Opis:
A multi-disciplinary approach is indispensable for adequate acid rock drainage (ARD), mineral leaching impact, and groundwater management. Groundwater is a valuable resource, and it is critical to protect as well as mitigate the effects of pollution such as ARD in the mining environment. Mine waste storage facilities (waste rocks and tailings) are potential ARD sources capable of degrading groundwater reserves. This research investigated and reported the application of a case study of multivariate statistical and spatial variability of selected parameters associated with ARD in groundwater around WRD and TSF at mine sites. Water quality analysis data of seventy water samples from 10 boreholes located at the WRD and TSF mine were utilised in this study. The correlation matrix and principal components analysis was applied to the data set to determine the associated variability in groundwater in relation to ARD. Geostatistical analysis was used to produce contour maps to ARD principal components of the study site, using ordinary kriging of the best fit models. The application of multivariate statistical and geospatial analysis in groundwater quality assessment with coupled soil and groundwater modelling of flow and transport at waste rock dump and tailings storage sites provides an essential tool for exploratory data analysis, and spatial extent determination of the relationship between various data sets significant to acid rock drainage.

Opis:
Mechanical site preparation (MSP) is commonly used to enable forest regeneration of clear-cuts. Less intense methods may be more suitable from an environmental point of view, but such a method can result in the lack of natural regeneration. We compare the influence of three MSP methods on natural regeneration of Scots pine. The methods differ in their degree of soil disturbance. The effects of MSP by forest plough (FP), active plough (AP), and forest cutter (FC) on density, quality, and biometric parameters of one-year old seedlings were determined. The highest density of seedlings was obtained in the FP treatment (188,000 seedlings ha–1). The seedling density was significantly lower in the AP method (121,000 seedlings ha–1), and in the FC variant (36,000 seedlings ha–1). The best quality seedlings were found in the FC variant, and the worst – in the FP treatment. Most biometric parameters of seedlings did not differ by MSP method, except for the root length and root:shoot ratio. By the end of growing season, in the FP treatment, 1-year old seedlings formed a top bud more than twice as often as the seedlings from the AP and FC treatments. The FP method led to the best Scots pine natural regeneration. The results obtained in the FC variant were not as good as in the FP method, though they were still acceptable from the silvicultural point of view. The FC method was the least intensive method of site preparation, yet it is considered the most appropriate from the environmental (soil protection) point of view.

Opis:
The paper presents the results of the monitoring of the selected physicochemical properties of the Jasień River waters (in Łódź, the third biggest city of Poland) and their changes under the influence of drainage of a railway station Łódź Fabryczna construction site. Even 25 years ago the Jasień River was a receiver for the sewage from the Łódź textile factories. The drainage of the excavations and disposal of the water into the Jasień River was started on January 2014 and changed stable hydrological, physical and chemical regime of the river once again. In a consequence, average monthly flows exceeded the Jasień River flow in its upper section by six times, and at the beginning by even ten times. Chloride concentration was systematically growing over the study period. This growth and higher water pH were probably associated with increasing level of contaminants in the discharged water and its gradually decreasing uptake. Average annual water temperature increased and a decrease in its amplitude was observed. The annual conductivity and pH patterns became more uniform and the changes in pH followed a clear trend of monthly changes. Water turbidity increased by two times and during summer floods this parameter was often even a few times higher than before the drainage commenced. Chlorides improved water conductance and sodium and potassium increased basicity.
Wody Jasienia od niedawna znajdują się pod wpływem odwodnienia terenu budowy podziemnego dworca Łódź Fabryczna. Rzeka Jasień jeszcze ćwierć wieku temu była odbiornikiem ścieków z łódzkich fabryk włókienniczych. Zrzut z odwodnienia wykopu budowy podziemnego dworca Łódź Fabryczna został skierowany w styczniu 2014 r. do koryta Jasienia i zmienił stabilny reżim hydrologiczny i fizykochemiczny tej niewielkiej rzeki. W jego efekcie średnie miesięczne przepływy w górnym biegu Jasienia zwiększyły się sześciokrotnie, a początkowo nawet 10-krotnie. Stężenie chlorków systematycznie zwiększało się w okresie badań. To zwiększenie, a także zwiększenie zasadowości wody były prawdopodobnie związane ze zwiększeniem zanieczyszczenia wód odpompowywanych z wykopu. Wzrosła także średnia roczna temperatura wody, a jednocześnie zmniejszyła się jej amplituda. Roczne przebiegi przewodności elektrycznej właściwej i odczynu wody uległy wyrównaniu, a zmienność odczynu wynikała z wyraźnego trendu zmian miesięcznych. Mętność wody zwiększała się dwukrotnie w ciągu roku, zaś podczas letnich wezbrań okazywała się często nawet większa niż przed rozpoczęciem odwadniania. Chlorki zwiększyły przewodność elektryczną właściwą wody, a obecność jonów sodu i potasu spowodowała zwiększenie zasadowości wody. Zaobserwowane zmiany rodzą pytania o trwałość reżimu hydrochemicznego Jasienia po zakończeniu budowy dworca.

