    Opis:
    The work shows the evaluation of physico-chemical parameters of water Resko lake, based on the European Union Water Framework Directive. Research was carried out in the years 2008-2009, in the period from April to October. With each of the three measuring stations on the tested water samples were taken two separate Lakes for chemical analysis. At the place of sampling were numbered pH. Trying to test water were taken by Polish Standards. Collected water samples were fixed in accordance with the recommendations in the Polish Standards. Other indicators for the quality of the waters have been tagged within 24 hours from the moment of download attempts. Have studied lake close to neutral pH - 7.63 to 7.79. All lakes in accordance with the classification of the European Union Water Framework Directive have been included in the first class. Studies have shown a diverse water quality in lakes in relation to tested indicators. By analyzing the average annual values can be noted that the pH of the water, the O2diss and the concentration of NO3? showed a relatively small variation in all investigated Lakes. The level of the General Suspension in Resko lake the peasant was on level II class. The concentration in the surface layer of Ptot. Lake is little differentiated, is at level II quality class according to the classification of the European Union Water Framework Directive. The concentration of total phosphorus is 0,22-0,29 mg?dm-3.

    Opis:
    We carried out a detailed study of the kinetics of oxidation of N'-ferrocenylmethyl-N'-phenylbenzohydrazide (FcX) to ferrocenium ion (FcX+) in aqueous and organic mediums. This study using cyclic (CV) and rotating disk electrode (RDE) voltammetry showed that the FcX/FcX+ redox couple is reversible. The N'-ferrocenylmethyl-N'-phenylbenzohydrazide and ferrocenium ion diffusion coefficients (D) were calculated from these results. In addition, the electron transfer rate constant and the exchange current density for the oxidation of ferrocene were determined. A comparison of the kinetic data obtained from the two electrochemical techniques appears to show that the data from the RDE experiments are more reliable because they are collected under strict mass transport control. Have studied lake close to neutral pH - 7.67 to 7.73. All lakes in accordance with the classification of the European Union Water Framework Directive have been included in the first class. The concentration in the surface layer of Ptot. Lake is little differentiated, is at level II quality class according to the classification of the European Union Water Framework Directive. Tested water lakes were changing the concentration of the PO43-diss - these concentrations correspond to water quality from III. The increase of the concentrations of phosphorus in the Lake may indicate a decrease in the amount of oxygen in the waters of the shallow and changes their status to release phosphorus compounds accumulated redox in sediment bottom. In the case of nitrogen-compounds nitrates and nitrites values for these indicators were at level I and II class in all the surveyed lakes in accordance with the classification of the European Union Water Framework Directive. Indicator, which indicates the high productivity of Lake is the biochemical oxygen demand (BOD5). The level of this indicator values on the studied Lake was on level III class. In the remaining Lake oxygen concentration was similar (continued in I class). Fauna of the Resko Lake bottom during summer stagnation was poor in terms of quality, which proves its considerable biological degradation. In terms of the concentration in the test macrozoobenthos Lake dominated, and Oligochaeta, Diptera larvae.

    Have studied lake close to neutral pH 7.70 to 7.74. All lakes in accordance with the classification of the European Union Water Framework Directive have been included in the first class. Studies have shown a diverse water quality in lakes in relation to tested indicators. By analyzing the average annual values can be noted that the pH of the water, the O2diss and the concentration of NH4+, NO2?, NO3?, PO43-diss showed a relatively small variation in all investigated Lakes. The level of the total suspended solids in Starzyc lake the peasant was on level II class. The concentration in the surface layer of Ptot.

In the case of nitrogen-compounds nitrates and nitrites values for these indicators were at level I and II class in all the surveyed lakes in accordance with the classification of the European Union Water Framework Directive. In 2008 attendance related macrofauna test bed showed that the most common they were mud-eating and larvae chironomids, oligochaeta (F = 100%), which consisted of Tischlera classification of the species is absolutely solid. Among larvae of Chironomidae the species is absolutely integral were Chironomus f. l. plumosus (F = 100%). However Chaoborus sp. belong to the accesoric species. Other designated species of fauna were accidental species of benthic (F) = 25%.
