Opis:: Rainfall-runoff is the active agent of soil erosion which often resulted in land degradation and water quality deterioration. Its aggressiveness to induce erosion is usually termed as rainfall erosivity index or factor (R). R-factor is one of the factors to be parameterized in the evaluation of soil loss using the Universal Soil Loss Equation and its reversed versions (USLE/RUSLE). The computation of accurate R-factor for a particular watershed requires high temporal resolution rainfall (pluviograph) data with less than 30-minutes intensities for at least 20 yrs, which is available only in a few regions of the world. As a result, various simplified models have been proposed by researchers to evaluate R-factor using readily available daily, monthly or annual precipitation data. This study is thus aimed at estimating R-factor and to establish an approximate relationship between R-factor and rainfall for subsequent usage in the estimation of soil loss in Cameron highlands watershed. The results of the analysis showed that the least and peak (critical) R-factors occurred in the months of January and April with 660.82 and 2399.18 MJ mm ha^-1 h^-1year-1 respectively. Also, it was observed that erosivity power starts to increase from the month of January through April before started falling in the month of July. The monthly and annual peaks (critical periods) may be attributed to increased rainfall amount due to climate change which in turn resulted to increased aggressiveness of rains to cause erosion in the study area. The correlation coefficient of 0.985 showed that there was a strong relationship rainfall and R-factor.

Opis:: This paper investigates the impact of Digital Terrain Model (DTM) resolution on the calculation of the sediment transport capacity coefficient LS within the Bystra catchment, employing various methods through GIS software. The study focuses on the significant role of GIS in environmental research and process modeling, emphasizing the relevance of LS coefficient analysis in morphometry, hydrology, and geomorphology, particularly in the context of agricultural soil erosion. The study presents results from calculating the sediment transport capacity factor LS using three methods for different resolutions (1, 5, 10, 30, 90 meters). LS coefficient determination relies on the catchment area map and slope map, the latter determined using two methods. The catchment area considered is that of the Bystra River, a right tributary of the Vistula, flowing through Nałęczów, Wąwolnica, Celejów, Bochotnica in the Lublin Province. Upon determining the LS coefficient, variations in results are observed, dependent on the chosen method. The discussion section highlights differences in LS coefficient maps based on resolution and method, with notable distinctions in the north-western part for a 10-meter resolution. Analyzing LS coefficient maps at different resolutions, the study observes variations in results based on the method employed. Higher LS coefficient values are noted in the river channel for a 1-meter resolution, attributed to factors such as river bed structure, building rocks, terrain slope, and climate. The conclusions emphasize the use of specific methods for determining slope rasters and highlight the Desmet and Govers method as yielding smaller variances in LS coefficient determination compared to other methods. The study recommends DTM models with resolutions of 1, 5, and 10 meters for LS modeling, considering their beneficial influence on variance and resolution. In summary, this paper contributes valuable insights into the influence of DTM resolution on LS coefficient calculations, providing a nuanced understanding of the interplay between methods, resolution, and terrain characteristics in the context of sediment transport capacity.

Opis:: W pracy wyliczono masę erodowanej gleby dla warunków Puczniewa (woj. łódzkie). Do obliczeń wykorzystano roczne maksymalne dobowe sumy opadów z lat 1972-2002. Wykonano test Kołmogorowa- Smirnowa, aby ocenić zgodność danej cechy z rozkładem normalnym, następnie opracowano dystrybuantę rozkładu prawdopodobieństwa. Dla prawdopodobieństwa 1, 20 i 50% wyliczono erozyjność opadów i straty gleby za pomocą opracowanego przez Wischmeiera i Smitha równania strat glebowych - USLE. Przyjęto następujące warianty: stoki o spadkach 5%, 10%; zagospodarowanie: użytki zielone i grunty orne; założono użytkowanie płużne - uprawa w poprzek stoku i wzdłuż. Straty gleby są ponad 10-krotnie mniejsze w przypadku użytków zielonych niż gruntów ornych.
The mass of eroded soil was calculated for the conditions prevailing in Puczniew (Poland). Annual maximum daily rainfall from the years 1972-2002 was used for calculations. Kołmogorow-Smirnow test was used to check the distribution of a given characteristics and then the probabilisty distribution was developed. For a probability of 1%, 20% and 50% the erosive rainfall properties and soil loss were calculated using Wischmeier and Smith's equation for soil losses - USLE. The following variants were adopted: slopes of the inclination of 5% and 10%; land use: grassland and arable land; arable land use with soil ploughing across and along the slope was assumed. Soil losses were over 10 times smaller in grasslands than in arable lands in Puczniew.

