Opis:
The purpose of the paper was to determine the impact of the most popular form of recreation and tourism (i.e. walking) on the environment in selected forests that were made available by the means of educational trails. The research was carried out in south−eastern Poland, in the forest reserves Bór (RB) and Polanki (RP) as well as in the economic forests of the Kołaczyce (NK) and Brzozów (NB) forest districts. A 1−km−long transect was established on both sides along each educational trail with control points determined every 10 m. In total 200 points were distinguished and data on the degree of soil damage was collected at research plots with an area of 1 m2 each. Based on these 200 plots, damage of young trees and soil were measured. The studies indicate that the damage to the soil and trees in the immediate vicinity of the routes available for recreation and tourism are very large. In all objects, 53−99% of the soil surface and 28−56% of trees were damaged. Slightly damaged soil earned the highest fraction on all studied trails (for NK it was 62%, RB – 49%, RP – 35.5% and NB – 26.5%). The most severe soil damage (packed soil) was recorded in as many as 37% of the measurement points in RB, 9.5% in RP and NB and 7% in NK. The most common form of damage to the trees was bark rub without damaging the pulp or partial damage to the needles or leaves. In case of NK, such damage was observed in 41% of trees, while 30.4% of RB, NB in 20.9% and RP in 13.9%. Trees ranked as the 2 most severe degrees of damage accounted for as much as 9.2% in NK, while 7.2% of RP, 6.4% in RB and 5.6% in NB. The damage level of the examined components of the forest environment determined in the study as a result of tourist and recreational use should be considered as high.

Opis:
The western part of Podhale region is drained by the Czarny Dunajec and the Biały Dunajec rivers, flowing from the Tatra Mts., and streams originating in the region (Cichy Stream, Bystry Stream, Czerwony Stream, Wielki Rogoźnik). River banks are cut in the Podhale Flysch or in the alluvium of these rivers overlain with loam deposits of varied origin. This paper investigates the combined effect of weathering, frost processes and mass movements on the banks of the Czarny Dunajec River and its tributaries typified by different substrate material. Bank retreat due to frost processes was measured during multigelation periods using erosion pins. Grain size distribution and cohesion of the substrate were also determined for alluvial and loam deposits. On flysch cutbanks, we determined joint spacing and the density and direction of fractures, and other structural and textural characteristics of the rocks. The results indicate that the rate of bank retreat decreases from the banks cut in sandy loam deposits, through alluvial loam banks (with high clay content), the banks composed of poorly cemented gravels and shaly flysch, to the banks cut in sandstones and highly cemented Neogene gravels. Bank retreat due to frost processes and mass-wasting was more efficient in the cold half-year.

Opis:
This study was aimed to conduct an analysis of the efficiency of pollutant elimination in the Dobra treatment plant, which operates based on the SBR reactor. The object purifies domestic sewage and pre-treated industrial sewage from a slaughterhouse within the Dobra municipality. The source material for the analysis comprised the values of pollution indicators: BOD5 , CODCr, total suspended solids (TTS) in raw sewage (19 samples) and treated sewage (34 samples). The results of chemical analyses were obtained in the period 2007-2014. The results were compared with the limit values imposed by the Regulation (2014). The coefficient of reliability of the treatment plant was also calculated in this study. The average efficiency of pollutant elimination in the treatment plant was: BOD5 - 98.6%, CODCr - 94.9%, total suspended solids - 97.6%. These results demonstrate that the studied facility operates flawlessly and the treatment efficiency is high. On the other hand, the reliability coefficient values indicate that the operation of this object is unstable.

Opis:
Cadmium-induced oxidative burst is partially mediated by NADPH oxidase. The aim of the present research was to evaluate the role of NADPH oxidase in soybeans’ response to short-term cadmium stress. The application of an NADPH oxidase inhibitor, diphenyleneiodonium chloride (DPI), affected expression of two Cd-inducible genes, encoding DOF1 and MYBZ2 transcription factors. This effect was observed after 3 h of treatment. Interestingly, Cd-dependent increases in NADPH oxidase activity occurred only after a period of time ranging from 6 and 24 h of stress. Stimulation of the enzyme correlated in time with a significant accumulation of reactive oxygen species (ROS). Further analysis revealed that pharmacological inhibition of NADPH oxidase activity during 24 h of Cd stress does not affect Cd uptake, seedling growth, or the level of lipid peroxidation. The role of NADPH oxidase in the response of soybean seedlings to short-term Cd exposure is discussed.
