Opis:: Frosts are the most common natural phenomena during the transitional seasons. A frost occurs when the average daily air temperature is positive and the minimum temperature drops below 0°C. The problem of frost occurrence (especially spring frosts) is very important from the point of view of the threats related to crop plant cultivation, because it causes losses in crops when taking place during the plant growth. The aim of the study was to analyze the occurrence of air frosts in the years 2001-2018 in the region of central-eastern Poland on the basis of meteorological data. In the region of central-eastern Poland, the greatest number of days with mild, moderate and strong frosts in 2001-2018 was observed in Białowieża; conversely, it was the lowest in Warsaw. The distribution of the number of days with frosts in spring was similar. The distribution of autumn frosts, however, was different. The greatest number of days with autumn frosts was observed in Terespol and Białowieża, the least in Legionowo and Warsaw. The last mild spring frosts occurred in the period from the 3rd to 7th of April, and the earliest autumn frosts occurred between the 9th of September and the 27th of October. The dates of moderate frosts were similar. The last strong frosts occurred on the 2nd of May and the earliest on the 30th of September. The conducted analysis proved that in such a small area, there is a difference in the occurrence of high frosts observed both in spring and autumn.

Opis:: The paper presents an assessment of atmospheric drought during vegetation season defined on the basis of standardized precipitation index (SPI). The data used in this paper come from nine IMWM stations from central-eastern region of Poland, and they were registered in 1971–2005. The frequency of occurrence of vegetation season’s months was determined in particular drought classes. Spatial distribution of SPI index values was shown in all of the vegetation season’s months on the area examined. The direction and significance of values changes tendency of the analyzed index during the vegetation season were also defined. It was noticed that extreme droughts appeared four times less frequently than the normal months. Very dry months were noted most frequently in September while moderately dry – in August. The analysis of the frequency of spatial distribution of particular drought classes showed that extreme dry and very dry months occurred most frequently in western part of the area examined, while the moderately dry months also in south-eastern part. On the basis of the linear trend analysis it can be said that the SPI index values were slightly decreasing year by year.

Opis:: The objective of the work was to evaluate the effect of hydrothermal conditions on oats yields produced in east-central Poland. Hydrothermal conditions were determined based on the Sielianinov’s hydrothermal coefficient for nine IMGW (Institute of Meteorology and Water Management) stations located in the study area. The second data set consisted of oats yields compiled and published by the Main Statistical Office. Average yields as well as minimum and maximum yields were analysed. The relationship between oats yields and hydrothermal conditions was examined using a step-wise linear regression model. Correlation coefficients were negative in April and positive in June at all the stations. The relationships were confirmed by an analysis of regression equations. The regression equations also included coefficients for May and June which, however, were not statistically significant. Yield variation, described by regression equations of the dependence of oats yield on Sielianinov’s hydrothermal coefficient value was accounted for from 19 (Siedlce, Biała Podlaska) to 50% (Ostrołeka).

Opis:: The purpose of the work is to characterise pluvial conditions in central-eastern Poland from the beginning of the 21st century (2001-2020). The analysis involved seven meteorological stations of the Institute of Meteorology and Water Management - National Research Institute (IMGW-PIB): Białowieża, Legionowo, Pułtusk, Siedlce, Szepietowo, Terespol and Warsaw. The work contains the analysis of the annual and seasonal atmospheric precipitation pattern (summer, winter, spring and autumn) and its temporal and spatial variation throughout a 20-year period. Moreover, the percentage share of precipitation in each season in the annual sum was calculated. In order to analyse precipitation patterns in the study period, the Innovative Trend Analysis (ITA) was applied. The average long-term annual atmospheric precipitation sum ranged from 557 mm at Terespol to 653 mm at Białowieża. The highest seasonal precipitation sum in the studied region was recorded for the summer (218 mm) whereas in spring and autumn, precipitation stayed at a similar level and amounted to 130 and 131 mm, respectively. The lowest precipitation was recorded in winter (109 mm). The highest percentage share of the atmospheric precipitation sum was associated with summer rainfall (from 35 to 38%), whereas the lowest in winter (from 18 to 20%). Comparisons of 2001-2010 and 2011-2020 decades revealed a decline in the share of summer precipitation in the annual sum at most of the stations, and an increase in the share of winter precipitation. The ITA demonstrated that the most significant trends in precipitation change occurred in summer and winter and the directions of the trends were different for each station.

