One of the basic parameters of water ecosystems is temperature. Its value and distribution are of key importance for the course of biotic and abiotic processes occurring in rivers and lakes. The issue of correlations of thermal conditions with the above elements is discussed by various scientific disciplines [1][2][3][4]. Proper interpretation of the occurring correlations requires possibly detailed data concerning water temperature. Such information is collected in various ways, and covers, among other things, surface measurements [5] and measurements performed in deeper parts of waters [6].In the case of lakes in Poland, the history of measurements of water temperature dates back to the end of the 19th century [7]. Systematic observations of water temperature in lakes, however, commenced in the 1950s [8]. The measurements were coordinated by the State Hydrological-Meteorological Institute, which was later transformed into the Institute of Meteorology and Water Management (IMGW). Data concerning temperature refer to stationary (point) measurements of near-surface waters. The number of observation sites over the years has changed, partially due to frequent reorganisations Pol. J. Environ. Stud. Vol. 26, No. 5 (2017), 2159-2165 AbstractThis paper presents a comparative analysis of thermal images from Landsat satellites with in situ measurements of water temperature based on the example of three analysed lakes in Poland (Łebsko, Gardno, and Jamno). The coefficient of determination R 2 in the first two lakes reached a value of 0.95, and in the third case 0.87. The obtained results suggest high coherence of both of the sources. Satellite data obtained with such coherence with in situ measurements can be considered to be of high quality. The fact opens a new chapter concerning continuous monitoring of surface temperature of lakes in Poland, which can be considerably expanded in comparison to the current state (the measurement network is currently constituted by several tens of relatively large lakes). The issue addressed in the paper refers to a dynamic development trend in research based on teledetection information. So far, however, such methodology has not been used for detailed research on lakes in Poland. The availability of information on thermal conditions in reference to a possibly high number of lakes is of key importance in the context of the observed climate changes and the resulting transformation of water ecosystems. Continuous monitoring offers a basis for the development of applicative solutions, potentially reducing the effects of global warming.

“…On the other hand, in the vicinity of Bydgoszcz (central Poland) in the years 1931-2013, the trend of the average annual air temperature was 0.19 • C/10-year, with greater warming being observed in the cold half-year [37]. According to Ziernicka-Wojtaszek and Krużel [36] throughout Poland, the average annual temperature in the years 1981-2010 increased at a rate of 0.33 • C/10-year, which was mainly due to a strong increase in the average temperature in spring and summer. Similarly, in the border region of Poland and Saxony, the highest temperature increase was confirmed for spring and summer (from 1.5 to 1.9 • C in 1971-2010), and the lowest for winter (from 0.1 to 0.7 • C in 1971-2010) [48].…”

“…However, there is an increasingly notable need to take into account regional climate changes in economic forecasts for many sectors, including agriculture, and in preparation of recommendations for adapting farms to climate change [12,[32][33][34]. The research conducted so far in Poland concerned various aspects of climate change [35][36][37][38][39] and its impact, among others, on the shaping of agro-climatic conditions on a national scale [21,23,40], on the development of pests [25], as well as on a regional scale, which includes works describing crop-weather relationship studies [41]. A separate group is the research that is related to the development and use of climate change scenarios [33].…”

Abstract:The recognition of changes in the course of agricultural thermal periods is vital when it comes to determining appropriate measures for adapting agriculture to climate change. The present study examined changes in air temperature between 1951 and 2014 in the area of south-western Poland. A statistically significant, positive linear trend was confirmed for the annual average temperature, seasonal averages, and monthly averages in the periods spanning February-May and July-August. From the beginning of the 21st century, the period of winter dormancy of plants started increasingly later; farming and plant vegetation periods started increasingly earlier, and the period of active plant growth was prolonged. Among the considered agricultural periods, the growing season was the most prolonged. The duration of the farming period was also significantly longer, but the winter dormancy period was shortened. The negative linear trend of days when the temperature stood at <0 • C was statistically confirmed for temperature in the entire region and most of the stations. In terms of predicting the consequences of the changes that were observed today over the next decades, this is not an easy task. However, the nature of these changes suggests that further cultivation of winter crops may require far-reaching adaptation measures.

“…An increase in temperature promotes the formation of areas covered by drought or desertification (Travis et al, 2018). In Poland, the ensuing climate changes gradually reduce the thickness of snow cover in the winter, which so reduces river flows, but at the same time, in the summer, they generate intensive rainfall, thus causing destructive flood conditions (Ziernicka-Wojtaszek and Krużel, 2016;Wałęga et al, 2016;Wałęga and Michalec, 2014). In recent years, a steady decline in the groundwater levels and reduction in the capacity of underground water reservoirs has been observed.…”

Aim of the studyThe main aim of the research was to verify the thesis that formal and legal restrictions on the use of phosphorus compounds, particularly polyphosphates, in detergents extensively introduced in recent years reduced the concentration and load of this nutrient in raw sewage inflowing to the selected treatment plant. Additionally, it was tested whether the phosphorus decreasing in raw sewage reduced the concentrations and loads of total phosphorus in treated sewage, and thus reduced negative sewage anthropopressure of the water body. Material and methodsThis paper presents observations accumulated during the 15-years study (2003)(2004)(2005)(2006)(2007)(2008)(2009)(2010)(2011)(2012)(2013)(2014)(2015), the concentrations and loads of total phosphorus in domestic sewage flowing into the selected treatment plant, as well as in treated sewage discharged into the receiving water body. A total of 148 samples of raw sewage and 114 samples of treated sewage were collected over the research period. The concentration of the total phosphorus in wastewater was determined by spectrometry with ammonium molybdate. The research results were analysed with the aid of advanced statistical analysis using, among others Mann-Kendall test, Kolmogorov Smirnov test, elements of descriptive statistics, as well as regression analysis with selected significance tests. Results and conclusionsBased on the research, it was stated that multidirectional activities implemented both in Poland and Europe with the view to phosphates limitation in detergents have significantly reduced the concentration and load of this nutrient in domestic sewage inflowing to the treatment plant. Over the past 15 years, the total phosphorus concentration in household wastewater has decreased from 14.4 to 5.7 mg • dm -3 , i.e. by 60.4%. The observed tendency corresponds to the decrease in the unit load value per 1 inhabitant. This parameter decreased by 68% from 2.25 mg • person -1 • d -1 in 2003 to 0.72 mg • person -1 • d -1 in 2017. The total phosphorus concentration in treated sewage discharged from the tested sewage treatment plant decreased from 5.1 to 2.0 mg • dm -3 , i.e. by 60.8%, in the years 2003-2017. The observed regression of phosphorus content in the wastewater discharged into the sewage system translates into lowered risk of anthropopressure for flowing waters and the Baltic Sea, mainly in the aspect of initiating the eutrophication process. Based on the research, it was found Kaczor, G. B. (2020).
