Concentrations and loads of N-NO3, N-NH4, PO4 and BOD5 in waters of the upper Dunajec (in the years 1985-1998) Loads of N-NO3, N-NH4, PO4 and BOD5 carried in surface waters of the upper Dunajec catchment basin (at the section in Krościenko) in the years 1985-1998 are presented in this paper. Water quality of the Biały Dunajec (in Szaflary), Czarny Dunajec (in Ludźmierz) and Dunajec (in Krościenko) was characterised. Annual loads discharged from the area per km2 of the catchment were calculated from mean annual flows (SQ) and concentrations of studied components in river waters. Concentration of N-NO3 in waters of the Biały Dunajec was more than two times higher and that of phosphates - over seven times higher than the respective concentrations in the Czarny Dunajec and Dunajec. Different population density, numerous tourists and low level of water and sewage infrastructure were responsible for these differences.

Scientific Base

The article considers the problems of irrigation water quality in Central Asia through hydroecological monitoring. Practical and scientific recommendations for solving these problems are offered. There are noted the necessity of development of scientific base of researches on all aspects of water quality and protection of water resources; adoption of laws and administrative documents on protection of waters and improvement of their quality; performance of various engineering, technological actions. The hydroecological state of surface waters of large irrigated areas of the Amudarya river basin was studied for regieon: Surkhandarya, Kashkadarya, Khorezm and irrigated zones of the Republic of Karakalpakstan. It is noted that the process of salinization of irrigated lands is dangerous for the region. According to the calculations 50...55 million tons of various salts are came to irrigated annually fields. This is the reason for the deterioration of the hydrological state of irrigated agriculture in the region.

The Difference

The use of surface waters such as rivers for domestic, agricultural andindustrial purposes have made them vulnerable to pollution leading to impairedwater quality. The water quality of Lahug River in Cebu City was evaluated usingcoliforms as indicators, in relation with physicochemical parameters such as biological oxygen demand (BOD), conductivity, dissolved oxygen (DO), nitrate,pH, phosphate, salinity, temperature, total dissolved solids (TDS) and totalsuspended solids (TSS). Sampling was done once a month from November 2011to April 2012 in three stations covering the upstream, midstream and downstream.The multiple tube fermentation technique was used for the analysis of coliforms.The level of these indicator bacteria increased from the upstream towards thelower reaches of the river especially in the months of February to April; however,the difference in values across time was not significant. This implies that therewas a continuous fecal pollution in the river. There were no statistically significantcorrelations between FCs and TCs with the physicochemical parameters. Anegative relationship was observed among FCs and TCs with pH, TSS, DOand nitrate (p>0.05). These results suggest the presence of sewage and organicpollutants in the river.Keywords: Aquatic Ecology, water quality, coliform, physicochemical parameters,experimental design, Philippines

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 the port Świnoujście general parameters pools 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, Elbanowską, Hermanowicz. Port of Świnoujście is a sea port located on the Gulf of Pomorską, on the southern coast of the Baltic Sea, on the islands of Usedom and Wolin. The Port is located at the Świna, in Świnoujście, 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 Świnoujście 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. 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 Świnoujście 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.

Abstract The aim of the study was to determine changes in water quality, including chemistry of outflow from two rivers: Łutownia and Perebel located in the Białowieża Primeval Forest. Water chemistry was investigated once in every three months in the years 2011-2014. Catchments differed in forest cover and habitat types. The results of the analysis of river waters were compared with the limit values for each class of water quality as settled by the legal standards. It was found that the quality of the water in rivers declined due to high concentrations of carbon and nitrogen organic forms. In general, there was observed a decrease of the concentration of organic nitrogen and an increase of the concentration of mineral nitrogen, especially in the Perebel catchment area.