Opis:: Natural variability of pseudogley forest soils in the Białowieża National Park was characterised on the basis of five soil exposures. Two of them were located in a water-logged site, one in a mound one in a patch with dominance of deciduous trees, and one in a spruce biogrup. It was found that pseudogley soils of a natural moist deciduous forest show additional differentiation in the form of characteristic micromosaics. There is a pronounced impact of the species structure in a treestand, uprooted trees and hoofed mammals on the properties of the soil cover. Changes resulting from the above biotic factory were observed in all the analysed physical, physico-chemical and chemical soil parameters.

Opis:: Contamination of soil and water by various heavy metals such as Cd, Pb, Ni, Cu, and Fe is increasing day by day as a result of different activities, such as industrialization and urbanization. Lead (Pb), Cadmium (Cd), and Nickel (Ni) are examples of potential heavy metals that are neither essential elements nor have any role in the process of cell metabolism, but are easily absorbed and accumulated in different parts of a plant and living beings. This study was to investigate the translocation and bioaccumulation of heavy metals such as Pb, Ni, Cd, Cu, and Fe in Urtica dionica L and soil samples from 2 sites (uncontaminated – Koliq and contaminated – Kishnica in the Republic of Kosovo). The results revealed that in the contaminated site, the mean level of all the metals in soil and different parts (root, stalk, and leaf) of the plant were found to be significantly (p < 0.01) higher than the uncontaminated site. Multivariate analysis was used to determine the distribution of metals within the study area. The trace metal contents from different parts of these plants were determined by the use of AAS. The results revealed that Urtica dionica L. translocated high amounts of metals to its organs, especially to leaves, so that translocation factors were much higher than one (> 1). However, these concentrations of heavy metals in the soil and Urtica dionica L were higher than levels specified according to the standards in UK and Germany.

Opis:: Effects of spatial fluctuations of soil parameters are considered in a new context – considering variability of soil parameters in conjunction with non-uniform stress fields, which can locally amplify (or suppress) subsoil inhomogeneities. In this way, several design situations for the Coulomb frictional material with random tan(φ(x)) reveal a reduction of variance, which is less significant than for the standard volume averaging. When looking for an 'effective' random variable [tan(φ)]a – that is, a random variable, which is equivalent to the random field tan(φ(x)) – the Vanmarcke averaging by simple volume integrals is insufficient; it systematically overestimates effects of variance reduction, thus causing potentially unsafe situations. The new proposed approach is coherent, formally defined and more realistic.

Opis:: The Kingdom of Bhutan is located in the eastern Himalayas approximately between latitudes 26° 41’52” N to 28° 14’ 52” N and longitudes 88° 44’ 54” E to 92° 41’ 7” E. The 38,686 square kilometers of landlocked and isolated mountain country has elevations ranging from about 160 meters in the southern part to more than 7500 meters in the northern part. People habituating along the steep slope valleys with river flowing at the foot of gorges are the finest epitome of exquisite scenery for outside world. However, such slopes particularly the unstable and loose ones pose greatest threat to the mankind and the development of the country. The complex arrangement of topography, constant tectonic movement and others human induced activities accelerate the landslide which are already active. The landslide problems in Bhutan dates back to 1960s when first road construction took place in the country. Every monsoon season is marked with countless landslide across the country, among which the landslide between Phuntsholing to Thimphu highway is the most frequent and disparaging. Many people lose their valuables and lives during the summer season every year due to landslides and falling stones on the highway. This research will help in bettering the knowledge in landslides and also combating it with necessary means. The main objective of this study is to comprehend the activating processes and mechanism of the landslide as well as examine to predict the possibility of another landslide by seeking natural causes and anthropogenic factors.

