Opis:
The Dojlidy Ponds, which include Dojlidy water dam, are located within Bialystok city limits in Podlasie area, Poland. The reservoir with a water surface of 34 ha and average depth of 1.75 m was constructed in 1962 as a result of Biala River damming. The researches were conducted in July, October and December 2014 as well as in March 2015. Each time five test samples were collected from spots located along the reservoir. Water samples were tested for the presence of ammonia nitrogen, nitrite nitrogen, organic nitrogen, phosphates and organic phosphorus. The values of nutrient indicators exhibited high variability during the study period. The highest concentration of nitrite and nitrate nitrogen were observed in July, while the lowest in October – nitrite nitrogen, and in December – nitrate nitrogen. Different situation was observed after the analysis of phosphorus forms – the highest concentrations of organic phosphorus and phosphates were observed in December and the lowest in July. Relatively high concentrations of nitrogen and phosphorus forms identified in water samples were most likely caused by tributaries, due to the pollution from the reservoir catchment. Technical parameters of the object and location of the reservoir have undoubtedly an impact on the tested parameters contents.

Opis:
Celem badań była ocena jakości wody w dwóch małych zbiornikach retencyjnych oraz oszacowanie ilości zatrzymanych zanieczyszczeń przez oba zbiorniki. Badania zmian jakości wody oraz analizę czynników ją determinujących prowadzono na dwóch zbiornikach małej retencji położonych w województwie podlaskim: Ciechanowiec, zlokalizowanym na rzece Nurzec oraz Bobra Wielka umiejscowionym na rzece Biebrza. Podstawowe parametry fizyko-chemiczne wód zbiorników oraz wód je zasilających w większości nie wykraczają poza wartości dopuszczalne dla klas I-II. Jedynie wysokie stężenia fosforanów, dopływające bezpośrednio do rzek zasilających zbiorniki, wielokrotnie przekraczają ilości dopuszczalne i mogą być potencjalnym źródłem zanieczyszczenia badanych akwenów. Coroczne zwiększanie się ilości dopływających zanieczyszczeń wskazuje na powolny wzrost poziomu degradacji zalewów. Badane zbiorniki należy poddać zabiegom rekultywacyjnym ponieważ nie spełniają roli w ograniczaniu zanieczyszczeń dopływających ze zlewni.
The purpose of the research was to evaluate the water quality in two small retention reservoirs, as well as assessing the amount of quality indicators retained by both of them. Water quality studies and the analysis of factors determining it were conducted on two small retention reservoirs situated in the Podlaskie Voivodeship: Ciechanowiec, located on the Nurzec River and Bobra Wielka situated on the Biebrza River. The basic physicochemical parameters of the water reservoirs and of the water supplying them mostly do not exceed the limits for classes I-II. High concentration of phosphates, which flow directly into the river supplying the reservoirs, exceed the permissible amounts by many times and may be a potential source of contamination of the examined water reservoirs. The yearly increase of the considered contaminants indicates a slow degradation of reservoirs. The reservoirs should be subjected to reclamation as they are inefficient in limiting pollution from the catchment area.

Opis:
The study was carried out using water samples from two small retention reservoirs located in the communes: Czarna Białostocka and Turośń Kościelna in Podlaskie Voivodeship. The main tasks of both reservoirs are to improve the water balance by means of regulating the levels and water outflow. Three characteristic measurement and control points were selected on both reservoirs in accordance to the water flow in the longitudinal section. The first and third points were located near the inflow and outflow of water, while the second in the middle of the reservoirs. Samples of water for the study were collected from the surface layer of the shore zone of the reservoirs once a month from March 2015 to February 2017 (water from two hydrological years was analyzed). Water samples were subject to determination of total phosphorus, total nitrogen, and chlorophyll “a” concentrations, as well as turbidity. Contamination of the water reservoirs with biogenic compounds is a common problem and at the same time difficult to eliminate due to the scattered nature of external sources of pollution, especially in the case of agricultural catchments, as well as the inflow of untreated sewage from areas directly adjacent to the reservoirs. Based on achieved results, high values of TSI (TN), TSI (TP), TSI (Chl), and overall TSI, clearly indicate the progressive degradation of water quality in analyzed reservoirs. Appearing water blooms due to the mass development of phytoplankton adversely affect the quality of water in the reservoirs and biochemical processes occurring both in water and bottom sediments, are conditioned by progressive eutrophication.

