76 to 24.78% in the streams, and from 17.68 to 20.11% in the Strug. The procentage of BDOC is independent of DOC concentrations. The season of the year and the size of the watercourse had the greatest impact on DOC and BDOC concentrations.

Opis:
In order to solve the problem of providing the population with high-quality drinking water, preference is given to the use of groundwater deposits, which differ from surface sources in better quality and are more protected from man-made influences and climate change. Thirty-seven existing groundwater deposits are used for drinking and technical water supply in Lviv region. The distribution of groundwater in the region is very uneven, and in the Eastern Carpathians they are almost non-existent. The main factors of groundwater pollution in most of Ukraine are municipal sewage, livestock effluents, unorganized warehouses for storage of industrial waste, fertilizers and pesticides and other local objects that affect the state of groundwater. The gradual reduction of mineral fertilizer and pesticide usage has led to some improvement in the quality of groundwater, but for some agro-industrial areas the presence of residual pesticides and nitrogen compounds in groundwater remains a relevant problem. This year, there was an increase in the use of mineral fertilizers compared to last year. The aim of this work was to study the compliance of the maximum allowable concentrations of hydrochemical parameters of the wells of the Stryi water intake and to determine the potential impact of anthropogenic factors on water quality. The compliance with the sanitary and hygienic requirements of the hydrochemical parameters of water in the wells of the Stryi water intake was analyzed. The regularities of their changes as well as the presence of wells that have a potentially unstable chemical composition and are prone to deterioration of water quality were determined. The results of studies of related to the impact of self-treatment processes in the river Stryi on the quality of water intake in the city of Stryi showed that the drinking water from artesian wells is of high quality and now there are no negative effects of river water in the Stryi basin on groundwater deposits. The quality of river water is satisfactory for its use in domestic and drinking water supply and for recreational purposes.