Opis:: An overview of the existing opinions combined with new geomorphological, geological, palaeopedological and TL data allow a new look at the number, age and ranges of the three Middle Polish (Saalian, Dnieperian) Glaciations in central-eastern Poland. During the first of these glaciations (Liviecian), correlated with the 10 oxygen isotope stage in deep-marine deposits (400–360 ka), the Scandinavian ice-sheet advanced in form of a rather narrow lobe, reaching only several tens of kilometres south of Warsaw. During the second glaciation (Krznanian), correlated with the 8 oxygen isotope stage (330–320 ka), it advanced in form of a wider lobe down to the northern margin of the Małopolska and Lublin uplands. In turn, during the third glaciation (Odranian), correlated with the 6 oxygen isotope stage (210–130 ka), the range of the Scandinavian ice-sheet was the largest. It stopped at the elevations of the Quaternary basement in the northern and western part of the Małopolska and Lublin uplands, reaching 330–280 m above sea level. In the study area the discussed glaciations are separated by two interglacials (Zbójnian, Lublinian = Lubavian), correlated with the Reinsdorf and Schöningen interglacials in Germany and Landos and Le Bouchet interglacials in France. The analysed data indicate that within the Odranian Glaciation, its maximum (Kamienna = Drenthe) and postmaximum stadials (Warta = Warthe), as well as two younger recessive stadials (Wkra, Mławka) should be distinguished. Due to the rather wide eastward distribution of the Scandinavian ice-sheets during the two younger glaciations, an attempt has been made to correlate them with the two Dnieperian glaciations in the Ukraine.

Opis:: The data used in this paper come from nine IMGW stations from central-eastern region of Poland and they were registered between the years 1971–2005. On the basis of daily precipitation sums analysis during vegetation season, the number of days with precipitation was determined in particular classes. In central-eastern Poland during vegetation season days with very little and little precipitation were noted most frequently. Very little precipitation occurred most frequently in April; little, moderate and moderately strong precipitation - in June, and strong precipitation - in July. Whereas very strong precipitation was noted most frequently in June and July. Days with very little and little precipitation were noted most frequently in northern and north-eastern part of the area examined. While the number of days with moderate, moderately strong and strong precipitation showed little spatial diversity. Very strong precipitation was noted the most frequently in the area of Legionowo and Ostroleka. The number of days with very little precipitation during vegetation season was decreasing in subsequent years of the study. Statistically significant negative directional coefficients of the trend were noted most frequently in April. The number of days with very strong precipitation was also decreasing significantly in most of the stations.

Opis:: Zmiany klimatyczne w Polsce coraz częściej powodują straty plonów z powodu wystąpienia suszy. Jedną z miar wykorzystywanych do oceny kształtowania się warunków wilgotnościowych danego obszaru jest klimatyczny bilans wodny. Uwzględnia on zarówno opady atmosferyczne, jak i ewapotranspirację. W pracy wykorzystano dane z ośmiu stacji IMGW z rejonu środkowowschodniej Polski, zarejestrowane w latach 1971–2005. Obliczono miesięczne wartości klimatycznego bilansu wodnego w okresach wegetacyjnych (IV–IX) badanego wielolecia. Stwierdzono, że w środkowowschodniej Polsce w miesiącach okresu wegetacyjnego dwa razy częściej występują ujemne klimatyczne bilanse wodne niż dodatnie. Ujemne wartości tego wskaźnika najczęściej notowano w miesiącach wiosennych, a dodatnie we wrześniu. Najmniejsze niedobory wodne notowano w północnowschodniej części badanego obszaru, a największe w części zachodniej. Analiza wykazała, że wartości klimatycznego bilansu wodnego charakteryzują się dużym zróżnicowaniem. Stwierdzono, że wartości te zmniejszają się istotnie, średnio o 5 mm na rok.
Climatic changes in Poland are more and more often the reason of crop losses due to the drought occurrence. One of the measures used to evaluate the moisture conditions in particular area is climatic water balance. It takes into account both precipitation and evapotranspiration. Data used in this paper come from eight IMGW stations in central-eastern region of Poland from the years 1971–2005. Monthly values of climatic water balance during vegetation season (April–September) were calculated for the examined years. Negative climatic water balances were found to occur two times more than positive balances in central-eastern Poland during vegetation seasons. Negative values were most often observed in spring months, while positive – in September. The smallest water deficiency was noted in north-eastern part of the examined area while the largest in western part. The analysis showed that the values of climatic water balance were quite variable. These values decreased significantly by about 5 mm per year on average.