Opis:
Introduction: Proton-pump inhibitors (PPIs) are a class of drugs which decrease gastric acid production, their overuse is becoming increasingly common. Purpose: The aim of this study was to evaluate medical indications for PPIs in a cohort of prevalent hemodialysis (HD) patients and their awareness about the medical effects of these drugs. Materials and methods: The study was performed in 78 HD patients enrolled in a chronic dialysis program in a single academic dialysis unit. The study was based on medical history obtained from the patients (survey about drugs they take with intention of revealing PPIs, indications for the treatment, their awareness of the mechanism of action of these drugs).Results: 46 patients (59%) took or have been taking PPIs. Almost half (49%; n=22) had no clear medical indications for the drugs. Prescription of PPIs without medical indications was more common among nephrologists (27%), when compared with gastroenterologists (5%; p<0.05). Only 29% (n=13) of patients taking PPIs were aware of the mechanism of action of the drugs. Conclusions: Results of this study reveal the problem of PPI overuse among HD patients. Gastroenterologists usually prescribed PPIs according to medical indications. Lack of patients’ knowledge about the indications for PPI therapy is overwhelming.

Opis:
The study aimed at comparing changes in the trophic status of waters in two small retention reservoirs “Otapy-Kiersnówek” and “Jasionówka”, located in the Podlasie region, which have a similar way of management and the similarity of catchments, using the TSI trophy indicators. The obtained results show that total phosphorus is the limiting factor in both reservoirs. Analyzing the average annual value of TSI in the tested waters, it was found that both reservoirs can be classified as hypertrophic. Trophic state of the tested waters is strictly dependent on the processes taking place in their vicinity. The reservoirs revealed a clear effect of a surface runoff on water quality. Factors that favor the poor quality of water in both reservoirs are unfavorable morphometric conditions of reservoirs due to their small depth, which allows continuous mixing and strong heating of water in spring and summer. Additional causes can include an open space around the reservoirs and the lack of high vegetation that would shield the edges against the wind, which facilitates often mixing of waters to the bottom and resuspension of bottom sediments, which in turn increases the concentration of phosphorus in water.

Opis:
Celem badań była ocena jakości wód dopływających do zbiorników małej retencji ze względu na stężenie w nich fosforu ogólnego i fosforanów. Do badań wybrano trzy zbiorniki małej retencji położone na terenie gmin: Brańsk, Dubicze Cerkiewne i Kleszczele w województwie podlaskim. Doboru obiektów badawczych dokonano z uwagi na podobieństwo rodzaju zagospodarowania zlewni cieku dopływającego, sposobów wykorzystania retencjonowanej wody oraz niewielką powierzchnię zbiorników. Dopływający do zbiornika ciek wnosi wraz z wodą substancje biogenne, które wpływają na jakość jego wód w sposób bezpośredni, powodując wysokie stężenia w wodzie, albo pośredni polegający na inicjowaniu lub przyspieszaniu procesów degradacji zbiornika i utratę jego walorów użytkowych. Stwierdzono, że stężenia fosforu ogólnego jedynie w przypadku 20,8% próbek wody pobieranych z rzeki Nurzec, zasilającej zbiornik Otapy-Kiersnówek, około 25% próbek wody rzeki Orlanki, zasilającej zbiornik Bachmaty i 17% próbek pobieranych z cieku zasilającego zbiornik Repczyce odpowiadały wartościom określonym dla drugiej klasy w obowiązującym Rozporządzeniu Ministra Środowiska. Spowodowane jest to długotrwałym nawożeniem nawozami naturalnymi, co w konsekwencji doprowadziło do przesycenia gleb i przedostawania się związków fosforu do wód rzecznych na terenach użytkowanych rolniczo. Zwłaszcza w okresach wczesnowiosennych rosnąca temperatura wraz z opadami deszczu powodowała rozmarzanie gleby co skutkowało rosnącymi stężeniami zanieczyszczeń wnoszonymi wraz ze spłukiwanymi cząsteczkami gleby podczas spływu powierzchniowego i podpowierzchniowego. Obliczone wartości TSI(TP) w zbiorniku Otapy-Kiersnówek wyniosły 112,4 w 2012 roku hydrologicznym a 112,7 w 2013 r., w zbiorniku Bachmaty 73,04–75,71 i w zbiorniku Repczyce 101,07–102,12, co pozwoliło je zakwalifikować jako hipertroficzne.
The aim of study was to evaluate the quality of water flowing into small retention reservoirs in terms of the concentration of total phosphorus and phosphates. The study involved three small retention reservoirs located in the municipalities of: Bransk, Dubicze Cerkiewne and Kleszczele in Podlasie region. Selection of the research facilities was made due to the similarity in the soil management type within catchment of the flowing watercourse, retained water utilization ways, and a small surface of reservoirs. Watercourse reaching the reservoir provides biogens along with water, which directly affect the water quality resulting in high concentrations in water, either indirectly by initiating or accelerating the process of degradation of the reservoir and the loss of its usability. We found that total phosphorus only of 20.8% of water samples from Nurzec river feeding the Otapy-Kiersnówek reservoir, about 25% of water samples of Orlanka river feeding Bachmaty reservoir, and 17% of samples taken from the watercourse supplying Repczyce reservoir, corresponded to values specified for the second class in the current Regulation of the Minister of the Environment. It can be assumed that this situation is caused by a long-term fertilization using manure, which in consequence led to the oversaturation of soils and phosphorus compounds penetration into the river waters in areas used for agricultural purposes. Especially in the early spring periods, rising temperature together with rainfall caused soil thawing resulting in increasing concentrations of contaminants carried along with the washed soil particles during the surface and subsurface runoff. Values of TSI(TP) calculated for Otapy- Kiersnówek reservoir amounted to 112.4 in hydrological year 2012 and to 112.7 in 2013, for Bachmaty reservoir 73.04–75.71, and for Repczyce reservoir to 101.07–102.12, which allowed for qualifying them as hypertrophic.

