THE ROLE OF NATURAL BARRIERS IN THE SPREAD OF TRANSPORT POLLUTION FROM THE EMISSION LINE
Małgorzata Anna Jóźwiak, Bartosz Jachymczyk
Summary
The transport routes are filled with greenery in order to increase the attractiveness of the landscape, use of natural trees and shrubs for the exchange of air masses, mute noise, retention of rainwater and protection against exhaust and automotive pollution. In many situations, expressways run through, located on both sides of the roadway, natural forests complexes. The intensity of operating routes is very high, resulting in increased emissions of pollutants from complete and incomplete combustion of petroleum fuels and the friction of tires on asphalt road surface. These pollutants are: sulfur dioxide (SO2), carbon dioxide (CO2), carbon monoxide (CO), nitrogen oxides (NOx), tetraethyl lead, non-methane volatile organic compounds (NMVOCs), PAHs, aldehydes, dioxins, particulates, heavy metals, including chromium, cadmium, lead. The aim of the study is to demonstrate the role of trees growing along the expressways as a natural barrier to the spread of pollutants from the emission line. In the method bioindicator Hypogymnia phosodes – lichen indicator was used, which was transplanted at the designated points of research

ENVIRONMENTAL FEE – LEGAL OBLIGATION OR CONSCIOUS DUTY
Maciej Jóźwiak
Summary
Payment of fees for use of the environment, by their nature similar to taxes, is the responsibility of each person whose action may impact on the environment. There is a list of enumerated exemptions, but it should be – in principle – assumed, that everyone who uses the environment should be aware of its duty, properly calculate a fee and pay it in accordance with the statutory requirements. Penalty for lack of payment can be imposed by the competent authority of the government administrative. The penalty is independent of the obligation to pay the overdue fee. The liable person however has a right to appeal against a decision imposing such penalties.

PLANKTONIC ALGAE – BIOINDYCATORS OF THE EUTROPHICATION LEVEL OF TWO DAM RESERVOIRS: WAPIENICA AND KOZŁOWA GÓRA
Ewa Jachniak, Janusz Leszek Kozak
Summary
In this publication the qualitative structure of planktonic algae was presented. These planktonic algae spread out in two separate dam reservoirs: Wapienica and Kozłowa Góra. There was also presented the biomass largeness of phytoplankton. The estimate of eutrophication was performed by taking into consideration of the indicator taxons; there was used the classification proposing by Heinonen (1980), too. This classification considers the biomass largeness of phytoplankton. The typical taxons for oligotrophic water were observed in the samples of water taking from the reservoir of Wapienica, however the typical taxons for eutrophic water occured in the samples of water taking from the reservoir of Kozłowa Góra. The examinations concerning the average biomass of phytoplankton allowed classification the reservoir of Wapienica to oligo-/mesotrophic reservoirs, but the reservoir of Kozłowa Góra to hipertrophic reservoirs.

METHODOLOGICAL ASPECTS OF PRECIPITATION SAMPLING FOR HEAVY METALS CONTENT INVESTIGATION
Anna Degórska, Urszula Białoskórska, Dorota Typiak-Nowak
Summary
The aim of the described experiment was testing of two methods used for collecting precipitation samples at the forest (throughfall and stemflow) for heavy metals analyses. Comparison of data obtained using two methods – samples collectors made of glass and acidification of the collected samples and polyethylene collectors without acidification – has shown that the results are much smaller when standard samples were analyzed (standard samples – collected for main ions analyses). It is particularly important in case of cadmium, lead and zinc. This experiment has shown importance of proper measurement method taking into account the aim of the research, starting with samples collecting. Precipitation samples for heavy metals analyses should be collected by the collectors made of glass and after that should be acidified in order to avoid loss of the components that are subject of the investigations.

PHYSICOCHEMICAL PROPERTIESOF BEAVER WETLANDS WATER
IN THE KŁUDA VALLEY
Grażyna Szpikowska, Józef Szpikowski
Summary
Beavers settle entails various changes in the functioning of geoecosystems: hydrological (associated with the conditions of flow and drainage of water from the catchment and the conditions of retention), geomorphological, affecting the level of biodiversity and affecting the water quality. Research undertaken in the Kłuda catchment, a tributary of the upper Parsęta (Drawskie Lake), focused on knowledge of water chemistry within the beaver wetlands. The quality of these of waters compared with the chemistry of groundwater in the adjacent slope system and river water. It was changes in the oxygenation of groundwater and waters stagnant on the surface of beaver wetlands. Reducing conditions in the waters of beaver wetlands reduce the concentration of nitrate ions. The groundwater in the zones of beaver wetlands reduction of the concentration of sulphate ions and increase the concentration of ammonium ions and phosphate are observed. Beaver wetlands in the Kłuda catchment partially limit loads eutrophying components