Paper discusses the influence of site quality on self−thinning process in silver birch stands growing on abandoned farmlands in Mazowieckie region (central Poland). Number of trees in a stand decreases with increasing age. The better the site (the higher site index value), the higher number of trees can be observed. However at the age of 10 difference between sites of various quality (site index) become insignificant. There is no need to include site index into the self−thinning models for young silver birch stands.

Opis:
Taking into account the progressive degradation of soils it is important to assess their quality. Soil quality depends on a large number of physical, chemical, biological and biochemical properties. In the publications available, there are presented three approaches regarding the use of soil properties to estimate soil quality: (1) the use of individual properties, (2) the use of simple indexes and (3) the use of complex indexes derived from combinations of different properties. The purpose of this study was to investigate the possibility to use enzymes as indicators of forest soil quality. Experimental plots (43) were located in central Poland. The study was carried out in a number of diverse fresh forest sites. To assess the quality of forest soils dehydrogenase and urease activity and the degree of base saturation were used. One of the final conclusions point out that enzymatic activity indicates current site condition as well as the changes that occur in soil better than soil physical and chemical properties. In other words, in comparison to soil enzymatic activity, soil physico-chemical properties constitute a less sensitive indicator of soil changes.

Opis:
The numerical valorisation of soil quality is based on the determination of a set of soil properties adjusted to a given soil function in the ecosystem. The obtaining of an index is based on: determination of soil properties, their conversion into abstract numbers called indicators, index calculation and its practical application. The first proposal of a forest soil quality index was the Forest Soil Trophism Index – ITGL calculated for the soils presented in the Atlas of forest soils in Poland. The calculation of the ITGL was based on the following soil properties: percentage share of very fine sand and coarse silt fraction (Ø 0.1−0.02 mm) and silt and clay particles (Ø <0.02mm), reaction, sum of exchangeable bases and organic matter decomposition degree, content of skeletal parts. Its variability in the forest soils of Poland oscillates between 6.0 and 43.0 and its application in the valorisation of forest sites is multidirectional.

Opis:
The correct assessment of the site conditions is the basis of the good management of forest areas. The aim of this study was to find a set of soil properties, which allow separating the diverse sites in terms of the soil productivity. We used 180 locations in the Carpathians and the Sudety Mountains for testing. The study plots were located in transects from the foothills to the top along the slopes, taking into account the variability of site conditions, geological substrate and exposition. The index was calculated on the basis of the content of <0.02 mm particles, the sum of exchangeable base cations, soil acidity and the ratio between total N content and organic C in the humus−mineral horizon. The soil trophic index for mountain areas (SIGg) that include the climatic factor was introduced. The factor is defined as the 650/altitude ratio for a given point above sea level. In the mountains, the content of <0.02 mm fraction, the sum of exchangeable base cations and soil acidity were determined in the column of 1 m² of the soil cross section and depth of 1 m (1 m³ of volume) due to the lower depth of the soil profile. The SIGg correctly separates soil of different productivity as the properties closely associated with the stable elements of the soil, expressing its production and properties, which reflect the current state of the soil environment, were used in the construction SIGg.

Opis:
Bank filtration (BF) is a nature-based solution that can provide safe drinking water at a low cost, in being a green technology that benefits from natural ecosystem services and saves energy as well. The objective of the present paper is to evaluate the potentiality of a new site for bank filtration along a surface water source that experiences periods of both high and low flow. This site is located along the Ismailia Canal in the eastern Nile Delta fringe of Egypt. The present evaluation is based on exploratory drilling, installation of monitoring infrastructure and monitoring of both water level and water quality parameters for one year. The site has favourable hydrogeological conditions; the mean hydraulic conductivity of aquifer materials (sand and gravel) is 18.98 m/day. Moreover, there is a hydraulic connection between canal and aquifer; under steady conditions, the canal feeds the aquifer. Using different tracers, such as Cl, EC, Sr and SO4, the average bank filtration share is in excess of 95%. BF has reduced the particulates (turbidity) by 96%, total coliform by 99 % and total organic carbon (TOC) expressed as ultra-violet absorbance at 254 wavelengths (UVA254) by 44%. In addition, BF reduces concentrations of disinfection by-products due to its ability to remove organic matter. The potential degradation of TOC in the canal bed sediments may cause the release of iron (Fe) and manganese (Mn) to the bank filtrate water; this process is exaggerated during low-flow periods. Compared to conventional water treatment, BF is a cost-effective green technology, because no chemicals are used and no waste products are generated.