Opis:
The study aimed at determining the changes in the trophic status of the processes associated with the risk of eutrophication in small retention reservoir in Korycin, characterized by agricultural performance of direct and indirect catchment. The study was conducted using the surface water samples that were collected systematically every month over four hydrological years (2008 to 2014) from three research points. Mean annual concentration of total phosphorus varied from 0.641 mg P/dm3 during research conducted in 2007/2008 to 0.874 mg P/dm3 in 2013/2014 showing an increasing trend from year to year. Taking into account the calculated average values, an upward trend can be seen along with particular years of the study from the annual average value of 1.44 mg N/dm3 determined in the first year to the value of 2.66 mg N/dm3 recorded in the last year of the study. It was observed during the study that in non-flowing parts of Korycin reservoir, plankton developed more abundantly than in the central fragments, where the flow of water is more intensive. A mild growth of phytoplankton in the waters of Korycin reservoir is provided by relatively low concentrations of chlorophyll “a” found during all research periods. Concentrations of chlorophyll “a” in waters of the reservoir were within the range of 4.08 to 5.21 g/dm3. At a Schindler coefficient > 2, this value, based on the Decree of the Minister of the Environment of 2011, should not exceed 7 and therefore waters of the Korycin reservoir during the research can be classified as the first class. Values of the general trophic level (Trophic State Index) during the first three years of the study ranged from 67.15 to 68.65, which enabled to count waters of the reservoir in Korycin to eutrophic ones. In the last year of the analyzes, this coefficient increased to a value of 72.43, classifying its waters as hypertrophic. The largest share in such a situation was expressed by TSI (TP), which ranged from 97.34 to 101.82, always classifying the waters to hypertrophic ones. In contrast, the indicator TSI (TN) ranged from 59.71 to 68.57 and it classified the reservoir waters to eutrophic, while TSI (Chl) to mesotrophic.

Opis:
Studies upon the trophic status were carried out using water samples from a small retention reservoir Topiło located in a particularly valuable natural forests of Puszcza Białowieska. In order to assess the degree of Topiło reservoir contamination, three measurement and control points were selected for testing, which were situated near the inflow (point No. 1) and outflow (point No. 3) of river Perebel, as well as in the middle part of the reservoir (point No. 2). The selection and placement of measurement and control points on the reservoir was dictated by the ability to capture changes in the study object. Tests of water samples collected from the surface layer of the coastal zone, were carried out once a month during the period from April 2007 to March 2014. The following determinations in collected water samples were performed: total nitrogen, total phosphorus, chlorophyll “a”, and turbidity. The trophic level of Topiło reservoir was also assessed according to the concentration criteria and based on the trophic status indices (TSI) calculated after Carlson’s as well as Kratzer and Brezonik’s. Given the annual average value of overall trophic level (Trophic Sta-tus Index), the dominant role of the TSI (TP) during all years of research attracts some attention. The TSI index values ranged within 78.3–80.26, which allowed to classify the water of Topiło reservoir as hypertrophic. The research indicates an advanced and constantly progressive degradation of water quality in Topiło reservoir. Values of TSI (Chl) were in the range of 49.2–77.35 and therefore water status in winter can be defined as eutrophic indicating the hypertrophy in remaining periods under study. Additional investments planned for advance reclamation treatments should be necessarily taken into consideration at the stage of planning and design of new small water retention reservoirs. Topiło reservoir requires modernization and reclamation, it is also necessary to clean it up, especially the bottom pond, out of the stocked wood residues, as well as to remove the excess of sludge.