Opis:: Badano zawartość wybranych metali ciężkich - kadmu Cd, ołowiu Pb, cynku Zn, miedzi Cu i niklu Ni w glebach łąkowych i leśnych oraz w wyekstrahowanych z próbek glebowych zwierząt. Stanowiska usytuowane były w różnej odległości od drogi i od źródeł emisji przemysłowych. Faunę glebową rozdzielono na grupy troficzne - saprofagi, drapieżne i fitosaprofagi, w których oznaczano metale ciężkie. Gleby na badanych stanowiskach wykazywały odczyn od słabo kwaśnego do słabo zasadowego i wilgotność w granicach 20-32%. Zawartość metali w glebie wynosiła odpowiednio: 0,63 0,94 ppm Cd; 8,8 12,53 ppm Pb; 77,75 148,78 ppm Zn; 12,17 ± 23,91 ppm Ni i 1,58 8,95 mg Cu kg–1 s.m. Wyniki badań wskazują, że stężenia metali ciężkich nie przekraczają norm określonych dla gleb Polski. Kumulacja metali ciężkich w organizmach zwierząt glebowych była znacznie wyższa niż w glebie. W największym stężeniu w organizmach badanej fauny glebowej występował Zn i Pb. Najwyższą zawartość Zn (ponad 19904 ppm) stwierdzono w organizmach drapieżców na stanowiskach leśnych. Natomiast wysokie stężenia ołowiu wykazano u fitosaprofagów w glebach łąkowych (128-421 ppm) i drapieżców na stanowiskach leśnych (200 i 500 ppm). Stwierdzono, że drapieżne zwierzęta glebowe lepiej akumulowały badane metale ciężkie w glebach leśnych niż inne grupy troficzne.
Content was studied of selected heavy metals - cadmium Cd, lead Pb, zinc Zn, copper Cu and nickel Ni in meadow soils and in forest soils and in soil animals samples extracted from soil. Positions were located at different distances from the road and from sources of industrial emissions. Soil fauna were separated into trophic groups of saprophags, predators and phitosaprophags, in which heavy metals were determined. Soils on the test sites showed little reaction from acidic to slightly alkaline and humidity within 20-32%. The range of metals content in soils amounted to properly: 0.630.94 ppm Cd; 8.812.53 ppm Pb; 77.75148.78 ppm Zn; 12.17±23.91 ppm Ni and 1.588.95 mg Cu • kg–1 s.m. The results from the studies show that the heavy metal concentrations did not exceed the standards set out for the soils of Poland. Heavy metals accumulation in soil animal organisms was significantly higher than in the soil. In the examined organisms of soil fauna, the metals in the highest concentration were zinc and lead. The highest content of Zn (> 19904 ppm) was found in the bodies of the predators in forest stands. High concentrations of lead have been demonstrated in phitosaprophags in meadow soils (128-421 ppm) and in predators in forest sites (200-500 ppm). It was found that predators of soil animals are better at bioaccumulations of tested heavy metals in forest soils (BCF > 60) than other trophic groups.

Opis:: Oil and gas production water (PW) is brought to the surface when hydrocarbon reservoirs deep within geologic strata are extracted. Large volumes of PW present environmental challenges when released to the land surface due to high levels of salinity and potentially toxic elements. The effects of PW on soil chemical properties and plant response were investigated in both growth chamber and field studies. In the growth chamber, wheat (Triticum aestivum) and red clover (Trifolium repens) were grown in soil which was flooded with synthetic PW. The PW was enriched with several metals (Na, Cu, Cr, Pb) and had an acidic pH (2.5) and EC of 33,650 dSm-1. Soil amendments included food waste compost, composted biosolids, gypsum (CaSO4) and NPK 10-10-10 fertilizer. Metal concentrations in soil and plants were determined using flame atomic absorption spectrophotometry. The food waste compost provided for maximal uptake by clover of Cu, Cr and Pb compared to all other amendments. In several soil treatments both wheat and clover behaved as metal hyperaccumulators having high bioconcentration factors (BCF, ratio of metal concentrations of plant tissue to soil). Clover was the most efficient in accumulating Cu and Cr in shoots (BCF = 22.2 and 30.6, respectively). Greatest metal uptake in both plant species occurred in either the biosolids or compost treatment. In a field study, plots were flooded with synthetic PW and grown to corn (Zea mays) and a turf mixture (Kentucky bluegrass, Poa pratensis and perennial ryegrass, Lolium perenne). Both corn and turf accumulated substantial soil Cu and Pb. Corn experienced significant die-off; however, turf survived the PW application. Turf mixtures, clover and/or wheat may be suitable for phytoremediation of PW-affected soil. Addition of organic amendments to soil may enhance metal uptake by plants.

