Purpose. Environmental assessment of the quality of surface water of small and medium rivers of the Poltava region, in particular: medium rivers – Psel, Vorskla, Merla and five small rivers –Govtva, Grun, Kolomak, Poluzorie, Tashan. Methods. Field, atomic absorption spectrophotometry, cluster analysis. Results. In accordance with the quality standard for surface water of cultural and household purposes, all indicators for medium-sized rivers are within the normal range. There was an excess of zinc in the waters of small rivers - Grun, Tashyas and Poluzorie. The low content of soluble oxygen does not meet the norm. When comparing values ​​with the norm of quality of water for reservoirs of fishery management, excess BOD-5 for the Vorskla and Psel rivers is defined; the content of ammonia and nitrites significantly exceeded the normative value for the river Vorskla, Psel, Merla. The excess of surfactants for medium rivers is determined. The river Vorskla is mostly polluted with cupper; the Psel river – with zinc and iron, in water from the Gotvva, Tashan, Poluzorie and Grun rivers we have identified exceeding BOD-5. Regarding the water-soluble nitrogen compounds, only the nitrogen content corresponds to the normative value. The greatest pollution with ammonia is observed for the Govtva and Kolomak rivers. Excess of MAC on the content of nitrites was identified for the Kolomak river. As a result of the cluster analysis of the river, the degree and nature of pollution of surface water are grouped into three main groups: the first is the Kolomak river, the second one is the Merla, Psel, Grun, Vorskla rivers, the third one is the Tashan, Poluzorie and Govtva rivers. In the future, the results can serve as a tool for regulation, monitoring and solution of pollution problems. Conclusions. Small rivers of Poltava region are under considerable anthropogenic impact, their ecological status is estimated as ecological regression. Therefore, priority attention should be paid to improving the ecological status of small rivers in the Poltava region and implementation of the proposed nature conservation measures.

Sensory Data

This study demonstrated that both chymosin and salt-in-moisture (SM) were important factors for proteolysis in the manufacture of ultrafiltrated white-salted cheese, with significant effects on water-soluble nitrogen and nitrogen soluble in trichloroacetic acid. In contrast, the levels of free amino acids were not significantly affected by chymosin and salt treatments. The cheeses made using high levels of chymosin with low SM had lower levels of residual αs1- and β-casein at the end of ripening. On texture profile analysis, the hardness and fracturability of the cheeses significantly increased with SM and decreased during ripening. Increases in chymosin significantly contributed to the overall weakening of the structure throughout ripening. Bitter flavour was detected after 12 weeks in the cheese made with the higher chymosin level and lower SM, which could be the result of accumulation of γ-casein fractions. The sensory data indicated that the hedonic responses for low chymosin with low SM cheeses were good and acceptable in flavour, which may be due to the moderate levels of proteolysis products.

Bromelain is one of the protease that can be produced from all of parts of the pineapple plants (Ananas comosus). It has potential to improve quality of local Indonesian food such as tempeh gembus, virgin coconut oil (VCO), and dumbo catfish based fish sauce (DCBFS). Tempeh gembus is a traditional food that has unique characteristics especially in its taste because it contains amino acids. VCO attracts consumers because of its health aspect. Its raw materials are available in Indonesia. DCBS  is a product of fermented fish with salt that has a distinctive taste and is produced in Indonesia. This study aimed to analyze the effect of bromelain on local Indonesian food and its applications. The result showed that the use of bromelain in local Indonesian food could improve the quality and nutritional value of local food. Bromelain can be used in local food like tempeh gembus, virgin coconut oil, and fish sauce from dumbo catfish. The use of bromelain in tempeh gembus could  increase both of the water-soluble nitrogen level and the pH value. However, the addition of bromelain in the production of virgin coconut oil and fish sauce from dumbo catfish could increase the yield of theirs. .

The quality of surface waters of small rivers of the Ukrainian regions of right-bank Polissia, belonging to the basin of the river Pripyat, was estimated. The study was conducted via systematic observations based on the ecological classification of surface water quality of land and estuaries of Ukraine, which includes a set of hydrophysical, hydrochemical, hydrobiological and other indicators, which were grouped into three blocks of indicators: salt composition of water; tropho-saprobiological (ecologicalsanitary) block; specific substances of toxic action. The integrated (ecological) index was determined, by which the class and category of surface water quality were established. The results of observations on the quality of surface waters of the rivers of the Ukrainian regions of right-bank Polissia indicate their satisfactory condition. Surface waters, on average, correspond to the II class of water quality, and the worst - to the III class. Water protection measures have been proposed to improve the ecological condition of small river basins in specified region.