It should be taken into account, while creating programs for small water retention, that positive results may be obtained only in the case of clear water retention. During construction of small water reservoirs, cost effectiveness of maintenance as well as quality of stream water inlet should be taken into account. The atricle presents conditions of water retention in small reservoirs in the Podlaskie Voivodeship, forms of financing andd their dependance of the type of investment. Soil quality and the use of land for agricultural purposes have an effect on the quality of water in the reservoir basin. This generates a cost increase brought by a need to reclaim the existing reservoirs.

Opis:
When considering the issue of the functioning of small water reservoirs, the attempt to assess changes in trophy of small retention reservoir located in Wasilkow, Podlasie, before and after remediation, was carried out. Water samples tests were carried out once a month from April 2007 to March 2008, from April 2009 to March 2010 (before remediation), and from April 2013 to March 2014 (after removal of silt). Prior to works related to the reservoir remediation, a gradual increase in the number of tested contaminants and disturbances in the seasonal occurrence of nitrogen and phosphorus compounds were observed. Advanced eutrophic processes in Wasilków reservoir occur probably due to the supply of large amounts of humic and biogenic substances from the catchment, because a significant percentage of its area is covered by forests and agricultural lands. The development of the trophic status of the reservoir is largely influenced by the amount of phosphorus and total nitrogen supplied to the reservoir; the least affected by chlorophyll “a”. Comparing the analyses performed in 2007/2008 and 2009/2010, a slight, but growing trend of average trophic levels of water in the basin Wasilków was found. Studies conducted in 2013/2014 revealed a significant decrease in the concentrations of all analyzed pollutants, and hence lower TSI values. It can be concluded that the reclamation associated with the removal of sediments brought the expected results.

When analyzing the symptoms of eutrophication and water quality in a small retention reservoir Bachmaty, an attempt to assess changes in its trophic condition before and after modernization, was undertaken. The study upon changes in water trophic level was carried out on a small retention reservoir Bachmaty located in Podlasie region on the Orlanka river in the municipality of Dubicze Cerkiewne. Tests of water samples collected from the surface layer of the coastal zone were performed once a month, and the time of the research was divided into two periods. The first period was conducted since April 2007 to March 2008 and since April 2009 to March 2010. The second research period included the time immediately after the reservoir reclamation, which ended in May 2011. The study was conducted since May 2011 to March 2012 and since April 2013 to March 2014. The trophic level of Bachmaty reservoir was also assessed according to the concentration criteria and based on the trophic status indices (TSI) calculated after Carlson’s as well as Kratzer and Brezonik’s. Reclamation of the reservoir, which consisted mainly in removing the sediments, caused a reduction in all TSI values. Analysing the overall trophic level index, i.e. the average of TSI (TP), TSI (TN), and TSI (Chl), water of the Bachmaty reservoir may be classified as eutrophic in individual years of the research, although a gradual decline in the TSI value could be observed directly after the reservoir modernizing. After testing it was found that the formation of the trophic level of Bachmaty reservoir was largely affected by the amount of total phosphorus supplied to the water. Water quality in the reservoirs, and also the content of phosphorus compounds is largely determined by external supply.

Opis:
The necessity and purposefulness of the investments related to water retention are justified mostly due to the preservation of the environment equilibrium as well as due to its farming, anti-flood, landscape and recreation aspects. Reasonable water management where various forms of retention are used gives large chances for the mitigation of the effects of unfavorable phenomena related to its insufficient amount. The creation of plans regarding the formation of reservoirs accumulating water is not necessarily synonymous with their realization. The reason of problems connected with the implementation of plans regarding the formation of new reservoirs lies mainly in financial measures and in problems with obtaining them. Water deficit in Poland is the reason for which the principles of its national usage need to be complied with. Realization of plans at both Voivodeship and municipality level that are focused on small retention will contribute to considerable increase in the retention capacity and will enable considerable increase in available resources in hydrographic catchments of both the characterized area and the entire country. The paper presents the characteristics of the present state and assumes the perspective development of small water retention in the Podlaskie Voivodeship using the example of the Podlaskie Voivodeship.