Opis:: The aim of the study was to estimate the content of Pb, Cd, Zn, Mn, Cu, Fe, Ca in meat and liver of male kids and ram lambs fed mixtures containing 10% of flax seeds. Castrated male kids (n = 7) of White Upgraded breed and castrated ram lambs (n = 7) of Polish Lowland sheep fattened up to about 35 kg of body weight were used as experimental material. The animals were fed mixture CJ ad libitum, supplemented with 10% of flax seeds and meadow hay as a structural supplement. Contents of the chemical elements were analysed in samples of longissimus dorsi muscle. The content of Cd (0.01 mg kg–1) in male kid meat was lower than in ram lamb meat (p ≤ 0.05). Similarly, Pb content was lower (p ≤ 0.05) in male kids (0.04±0.003 mg kg–1) than in ram lambs (0.07±0.002 mg kg–1). Slightly lower content of Pb (by 0.01 mg kg–1) and Cd (by 0.01 mg kg–1) in male kid liver was determined, and the differences were statistically insignificant. Significantly larger (p ≤ 0.01) Cu content (1.14±0.07 mg kg–1) in muscular tissue of ram lambs was also stated. Male kid meat, however, was richer in Mn, Fe, Zn and Ca, with the differences tested at p ≤ 0.05 and p ≤ 0.01. The liver was an organ which accumulated not only Pb and Cd but also Cu, Mn and Zn both in ram lambs and male kids. Especially high level of Cu and Mn in liver was found, which could be the result of a high content of the chemical elements in mixtures. Moreover, significantly larger content of Ca (15.24±1.68 mg kg–1) in ram lamb liver compared to male kid liver was stated. On the other hand, muscular tissue of male kids contained more Ca (21.94±1.74 mg kg–1) than that of ram lambs. The content of chemical elements (especially heavy metals) in muscular tissue and liver was lower than the norms established by the Minister for Health and the European Committee, which prove that the tested food products were fully safe for consumption.
Celem badań było określenie zawartości Pb, Cd, Zn, Mn, Cu, Fe, Ca w mięsie i wątrobie koziołków i tryczków żywionych mieszanką pełnoporcjową z 10% udziałem nasion lnu. Materiał doświadczalny stanowiły wykastrowane koziołki (n = 7) rasy białej uszlachetnionej i wykastrowane tryczki (n = 7) polskiej owcy nizinnej, tuczone do masy ciała ok. 35 kg. Zwierzęta doświadczalne otrzymywały do woli przemysłową mieszankę treściwą CJ, dodatek 10% nasion lnu oraz siano łąkowe jako dodatek strukturalny. Próby do analizy pobrano z mięśnia najdłuższego grzbietu (m. longissimus dorsi), w którym oznaczono zawartość pierwiastków. W mięsie koziołków stwierdzono niższą zawartość Cd (0.01 mg kg–1) ni¿ u tryczków – p ≤ 0.05. Podobnie poziom Pb był niższy (p ≤ 0.05) w grupie koźląt (0.04±0.003 mg kg–1) w porównaniu z tryczkami (0.07±0.002 mg kg–1). W wątrobie koźląt stwierdzono nieznacznie niższy poziom Pb oraz Cd (0.01 mg kg–1) – różnice nieistotne statystycznie. Istotnie wyższą (p ≤ 0.01) zawartość Cu (1.14±0.07 mg kg–1) w tkance mięśniowej stwierdzono u tryczków. Natomiast mięso koziołków było bogatsze w Mn, Fe, Zn i Ca – różnice p ≤ 0.05 i p ≤ 0.01. Wątroba była narządem koncentracji nie tylko Pb i Cd, ale Cu, Mn i Zn zarówno u tryczków, jak i koziołków. Zaobserwowano szczególnie wysoki poziom Cu i Mn w wątrobie, czego przyczyną mógł być wysoki poziom tych pierwiastków w paszy. Ponadto w wątrobie tryczków stwierdzono istotnie (p ≤ 0.01) wyższy poziom Ca (15.24±1.68 mg kg–1) niż u koziołków. Natomiast tkanka mięśniowa koziołków zawierała więcej Ca – 21.94±1.74 mg ≤ kg–1. Stężenie pierwiastków, szczególnie metali ciężkich, w tkance mięśniowej i wątrobie było poniżej dopuszczalnych norm podanych przez Ministra Zdrowia i WE, co kwalifikuje je jako surowce żywnościowe w pełni bezpieczne do spożycia.