Opis:: In recent years, an increase in environmental pollution has been observed due to rapid industrialization, unsafe agricultural practices, and increased human activities on energy reservoirs. The wide use of petroleum hydrocarbon products as energy sources has contaminated the soil and the environment, thereby posing serious threats to all life forms, including humans. This study aimed to investigate the role of poultry droppings and pig dung in enhancing the bioremediation of diesel-contaminated soil. Soil samples were collected, processed by air drying and sieving, weighed in experimental bowls (5000 g), and contaminated with 250 ml of diesel. Then, poultry droppings and pig dung were added to the soil samples in different ratios, namely 1 : 1, 1 : 2, and 2 : 1. The diesel contaminated soil sample without treatment served as the control. Thirty days after exposure to the experimental treatment regimes, the total bacterial count and the hydrocarbon-utilizing bacterial count of the diesel contaminated soil ranged from 0.4 × 104 to 2.7 × 104 CFU/g and from 0.1 × 104 to 2.1 × 104 CFU/g, respectively. The total fungal count and the hydrocarbon-utilizing fungi count ranged from 0.6 × 103 to 2.1 × 103 SFU/g and from 0.2 × 103 to 1.7 × 103 SFU/g, respectively. Bacillus subtilis, Micrococcus sp., Pseudomonas aeruginosa, Proteus vulgaris, Aspergillus niger, Penicillium sp., and Mucor sp were found to be active degraders. A significant reduction in the total aliphatic hydrocarbon (TAH) content of the diesel-contaminated soil was reported, with remediation approaching 95% in 30 days when the poultry droppings – pig dung mixture was added to the soil. The remediation of diesel-contaminated soils is important for the enhancement of the ecosystem. This study has shown that the use of farm waste such as the poultry droppings – pig dung mixture can enhance the remediation of diesel-contaminated soils.

From the Recreational Park Marcinkowski – RPM, Recreational Park Solacki – RPS, Recreational Park Wodziczko – RPW and Recreational Park Piatkowo – RPP the soil samples were collected at two depths, ie 0–10 and 10–20 cm, in the quantity of 36, 52, 32 and 34, respectively. The total content of Pb and Cd was determined in these samples, as well as some their selected physical and chemical properties. Detailed assessment of the soil contamination state was undertaken on the basis of different indices such as geochemical accumulation index (Igeo), factor (C f i ) and degree (Cdeg) of contamination. The evaluation of soils made by applying Pb-Igeo has shown that parks may be ranged as follows: RP Piatkowo < RP Solacki < RP Wodziczko < RP Marcinkowski. The concern and threat related to the impact of Pb on humans requires more restrictive limits of content, hence geochemical background (GB) values as reported by Czarnowska [20] may be considered as more adapted for protecting from potential health hazards. In the case of cadmium, the Cd-Igeo based contamination assessment allowed to organize parks accordingly: RP Piatkowo < RP Marcinkowski < RP Solacki < RP Wodziczko. Cadmium contribution in the overall contamination (Cdeg) changed as did the Cd-Igeo indices. This was mostly reflected in the RPs Wodziczko and Solacki and intermediately in the RP Marcinkowski. On the basis of the performed geochemical evaluation of soil Recreational Park Piatkowo is the sole to be classified as free from Pb and Cd contamination threat.
Rekreacyjne Parki (RP) miasta Poznań zbadano w październiku 2009 r. w celu oceny stanu zanieczyszczenia ich gleb ołowiem i kadmem. Z Parku Marcinkowskiego - RPM, Parku Sołackiego - RPS, Parku Wodziczki - RPW i Parku Piątkowo - RPP pobrano próbki gleby z dwóch głębokości (0-10 10-20 cm) w ilości odpowiednio: 36, 32, 52 i 34. Oznaczono całkowitą zawartość Pb i Cd oraz wybrane właściwości fizyczne i chemiczne tych próbek gleby. Szczegółową ocenę stanu zanieczyszczenia gleb rzeprowadzono na podstawie różnych wskaźników, takich jak: geochemiczny indeks akumulacji (Igeo) oraz spółczynnik (C współczynnik ) i stopień (Cdeg) zanieczyszczenia.