Celem pracy było określenie źródeł zanieczyszczeń wód powierzchniowych i wybranych metod ich usuwania. Wody powierzchniowe zanieczyszczane są poprzez substancje migrujące z gleb oraz poprzez spływ powierzchniowy i podpowierzchniowy. Źródłami antropogenicznymi są melioracje komunikacja, rolnictwo i inne. Jedną z metod oczyszczania wód z jonów amonowych jest stosowanie metody wymiany jonowej z użyciem zwietrzeliny bazaltowej. Natomiast związki ropopochodne skutecznie mogą być usuwane metodą ultrafiltracji.
The aim of this study was to identify sources of pollution of surface water and some pollutant removal methods. Surface waters are contaminated by substances migrating from the soil and by surface flow and subsurface flow. There are other sources such as transport, land melioration, etc. One of the method of ammonium ion removal from the water is ion-exchange method using basaltic rock-mantłe. However oil-related compounds can be effectively removed by ultrafiltration.

Opis:
Jednym z podstawowych elementów infrastruktury związanej z właściwą regulacją stosunków wodnych są zbiorniki małej retencji. Większość z nich budowana jest jako obiekty wielofunkcyjne łączące szereg zadań - od zapewnienia niezbędnej ilości wody na potrzeby gospodarcze i hodowlę ryb, przez ochronę przeciwpowodziową, do wzrostu atrakcyjności przylegających terenów. Na Podlasiu zbiorniki małej retencji wykonuje się jako podpiętrzenia cieków wodnych, przy czym obszar spiętrzenia obejmuje jak największą część naturalnego terenu zalewowego cieku.
Accumulation of water in low-retention reservoirs is an important element for water conditions especially in countries with small water resources. The study included three low-retention reservoirs in Korycin, Otapy-Kiersnówek and Jasionówka (typically agricultural catchment) localized fully in Podlasie region. This article applies to results of physical-chemical researches with particular regard to biogenic compounds. Water quality surveys took place during the period of time from November 2011 to October 2012. The analysis of achieved results revealed that organic nitrogen was dominating form among nitrogen compounds in water from all reservoirs. During the research it is found that storage reservoirs characterized by a quite small area and storage cubic content are much more exposed on eutrophication than larger reservoirs. Agricultural use of the area and quality of the soils in drainage area affect on deterioration of the trophic state of small retention reservoirs.

Opis:
Woda jako ożywiony składnik środowiska ulega ciągłym zmianom ilościowym i jakościowym. Wraz ze zmianami objętości ulegają modyfikacji fizyczne, chemiczne i biologiczne właściwości wód, zwłaszcza powierzchniowych, w tym małych zbiorników wodnych. Zmiany ilościowe wód formowane są głównie dzięki zjawiskom hydrometeorologicznymi, a jakość wód na skutek nasilenia działań antropogenicznych w zlewni zbiornika. Zbiorniki retencyjne najczęściej usytuowane są w obniżeniach terenu, dlatego podlegają silnym wpływom obszarów przyległych, przede wszystkim poprzez dopływy zanieczyszczeń ze zlewni, w tym także związki pochodzące z nawozów organicznych i mineralnych, środków ochrony roślin i innych.
The aim of the study work was evaluation of seasonal changes of trophic state in retention reservoirs. The researches were done based on samples of water from two low-retention reservoirs: “Michałowo” and“Narewka”, located in Podlasie in Bialystok district. The choice of those two reservoirs was made by taking into the consideration following aspects: the way of development and the similarity of catchment area as well as the date of giving them to the public use. In the researches there were used available in literature Trophic State Indexes, based on made measurement of the concentration of chlorophyll, phosphorus and nitrogen. On the trophic state of Michałowo reservoir the biggest influence had nitrogen and phosphorus concentration, classifying this reservoir as eutrophic in spring and autumn, and as mesotrophic in summer and winter. On the trophic state of Narewka reservoir the biggest influence had phosphorus concentration classifying this lagoon as hypertrophic independently on the season of the year.
