Środowisko sedymentacji osadów przykorytowych rzek uregulowanych na przykładzie górnej Odry i górnej Wisły

Presented study focuses on vertical accretion sediment deposited during the last 250 years in the upper reaches of the rivers Odra and Vistula (Southern Poland). In this study rates of vertical accretion of floodplain sediments were determined using chronological markers provided by the first occurrence of coal dust, plastic artefacts and 137Cs. The rivers Odra and Vistula are meandering sand-bed rivers with average discharges of 41 m3s–1 and 62 m3s–1 respectively. Both of the investigated river reaches are located within submountainous basins of southern Poland: the Odra River in the Raciborz Basin and the Vistula River in the Oswiecim Basin. The aerial extent of the catchment up to the investigated area averages 4666 km2 for the Odra and 5301 km2 for the Vistula River. The valley floor slope reaches respectively 0.4 and 0.3 m/km and the sediment transportation 322 000 t/year for the Odra and 312 000 t/year for the Vistula. Maximum discharges usually occur in July in association with summer rainfalls in mountainous headwater areas. The natural processes of erosion and sedimentation on both rivers were disturbed in the 19th century when the authorities started the river regulation program for navigation purposes. The Upper Odra River and Vistula land use is characterised by agriculture and some industrial centres. The valleys itself are used for agricultural purposes. Hard coal mining started in the middle of 18th century in Katowice in 1750 AD and in Ostrava in 1763 AD. Hence these dates provides the maximum age for coal dust supply to the tributaries. Floodplain sediments were examined at sites on the Odra and on the Vistula River. Pits were excavated adjacent to the channel up to the groundwater level (approximately 3 m below surface). Sediment samples were collected from each layer of alluvia. Grain size distribution was determined by sieving at 0.25 phi intervals. The presence of 137Cs was determined for the grain size finer than 0.4 phi in gamma ray spectrometer. The coal dust layers and artefacts were found by direct visual inspection in the field. The investigated floodplain deposits of the Vistula and Odra Rivers, deposited in the zone adjacent to the river channel, are dominated by vertically accreted sets of sand and silty sand bed represent a significant flood event. Study sites on both rivers provide evidence of increasing rates of vertical accretion during the last 50 years. The very high recent sedimentation rate in Vistula and Odra sites (1,7 to 6 cm/year) is comparable with observed at other European rivers

Niszczenie naturalnych odcinków koryt rzecznych na skutek niewłaściwej zabudowy – przykład dolin Czadeczki i Krężelki (Beskid Śląski)

Channels of Czadeczka and Krężelka rivers (Beskidzie Śląski Mts) are at present subjected to regulation because of which these rivers have lost their natural character, partially still preserved. The reasons for the river regulation have been analysed. Using archival maps, the buildings erection time has been analysed on valley floors, in the immediate vicinity of river channels for the period 1790–2012. Next, the distribution of existing buildings has been compared with hydraulic structures in the channels developed in order to regulate the Czadeczka and the Krężelka reaches, such as: concrete and stone embankments reinforcing the channel banks, check dams on channel bottoms. Results indicate a strong correlation between the number of buildings on valley floors in the 20th century and channel regulation. The mechanism of destroying rare, preserved natural river reaches is based on irrational permission allowing construction of buildings in areas threatened by floods and lateral erosion of rivers. Consequently, the inhabitants, in fear of floods and erosion of land or house foundations, seek river regulation that gives them a false sense of security. Natural river reaches are destroyed though efficient protection against floods and lateral erosion is still not provided and the range of possible losses increases even more due to continued building erection

Comprehensive study of the mountainous lake sediments in relation to natural and anthropogenic processes and time (Mały Staw Lake, Poland)

