Opis:
Zoonotic serotypes of Salmonella enterica subsp. enterica are an important biological factor that poses a threat to public health, and broilers are often asymptomatic carriers of these bacteria. The aim of this study was to analyze the prevalence of Salmonella spp. and Salmonella serotypes in broiler chicken flocks in northern Poland in 2014–2016. The study was conducted on commercial flocks monitored by the Institutes of Veterinary Hygiene in Gdańsk and Olsztyn in 2014–2016. A total of 4,331 samples were investigated. Identification of Salmonella spp. was performed by a culture-dependent method followed by biochemical and serological confirmation tests, in accordance with Polish Standards. The total percentage of infected flocks in northern Poland reached 1.57%. The prevalence of Salmonella spp. in broiler chickens decreased from 2.19% in 2014 to 1.22% in 2016. The percentage of flocks infected with S. Enteritidis and S. Typhimurium was 1.18% and 0.12%, respectively (S. Enteritidis and S. Typhimurium were detected in 1.29% of flocks). The most common serotypes that had not been covered by the control programme were S. Mbandaka (0.14%), S. Infantis (0.07%) and, sporadically, S. Kentucky and S. Anatum. The percentage of infected flocks was higher (by 0.26%) in the Pomeranian Region than in the Region of Warmia and Mazury, and it increased over the analyzed period – the highest number of positive samples were found in 2016 (2.04%). In the Region of Warmia and Mazury, the percentage of infected flocks was highest in 2014 (3.08%); in 2014–2016, the number of positive samples decreased steadily to reach 0.41% in 2016. In the analyzed regions, the incidence of human salmonellosis was correlated with the percentage of infected broiler flocks.

Opis:
The possible existence of a circular structure in the Kościerzyna region (northern Poland) was suggested in two papers in the 1980s. The current studies were aimed at verifying this hypothesis. Analysis of a digital terrain model of the pre-Quaternary surface relief as well as of the present terrain revealed the existence of a large structure of ca. 50 km in diameter. Its geometry was established based on a model of the Neogene/Pliocene surface and identifiable lineaments. Its characteristic feature is the presence of rim-like forms, an internal plateau, and a “high” in the centre. The structure is estimated to date from before the Pleistocene. The circular structure has been reshaped by glacial erosion and accumulation, and is now buried under Quaternary deposits. The existence of the Kościerzyna circular structure was confirmed by conducted studies, but my hypothesis of an impact origin is still uncertain and needs to be confirmed by future research.

Opis:
Research by the Polish Geological Survey has been carried out along the southern Baltic coastal zone over a distance of 38 km. The Baltic Sea is classified as non-tidal, and its southern coasts are built entirely of weakly lithified sedimentary rocks. These deposits form three main types of coast, namely cliffs, barriers and alluvial coasts (wetlands), with the research focusing on the first two. Methods including remote sensing, mapping (geological, hydrogeological), offshore survey (bathymetric and geophysical measurements), laboratory analyses and modelling revealed a number of natural hazards. These are, respectively: (1) permanently occurring hazards, causing material damage such as: landslides, coastal erosion and seabed erosion; (2) incidental hazards such as dune breakage and storm surge overflow and (3) hypothetical threats that may occur in the future, such as hydrogeohazards defined here as flooding resulting from groundwater level rise or more rarely, earthquake threats.

Opis:
The abundance of the eel (Anguilla anguilla) in Europe has been on the decline in recent years, to the extent that this fish species is now considered to be threatened with extinction. Hence, the current implementation of the Eel Management Plan in Poland, whose aim is to restore w stocks of this fish. The main natural habitats of eel are the transitional waters of the Vistula and Szczecin lagoons and lakes in northern Poland. The eel is highly valued by many consumers for the taste and texture of its meat. The aim of the study was to determine differences in concentrations of macro- and microelements and toxic metals in muscles of the eel as a function of each specimen’s length, mass and the origin. The results of the study also served an evaluation of the health benefits and risks to consumers of eel meat with regard to the content of macro- and microelements and toxic metals. Specimens of the eel (Anguilla anguilla) were caught in 2011-2013, in five regions of Poland: the southern Baltic, inland lakes in northeast Poland, the Vistula and Szczecin lagoons, and in the Vistula River. The concentrations of Ca, P, Mg, Na, K, Fe, Sr, Zn and As were determined with optical emission spectrometry. The flameless atomic absorption spectrometry method was used to measure concentrations of Cu, Cd and Pb. The content of Hg and Se were determined with atomic absorption, those of mercury with cold vapour, and of selenium with hydride generation. The concentrations of macro- and microelements in most instances, with the exception of P and Zn, were negatively correlated with the eel’s length and mass, which indicated that small fish contained more minerals than large specimens. The eel is a rich source of phosphorus, zinc, selenium and iron, and it can supply significant quantities of the daily requirements of human consumers for these minerals. The other minerals occurred in eel muscle at levels that ranged from 2 to 6% of human daily requirements. Among the toxic metals, mercury was the cause for concern, while cadmium and lead occurred at low levels in all of the specimens examined regardless of their size. The mean concentration of mercury ranged from 0.147 to 0.273 mg kg-1 and was positively correlated with specimen length and mass. The content of mercury in large eel exceeded 0.500 mg kg-1, while small eel (up to 70 cm) contained lower levels of mercury. Large eel exceeding 70 cm can pose a threat to the consumer’s health because of mercury, and especially its organic from of methylmercury. This is why consumers should limit long-term consumption of larger eel, while it is safe to consume smaller specimens since they contain less mercury and more minerals than do large eel.

