“…Strong seasonal variation in pH, DO, BOD, and COD may result from photosynthesis, hydrological pollution, and natural chemical processes [22,23,[66][67][68]. High TOC concentrations should be considered a result of the dissolution of minerals containing calcium carbonate, which occurs in loess soils [51,55]. The high SS content causes a reduction in DO, which affects the quality of water in the river.…”

“…The land use structure of the basin is complemented by forestland (10%), urban areas (11%), and wasteland (1%). The soil cover consists mainly of Podzisols occurring in the top parts of the upland and on slopes, as well as Cambisols in the lowland parts [53][54][55]. In the years 2011-2014, the average annual air temperature was 9 • C, and the precipitation level was 570 mm.…”

The aim of the study was to analyze the results of surface water quality tests carried out in the Bystrzyca river basin. The study was conducted over four years in four seasons. The following chemometric techniques were used for the purposes of statistical analyses: the principal component analysis with factor analysis (PCA/FA), the hierarchical cluster analysis (HCA), and the discriminant analysis (DA). The analyses allowed for determining the temporal variability in water quality between the seasons. The best water quality was recorded in summer and the worst in autumn. The analyses did not provide a clear assessment of the spatial variability of water quality in the river basin. Pollution from wastewater treatment plants and soil tillage had a similar effect on water quality. The tested samples were characterized by very high electrolytic conductivity, suspended solids and P-PO4 concentrations and the water quality did not meet the standards of good ecological status.

“…Finally, potassium, a neglected nutrient, does not have a substantial health significance, except at gross levels. Skowron et al (2018) indicate that potassium concentrations can limit the distribution of larger crustaceans. However, it is an indicator of anthropogenic activities, including agricultural use (Bu et al, 2010).…”

“…However, it is an indicator of anthropogenic activities, including agricultural use (Bu et al, 2010). It is usually found in natural surface waters under 5 mg/L (Skowron et al, 2018) and between 2 and 3 mg/L in rivers (Lenntech, 2020); the values found in both rivers are higher than that, indicating the use and pollution of freshwater by artificial fertilizers with the Las Palmas river showing higher potassium values than the Colorado river (Table 1). Potassium can be used as an indicator of surface runoff because it is very soluble and can be washed by rainfall into water bodies depending on rainfall intensity and unlike nitrogen, there are no gaseous losses of potassium (Alfaro et al, 2008;Alfaro et al, 2017;Goulding et al, 2020).…”

One of Costa Rica’s driest areas is the province of Guanacaste, in the Pacific Northwest, with almost no rain during the dry season from November to April. Due to this marked seasonality, the area is covered by dry tropical deciduous forest, considered the most threatened and least known tropical ecosystem in this area. This study analyzes and characterizes the assemblages of aquatic macroinvertebrates in water bodies within the Tempisque basin. Biological water quality was measured using the BMWP′-CR index. Macroinvertebrate assemblages were analyzed using abundance, richness, and functional feeding group approaches (FFG). Partial least square (PLS) analyses were performed, and the relationships between environmental factors and macroinvertebrate assemblages are also discussed. Macroinvertebrate assemblages were dominated numerically by mayflies, caddisflies, flies, and beetles. The BWMP′-CR index showed varying biological water quality, ranging from “very bad” to “excellent,” depending on rainfall and site management. Results suggest that tropical Mesoamerican rivers contradict the “river continuum concept” because predators and scrapers displace shredders in numbers. On the other hand, the study area shows a notable high richness of the Coleoptera genera. The class Rhynchocoela (Nemertea) is reported for the first time in Central America. The results indicate that the dry forest river ecosystem shows staggering biodiversity despite the surrounding agricultural land use, probably because of their older origin concerning tropical rain forests in Central America.

“…It leads to the impoverishment of soils in humus compounds and nutrients for plants [4][5][6], the deterioration of the physicochemical properties of soils [7][8][9][10], and in the end, to lower productivity [11][12][13] and decreased crop yields [14][15][16]. The nutrients that are washed out as a result of erosion processes enter the surface water, causing pollution and eutrophication [17][18][19][20]. Incorrectly used soil easily undergoes erosive degradation [21], and reconstructing its original state is difficult, sometimes even impossible, because soil-forming processes are very slow [22,23].…”

The purpose of the work was to determine the surface and subsurface water runoff and selected constituents of the matter contained and carried out from the eroded loess slope used as arable land. The research was carried out in 2008–2011 on the Lublin Upland. The quantity of water flowing out of the slope was measured and samples were collected in order to determine the concentration of the soil suspension of nitrogen and its forms as well as phosphorus and potassium. Soil tests were also carried out and the rainfall amount and intensity was monitored. The research results show that the amount of precipitation was significantly statistically correlated with the quantity of surface and subsurface water runoff and with the precipitation and surface runoff erosion indicator EI30 (correlations at the level of r = 0.75–0.78). In addition, the mass of eroded soil was strongly correlated with the erosion indicator of rain and surface runoff EI30 (r = 0.86). The annual soil losses were from 21.1 to 173.1 Mg ha−1. The concentration of chemical components dissolved in the surface and subsurface runoff water in most cases proved to be negatively statistically correlated with the amount of precipitation and indicator EI30. The correlation coefficients (r) were at levels from −0.32 to −0.52. The annual loss of nutrients caused by chemical erosion was: nitrogen 7.210–29.949 kg ha−1, phosphorus 0.846–5.279 kg ha−1 and potassium 7.065–21.660 kg ha−1. The highest intensity of water erosion was recorded in 2010, when root crops were grown in the field.