The influence of three different ventilation regimens on air pollution in sheep houses and on the quality of ewe milk and of Canestrato Pugliese cheese was investigated during the summer season. The experimental treatments were low ventilation regimen (VR=35 m3/h per ewe) split in 30-min ventilation cycles (LOV-30); moderate ventilation regimen (VR=70 m3/h per ewe) split in 30-min ventilation cycles (MOV-30); moderate ventilation regimen (VR=70 m3/h per ewe) split in 60-min ventilation cycles (MOV-60). The LOV-30 milk had higher microbial load and bulk milk somatic cell count (BMSCC) and resulted in a weaker casein matrix in the curd compared with the MOV-30 and MOV-60 treatments. At 45 d of ripening, the LOV-30 cheeses had a lower casein content and higher non-casein nitrogen (NCN) and water-soluble nitrogen (WSN) contents than the MOV-30 and MOV-60 cheeses. Urea-polyacrylamide gel electrophoresis (urea-PAGE) of the pH 4·6-soluble N extract showed that the MOV-60 cheeses had fewer bands derived from casein (CN) hydrolysis than the LOV-30 or MOV-30 cheeses, despite its having exhibited the highest plasmin (PL) activity levels. Our results suggest that the ventilation regimen is critical in dairy sheep housing for optimizing the hygienic quality of ewe milk and the proteolytic processes occurring in Canestrato Pugliese cheese during ripening.

AbstractVarious antimicrobial solutions have been tested as additives for raw milk traditional cheeses, among whichNigella sativacold pressed seed oil (NSSO) is recognized for its positive effect on the microbial quality of such products. The overall effect on the quality of enriched cheeses during ripening is still under extensive investigation. Three batches of traditional raw milk brined cheese were included in the current experiment: control cheese withoutNigella sativaseed oil (NSSO) and cheese samples enriched with 0.2 and 1% w/w NSSO. Experimental cheese samples were analyzed in duplicates for total nitrogen content (TN), at 0, 14, 28 and 42 days of ripening, while single determinations of total nitrogen (WSN) and free amino acids (FAA) were performed at 14, 28 and 42 ripening days. The TN content revealed similar values for control cheeses and NSSO cheeses, and no significant differences were noticed within the three treatment groups (p >.05) throughout ripening. WSN values followed a significant rising shift in all cheeses during ripening, yet computing data obtained for the three considered treatments, despite an obvious higher WSN content of NSSO enriched cheeses, no statistical significance could be associated to this difference. The FAA composition of the experimental cheeses, varied quantitatively, by increasing with ripening time, but no qualitative variation was noticed during the follow-up period. The FAA composition of the did not vary significantly within treatments.

Purpose – perform ecological assessment of the surface waters of the Rostavytsia river within the Zhytomyr region. Method. Environmental assessment of the surface water of the Rostavytsia river was carried out using the system of classification of standards for the assessment of surface water quality of Ukraine. On the basis of common environmental criteria, the methodology makes it possible to compare the quality of water at different sites of water bodies, in water bodies of different regions. The calculation of the ecological assessment of water quality was carried out within three blocks: block of salt composition (І1), block of trophic-saprobiological (ecological-sanitary) indicators (І2) and block of indicators of content of specific substances of toxic action (І3). The results are presented in the form of a combined environmental assessment based on the final conclusions of the three blocks and based on the calculation of the integrated environmental index (IE). Results. Omprehensive studies on changing the water quality of the Rostavytsia river were conducted within the Zhytomyr region during 2016-2017. The water quality of the river according to the final values of the integral indicators of water quality of the three blocks varies within the II and III quality classes. The total environmental indices (IE) for the mean and worst indices are 3,2 and 3,3 respectively. In general, the water quality along the main channel of the Rostavytsia river within the Zhytomyr region corresponds to the second class, 3 categories, 3 subcategories according to the average quality indicators and 3(4) subcategories by worst performance. The total values of the integral surface water quality indicators of the Rostavytsia river indicate their contamination by trophic-saprobiological components. Scientific novelty. For the first time, on the basis of analytical studies and stock materials, an ecological assessment of the surface waters of the Rostavytsia river within the Zhytomyr region was carried out by three blocks of indicators: salt composition, trophic-saprobiological indicators and specific toxic substances. The integral ecological index is determined. The trends of pollutants accumulation in the surface waters of the Rostavytsia river have been established. Practical significance. The conducted researches allowed to analyze and evaluate the ecological status of the surface waters of the Rostavytsia river within the Zhytomyr region, which will allow to establish ecological standards of water quality and on this basis to determine the main directions for improvement of water resources and to substantiate the system of recommendations aimed at improving the ecological status of the studied basin.

The characteristics of leachate and its probable risks on surface and groundwater pollution were investigated following the analysis of some chemical parameters of the leachate generated in the Matuail landfill site, Dhaka, Bangladesh. The laboratory test results on untreated grab leachate samples show high concentration of TDS (734 ppm), COD (1631 ppm), NH4 +-N (1253 ppm), HCO3 - (27962 ppm) and certain heavy metals such as Ni (1.05 ppm) and Cr (0.74 ppm) and have very high potential for contaminating ground and surface water. Biological treatment through aeration and sedimentation improves the quality of leachate significantly. However, parameters such as COD (1437 ppm) are found to be still high even after treatment. The surface water samples around the landfill site appear to be contaminated, most probably, through the overflow of leachate. Groundwater parameters, however, satisfy drinking water quality standard except, the concentration of NH4 +-N (maximum 74.2 ppm) and K (maximum 25 ppm).
