Opis:: Honey is a sweet substance produced by bees, well appreciated in many places and its consumption has been increased either as raw material or as a food ingredient. Its use as food by the consumer, or even for exportation, implies safety inherent in its quality and processing control. Gamma radiation can be applied in food or ingredients for many objectives like pathogens microorganisms’ reduction, disinfestations, and sterilization. The aim of this work was to verify some physicochemical modifications, as well as rheological evaluation of honey submitted to irradiation at 10 kGy. The physicochemical parameters analyzed were: moisture, HMF, free acidity, pH, sugars and ash. The rheological behavior was measured at different temperatures. The results indicated that few changes occurred; the rheological behavior was not impaired and did not present any significant physicochemical alteration.

Opis:: The Chelopech epithermal arsenic bearing high-sulphidation, copper-gold deposit located in Bulgaria is often considered as the richest European gold deposit. Selected physicochemical parameters have been measured at key flotation streams inside the processing plant. Sampling campaign has followed with samples being submitted to chemical and mineral liberation analyses. A quantitative analysis has enabled to link copper flotation response to the type of copper bearing minerals and physiochemical parameters such as redox potential (Eh), dissolved oxygen (DO), EDTA extractable Cu and Fe. Data from the mineral liberation analysis (MLA) have highlighted an important process- relevant information explaining the variable floatability in different particle size ranges. A low chalcopyrite recovery can be linked to the non-sufficient amount of dissolved oxygen inside the copper selective flotation. Given the finely-disseminated copper bearing minerals, copper losses due to particle locking could be suggested as well.

Korzkiewka stream
Opis:: The aim of the paper was the identification and assessment of the area of anthropogenic impacts on water quality in the catchment of the Korzkiewka stream flowing through the areas of the Malopolska region. Analyses of physicochemical indices revealed that waters along the whole length of the stream qualified for below good status due to the exceeded EC and nitrate nitrogen concentrations. It was found that among 21 analyzed physicochemical indices, statistically significant differences occurred for 5: total dissolved solids, SO₄^2-., Mg²⁺, K⁺ and water pH. In the headwaters section values of four salinity indices were significantly higher in relation to the other part of the stream. Assessment of anthropogenic factors affecting the catchment water resources conducted on the basis of unitary and percent indices revealed that the dominant category shaping the physicochemical status of the Korzkiewka stream water is municipal economy. The intensity of the influence of the factors from this category was from medium to very high, while in case of sewage discharged through the sewage network, even to outlier intensity. Forestry and agriculture exerted medium pressure, whereas the factors from the industry category had hardly any influence on water in the stream.

Opis:: The aim of work was to characterise the physical and chemical properties of spray dried honey preparations and the changes in these properties during storage. Spray drying was performed at inlet air temperature 160 and 200°C, atomising disk speed 32 000 and 38 000 rpm, with the use of two types of carriers: dextrin and maltodextrin. The resulting powders had the desirable physical properties: low water content and activity, complete solubility and low cohesiveness. The powders produced with the use of dextrin had higher hygroscopicity and poorer solubility, they were also characterised by the highest water absorption during storage. Powders obtained with the use of reduced atomisation speed were the most stable in terms of water absorption and the changes of hygroscopicity during storage. Solubility of all powders was stable during storage.
Celem pracy było określenie właściwości ﬁzycznych i chemicznych preparatów miodowych suszonych rozpyłowo oraz zmiany tych właściwości w czasie przechowywania. Suszenie rozpyłowe przeprowadzono przy temperaturze powietrza wlotowego 160 do 200°C, szybkość obrotowa dysku rozpylającego wynosiła 32 000 i 38 000 obrotów na minutę, użyto dwóch rodzajów nośników: dekstrynę i maltodekstrynę. Otrzymane proszki miały pożądane właściwości ﬁzyczne: niską zawartość i aktywność wody, całkowitą rozpuszczalność i niską spójność. Proszki wytworzone z wykorzystaniem dekstryny miały wyższą higroskopijność i gorszą rozpuszczalność, charakteryzowały się najwyższą ilością wchłoniętej wody w czasie przechowywania. Proszki otrzymane z wykorzystaniem zmniejszonej szybkości obrotowej dysku rozpylającego były bardziej stabilne pod względem absorpcji wody i zmiany higroskopijności podczas przechowywania. Rozpuszczalność wszystkich proszków była stabilna w czasie przechowywania.

Opis:: The authors analyzed the physicochemical parameters and heavy metals characterizing the wells at three different sites (nearby villages) in the area of KEC (Kosovo Energetic Corporation). The KEC power plants are the only ones in Kosovo that use fossil-fueled energy (lignite) for the production of the electricity. This process may pollute the environment through the release of airborne aerosols (contaminated with metals), ash (a part of its content that leaches in the underground waters), etc. This pollutes air, surface water, groundwater and soil. In addition, the coal exploitation activity as raw material for power plants, excavating from mining basins, conveyor belt transport, separation before combustion and other processes involving the formation of dust sources and coal particles in the air also contribute to the pollution. Thus, it is of utmost importance to evaluate the water quality of the wells that are used as drinkable water sources by the people that live in this industrial area.

Opis:: Hydrochemical research was conducted in 2011 at three measurement-control points on the Sztoła river, a left-bank tributary to the Biała Przemsza river. Water temperature and pH, dissolved oxygen concentration, oxygen saturation and electrolytic conductivity were measured directly in the field. 11 selected physicochemical indices of the Sztoła surface water were assessed in the laboratory. The analysis of the research results revealed that the water of the Sztoła along the analyzed river reach was first class quality. The analysis of water usable qualities proved that at point 1 it can be used for water supply after high-performance physical and chemical treatment, whereas at other points after a typical physical and chemical treatment, due to high manganese concentrations. Water does not meet the requirements of natural habitat for the Salmonoid fish only at point 1 because of exceeded standard values for nitrites. The Cyprinid fish have the proper habitat conditions along the examined river reach. Among 15 analysed physiochemical indices of water, 7 were statistically higher in the lower course, but they did not affect worsening of the Sztoła river water quality. Greater water pollution in the central and lower river reach is caused by the anthropogenic pressure connected mainly with the operations of extraction industry in the catchment.

Opis:: The aim of this study has been to determine the response of cyanobacteria to the lake protection and restoration measures implemented in the littoral zone of an urban lake called Jeziorak Mały. The first investigations were conducted in 1996 and were resumed in 1997-2003, 2005 and 2013, following the installation of a separator and the creation of stone accumulation sites. Long-term changes in phytoplankton cyanobacterial proportions, abundance and biomass were analyzed in relation to environmental conditions at the sites in the littoral zone (S – separator pipes, K – sites with stones and R – sites with macrophytes). Relationships between cyanobacteria and water chemistry variables were analyzed by calculating the Spearman’s rank correlation coefficient, and then with canonical correspondence analysis (RDA). The results provided evidence that water temperature, total nitrogen and iron concentration (S, R), but also PO43- in spring (S,K) were the principal factors affecting cyanobacterial development. There was a significant decrease in the share, abundance and biomass of cyanobacteria coinciding with a decrease in conductivity and PO43- following the onset of lake restoration efforts. Changes in dominant species from the ones typical in hypertrophic lakes to those typically found in eutrophic lakes took place during the research. The modifications indicated a strong initial response of cynaobacteria to the restoration measures, but the situation stabilized in 2013, when cyanobacteria returned to their previous average levels. This suggests that the introduction of lake restortation measures contributed to the lake’s improved water quality and they should be retained for efficient lake management in the future.
