The pH dependence of adsorption reactions of cationic metals is due, in part, to the preferential adsorption of the hydrolyzed metal species, in comparison to the free metal ion (McBride, 1977; McLauren and Crawford, 1973; Davis and Leckie, 1978; Farrah and Pickering, 1976a,b; James and Healy, 1972; McBride, 1982; Cavallaro and McBride, 1980; Harter, 1983). The pH of the soil system is a very important...
Metals added to soil will normally be retained at the soil surface. Movement of metals into other environmental compartments, i.e., ground water, surface water, or the atmosphere, should be minimal as long as the retention capacity of the soil is not exceeded. The extent of movement of a metal in the soil system is intimately related to the solution and surface chemistry of the soil and to the specific...
Once freshwater has been used for an economic or beneficial purpose, it is generally discarded as waste. In many countries, these wastewaters are discharged, either as untreated waste or as treated effluent, into natural watercourses, from which they are abstracted for further use after undergoing "self-purification" within the stream. Through this system of indirect reuse, wastewater may...
The article presents an application of multi-criteria analysis for selection of the best treatment technology and the best technical solution to the running of a large and a small wastewater treatment plant. The calculations performed for two plant capacities and for various effluent standards are based on a compromise programming method. The effluent standards considered for the smaller plant are...
In spite of widespread support from the population of most member countries for European Union policy, including support for sustainable development, in many EU countries, the levels of acceptance of new environmental protection programmes have been and, in particular in new member states, still are considerably low. The experience of the countries which were the first to implement union directives...
Models relating chlorophyll to nutrients and Secchidepth to chlorophyll using data from nearshore coastal waters of Baltic Sea were successfully developed. The models suggest that phosphorus is the primary limiting factor for phytoplankton in the nearshore coastal waters of Baltic Sea and that total phosphorus concentration accounts for 65% of the variance in chlorophyll concentration.The models also...
A review of EU legislation and national rules applicable to the assessment of the quality of the marine waters of the Baltic Sea in Poland. A review of the procedures prescribed by law, highlighting some inconsistencies, and pointed to the importance of the innovative approach of the EU Water Directive towards assessing water quality, which now should be based primarily on assessing the health hydrobiont...
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 Swinoujscie general parameters pools water quality. In the work of the General indicators of water temperature, were numbered: pH, BOD5, CODCr, Cl-. All the markings and the calculation was performed according to the methods recommended by Polish Standards,...
A pot experiment on an acid brown soil was conducted in 1998-2001. Three multicomponent fertilizers were applied: Polifoska 8, Polifoska 15 and Polimag 306, Travit at the rates of 0.5; 1.0; and 1.5 g N per pot. The total forms of potassium were determined in dry matter of perennial ryegrass with the use of ASA method. The contents of these elements were higher in the fertilized variants as compared...

Urbanization is the cause of many changes which is taking place in the environment, including those found in the catchment. A pot experiment on an acid brown soil was conducted in 1998-2001. Three multicomponent fertilizers were applied: Polifoska 8, Polifoska 15, Polimag 306 and Travit at the rates of 0.5; 1.0; and 1.5 g N per pot. The total forms of nitrogen were determined in dry matter of perennial...

The progress of civilization as well as the growing up process of transformative environment adversely affect individual environmental elements in the soil. In recent years the increasing pollution of the atmosphere causes more and more interest in the science of the substances contained in it and merge back to the surface of the Earth. Of great importance for the environment have the substances contained...
A pot experiment on an acid brown soil was conducted in 1998-2001. Three multicomponent fertilizers were applied: Polifoska 8, Polifoska 16 and Polimag 306, at the rates of 0.5; 1.0; and 1.5 g N per pot. The total forms of cadmium were determined in dry matter of perennial ryegrass with the use of ASA method. The contents of these elements were higher in the fertilized variants as compared to the...

Wytwarzanie odpadów jest nieodłącznym elementem działalności bytowo - gospodarczej człowieka. W Polsce najbardziej rozpowszechniony jest system zarządzania typowo ekstensywny, to dlatego, ponieważ odpady są prawie w całości składowane na składowiskach odpadów. W czasie eksploatacji składowiska odpadów komunalnych oddziałują one na poszczególne elementy środowiska przyrodniczego tj.: powietrze, glebę,...

Celem niniejszej pracy było prześledzenie w okresie od 2004 do 2008 roku poziomu oraz dynamiki zmian w wodach basenów portowych Portu Świnoujscie parametrów ogólnych jakości wód. W pracy oznaczano wskaźniki ogólne wody: temperaturę, pH, ChZT-Cr, BZT5, Cl-. Wszystkie oznaczenia i obliczenia wykonywano według metod zalecanych przez Polskie Normy, stosując procedury analityczne opisane m.in. przez Dojlido,...