Opis:
The Silurian deposits of Pomerania occur in the foreland of the Pomeranian Caledonides which are the SE continuation of the Danish-North-German Caledonides. The Silurian sequence in Pomerania is represented largely by graptolitic clay- and mud-shales deposited in a hemipelagic environment. From the Wenlock through Late Ludlow, slow deposition of hemipelagic clays and muds was repeatedly interrupted by silty debris flows and turbidity currents. Many of the siltstone interbeds were reworked by bottom currents. Clastic material was sourced from the Caledonian accretionary prism stretching along the collision zone of Baltica and East Avalonia. The Silurian shale-siltstone succession in Pomerania represents a Caledonian exoflysch i.e. syn-collision clastics accumulated in a foredeep developed on the East European Craton. The diachronous appearance of siltstone interbeds in the graptolitic shales indicate that collision between Baltica and East Avalonia was associated with sinistral strike-slip movement along the edge of the East European Craton.

Opis:
The large negative residual Bouguer gravity anomaly in northern Poland called the Pomerania Gravity Low (PGL) was analysed using Parker's ideal body theory. A residual gravity anomaly along the profile was inverted to find bounds on the density contrast, depth, and minimum thickness of its sources. As the ideal body reaches the surface, the greatest maximum negative density contrast is -0.038 g/cm3, while the body itself has a thickness of 52 km. If 8 km is taken as a depth to the source body top, the density contrast must correspond to at least -0.092 g/cm3, with a maximum allowable thickness of 18 km. The ideal body inversions show that the depth to the body top cannot exceed 15 km. Assuming a geologically reasonable maximum density contrast as small as -0.2 g/cm3, the source body top can be no deeper than 11.5 km, and its thickness greater than or equal to 6 km, assuming it extends up to the Earth surface, or greater than or equal to 7 km, when its top is below 8 km depth. It can be hypothesized that the main source of the negative gravity anomaly is reIated to a predominance of felsic rocks in the Paleoproterozoic Dobrzyń Domain of the East European Platform basement.

Opis:
The provenance of clastic material in the oldest part of the sedimentary cover of the East European Craton, in northern Poland, is analysed. Analysis of the Żarnowiec Formation sandstones (Upper Vendian-lowest Cambrian) confirm earlier views of a local origin. The crystalline basement in the Kościerzyna IG 1 region mainly yielded enderbitic detritus while that in the Gdańsk IG 1 region provided migmatitic detritus. Triangle diagrams of the overlying, mature, sandy marine Cambrian show unequivocally that the detritus was transported from the craton interior. Analysis of mono- and polycrystalline quartz and cathodoluminescence (CL) analysis indicates erosion of metamorphic, magmatic and sedimentary rocks, and this is confirmed by CL observations of zircons. These results are consistent with the view that the Upper Vendian and Cambrian strata on the Pomeranian Caledonides foreland were formed on the passive margin of Baltica.

Opis:
Lower Paleozoic deposits have been noted in the western part of the Baltic Depression belonging to the Precambrian platform as well as in the Koszalin-Chojnice Zone that represents a hypothetical fragment of the Caledonian fold and thrust belt. Generally, the boundary between these regions is considered to run along faults belonging to the Teisseyre-Tornquist Zone. The deposits have been widely recognized in the East European Craton, and their entire lithological column has been drilled through in on- and offshore boreholes. New constructed lithofacies-thickness maps have updated the lithofacies diversity and thickness changes of the Ediacaran-lower Paleozoic deposits. The sedimentary infill of the Baltic Basin begins with deposits of the arnowiec Formation ascribed to the uppermost Ediacaran and lowermost Cambrian. The upper part of the Lower Cambrian comprises sandstones and mudstones and the Middle Cambrian is made of sandstones, mudstones and claystones. Upper Cambrian to Tremadocian strata are represented by dark bituminous shales. Arenigian to Ashgillian deposits are developed as thin calcareous-muddy deposits. Silurian strata represent a thick (over 3000 m) succession of siltstones and shales with subordinate calcareous intercalations in the upper part of the succession (Pridoli). In the Koszalin-Chojnice Zone only, fragments of tectonically disturbed Ordovician and Silurian shales and siltstones have been recognized.

Opis:
Plants have always played an important role in funeral customs. To understand their true meaning, close cooperation between the archaeologist and the archaeobotanist is needed, not only during the final interpretation, but from the very beginning, at the stage of collecting materials. In the article, plants’ identification, using both pollen and macroremainsanalysis, was described, based on one of the children’s burial from the Holy Trinity Church in Byszewo (18th/19th centuries). The filling of the coffin pillow consisted of numerous hop (Humulus lupulus) macroremains, the representation of which was very low in pollen sample. This is due to the fact that only female specimens of hop were inserted into the coffin. To determine the reason for using hops in funeral practices in Byszewo, ethnobotanical data was used. The following research indicates the need for the cooperation between two methods of plant identification. It will allow misinterpretations of botanical findings to be avoided

Opis:
Lacustrine organic sediments were sampled at Gronowo (Chełmno Plateau) and Piotrkowo (Dobrzyń Plateau) located within a widespread system of subglacial channels separated by the large Drwęca ice-marginal valley. They have been examined for their pollen, plant macro-remains and geochemistry, as well as radiocarbon-dated. The analyses have allowed reconstructing the evolution of the area and presenting an asynchronous appearance of two lakes. Before lake sedimentation, glaciolimnic sediments from the end of Plenivistulian, at the site of Piotrkowo, was dated. Lacustrine sedimentation started during the Allerød at Gronowo, and during the Preboreal at Piotrkowo. The different age of the two lakes is ascribed mainly to differences in the Late Glacial drainage conditions which directly affected the melting away of dead-ice blocks buried in the channels.