Opis:: The article concerns the controversy on the four hypotheses of karst origin of lake basins in Upper Cretaceous carbonates of the Łęczna-Włodawa Lakeland (central-eastern Poland; Fig. 1). The hypotheses assume that the lake basins (Fig. 2) developed in the Holocene with the active morphogenetic participation of subartesian waters. The main problem is the lack of references to the laws of thermochemistry and kinetics of dissolution of carbonate rocks. In the Ca2+ and HCO3 concentrations in the medium solution (Tab. 1), rationally adopted for this work, the values of the enthalpy, entropy and Gibbs potential/free energy have been calculated (formulas: 9, 10 and 11). Using the conductometric method (Tab. 2, Figs. 3 and 4), the kinetics of dissolution of carbonate basement rocks, i.e. reaction rate v (formula 13), rate constant k (14a), and reaction half-life t1/2 (15), have also been determined. These investigations show that the theses formulated in the hypotheses are not acceptable. The rationale for such an assessment is the incompatibility of the assumptions of the hypotheses with the first and second law of thermochemistry. The second important reason is the ignoring of chemical kinetics as an indirect indicator of the time of the formation of the karst features. According to the author, the main period of the formation of lake basins, in terms of their origin, should be associated with palaeokarst of Neogene deposits.

Opis:: Wyznaczono daty początku i końca oraz liczbę dni termicznej zimy (1971–2005). Za początek analizowanej pory roku przyjęto uważać datę przekroczenia średniej dobowej temperatury powietrza przez próg t≤0oC. Kierunek oraz istotność tendencji zmian określono na podstawie równań trendu liniowego. Średnio termiczna zima w środkowo-wschodniej Polsce rozpoczynała się 10 listopada i trwała do 15 marca. Daty jej początku i końca charakteryzowały się dużą zmiennością. Najdłużej period ten trwał w północno-wschodniej części badanego obszaru, a najkrócej w północno-zachodniej. Liczba dni czasu trwania termicznej zimy nie wykazywała istotnych tendencji zmian. Długotrwałe zimy (od 110 do 130 dni, od 140 do 160 dni) występowały najczęściej w Białowieży, a najkrótsze (90–100 dni) w Ostrołęce.
The start and end dates and the number of days of thermal winter (1971–2005) were indicated. The start of the analyzed season is assumed to be the date of exceeding the average daily air temperature above the level of t ≤ 0o C. The direction and significance of changes tendencies were determined on the basis of linear trend equations. Thermal winter in central-eastern Poland on average began on November 10th and lasted till March 15th. Its start and end dates were characterized by high variability. This period lasted the longest in north-eastern part of the analyzed area while it was the shortest in north-western part. The number of days of thermal winter duration did not show any significant changes tendencies. Prolonged winters (from 110 to 130 days, from 140 to 160 days) occurred the most frequently in Bialowieza, while the shortest (90-100 days) in Ostroleka.