The Sudety Mts. form a chain of mountains in the South of Poland and during the last 200 years were subjected to strong industrial and agricultural pressure. The records of these human-induced changes are stored in natural archives like lake sediments. For the comprehensive study, three sediment cores taken from Mały Staw Lake (Sudety Mts.) were analyzed for the concentration of K, Na, Mn, Fe, Cu, Mg, Zn, Cd, Cr, Ni, Pb and radioactivity of 137Cs and 210Pb. As a result of the studies, the bathymetry map was developed and the sources of solid material supplied to the lake were identified. The geochronology studies of the cores were performed using 210Pb method, to evaluate model of time changes in the sediment. Radioactivity of 210Pbuns (determined indirectly by 210Po) ranged from 1051 ± 64 to 12 ± 8 Bq kg−1. The 137Cs radioactivity was determined directly by gamma spectrometry and varied from525 ± 37Bq kg−1 for top layers to 9.80 ± 5.40 Bq kg−1 for the bottom of the core. Two characteristic peaks of 137Cs radioactivity related to the global fallouts after nuclear weapons testing and the Chernobyl accident were observed and used to confirm210Pb dating method. Chemometrics analysis of the chosen metal’s concentrations combined with sample dating showed distinct imprint of human activity on the studied area

Rapid river bed recovery after the in-channel mining : the case of Vistula River, Poland

The effects of in-channel wet-pit mining is nowadays widely discussed in terms of negative influence of the created pits on the river ecosystem and fluvial processes. The pits induce an alteration of natural flow or sediment transport. This paper describes the post-mining channel recovery observed in a relatively short time in a gravelly sand bed lowland river. The study was based on repeated bathymetry of the channel and grain size analyses of bed material taken from the mining area and its surrounding upstream and downstream pit. We also use calculations of possible bedload sediment movement in the studied river reach. We noticed that the excavation pit exceeded the maximum depth of 8.8 m in 2014 and, immediately after the end of mining, the bedload started to infill the pit. The bathymetric measurements in 2019 indicated that the process of pit infill was completed after five years, though the former pit is refilled with material finer than the natural bedload observed in the discussed river reach, and consists mainly of sand. The studied process of pit infilling runs continuously, even during the annual average water stages

Cytological picture of the oral mucosa in patients with gastric and colon cancer

The incidence of malignant gastrointestinal cancers in Poland has been constantly growing, which hasled to an intensification of the search for new markers of the early clinical stage of this disease. The oral cavity,as the first part of the gastrointestinal tract, has a very important role. The oral cavity presents symptoms of bothtypically stomatological and systemic diseases. Oral cancers, benign or malignant, may originate and grow in anyof the tissues of the mouth, and within this small area they may be of varied clinical, histological and biologicalfeatures. These can be lesions typically observed in the oral cavity, but also characteristic of cases where thesymptoms occur both in the mouth and in other body parts. The aim of this study was to present a cytologicalpicture of the oral mucosa in patients with gastric and colon cancer and to compare the cytological picture withthat obtained from a group of patients with no cancer, using the Papanicolaou classification and the Bethesdasystem. The study was conducted in 126 patients treated surgically in the II General and GastroenterologicalSurgery Clinic between 2006 and 2008. All patients were divided into two groups based on the type of lesions. Inboth of the studied groups, more than half of the patients did not present any abnormalities in the mucosa of themouth, lips and cheeks in the physical examination. None of the patients had erosion, ulceration or lesionstypical of leukoplakia or lichen planus. No malignant cells were detected in either of the studied groups, andthere were no well-defined lesions found in the oral cavity that would distinguish the patients with gastrointestinalcancer.

Vaginal and cervical bacterial colonization in patients with threatening preterm labor

Objectives: The aim of the following work was to evaluate vaginal and cervical colonization in patients with threatening preterm labor and comparing the frequency of colonization of the term and preterm labor groups. Material and methods: 532 pregnant women with threatening preterm labor were included into the clinical trial. The frequency of colonization was established and the frequency of colonization depending on the duration of pregnancy was checked. Results: Positive vaginal cultures were found in 29.5% of patients. The most frequent were: Escherichia coli and Streptoccocus agalactiae. There was no relationship between the duration of pregnancy, the frequency of colonization or the type of bacterial culture. Conclusions: 30% of positive vaginal and cervical cultures may indicate about the deficiency of the used method. The most frequent microorganisms remain to be Candida, Escherichia coli and GBS. However, the frequency of colonization with rare bacteria increases. Not only bacterial colonization but a group of different factors may be the reason of preterm labor