Opis:
Biologically active substances of plant pesticides deposited on pesticide burial sites can be a source of toxic substances threatening underground and surface waters and consequently drinking water. Mercury usually makes up about 0.7% of the total waste content, copper - 4.3%, zinc – 4%, and chloroorganic compounds – 29.9%. The aim of the work was to evaluate the quality of the environment in the vicinity of a pesticide burial site in Podlasie, Poland. The study was carried out in September-November 2009. The burial site comprised three containers consisting of concrete circles insulated with roofing paper and cement. Samples for determinations were collected from the immediate surroundings of the pesticide burial site. Soil samples were also taken from three holes made to the depth of 0.2-0.4 m and situated 15 m away from the burial site depth and from two sites under the concrete well (0.5 m and 1.0 m). Moreover, water samples from two piezometers and samples of plants growing up to 30 m distance (pine needles, grasses, mushrooms, birch and alder leaves and twigs, cabbage, and maize) were collected as well. Copper, mercury and zinc were determined in samples of waters, soils and plants. The metal content in soils corresponded to the natural levels; the concentrations in plant samples indicated no accumulation and the water samples were not determined to contain elevated concentrations of the above metals. It has been proven that the concrete wells were hermetic and the environment around the pesticide burial site has not been polluted.
Biologicznie aktywne substancje pestycydów składowanych w mogilnikach mogą być źródłem substancji toksycznych migrujących do wód podziemnych, powierzchniowych, a w konsekwencji do wody pitnej. W przeciętnym mogilniku ilość rtęci wynosi 0,7% masy wszystkich odpadów, miedzi 4,3%, cynku 4%, zaś związków chloroorganicznych 29,9%. Praca przedstawia jakość środowiska otaczającego mogilnik pestycydowy na Podlasiu. Badania prowadzono w okresie wrzesień-listopad 2009 roku. Mogilnik zbudowany jest z betonowych kręgów studziennych izolowanych lepikiem. Próbki do badań pobierano w bezpośrednim sąsiedztwie mogilnika. Próbki gleby pobierano z głębokości 0,2-0,4 m w odległości do 15 m od mogilnika, próbki gleby spod studni z głębokości 0,5 oraz 1,0 m pod dnem. Próbki wody pobierano z dwóch piezometrów, zaś roślin w promieniu 30 m od mogilnika (igły sosny, trawy, grzyby, dynie, brokuły). W próbkach wody, gleby i roślin oznaczono miedź, cynk i rtęć. Gleby cechuję się naturalną zawartością tych pierwiastków, stężenia metali w próbkach roślinnych można określić jako akumulację małą, a rośliny jako nie zanieczyszczone, nie zanotowano także zwiększonej ilości pierwiastków śladowych w wodach podziemnych. Może to świadczyć, że ten mogilnik jest szczelny, a środowisko wokół niego nie jest zanieczyszczone.

Opis:
In recent years, we face a massive dieback of Norway spruce stands in Poland. The cause of this process may lay in the way of their monocultural silviculture. The correct assessment of the habitat conditions and soil properties in particular is the basis of the proper management of these forest areas. The aim of this study was to verify application of the trophic soil index for mountain areas (SIGg) in the assessment of site conditions for spruce stands with different health condition. Three types of spruce stands were distinguished: degenerated, weakened and stable. In total, 32 study plots were established in following forest districts in southern Poland: Ustroń, Wisła, Bielsko, Węgierska Górka, Jeleśnia, Ujsoły and Lądek Zdrój. The SIGg was calculated on the basis of <0.02 mm fraction content, the sum of exchangeable base cations, soil acidity and the total content of N and organic C in the humus−mineral horizon. These attributes are useful to determine the potential productivity of the soils did not differentiate visibly the analyzed stand variants. The soil in degenerated and weakened spruce stands showed higher degree of acidity and less the content of base cations compared to soils of stable spruce stands. Mountain trophic soil index can be applied in the assessment of the forest sites potential. Although it does not enable to monitor the disturbances in the nutrients circulation, the detailed analysis of its components allows for precise assessment of the forest sites status.

Opis:
Investigations were conducted on 48 Scots pines coming from 16 natural sites in northern Poland. This study was an attempt to analyse relationships between crown parameters of model trees and the stem conduction area in terms of site conditions, age and social diversification of the stand. Analyses showed that there is a strong dependency between crown volume and the volume and area of the xylem (sapwood) responsible for the conduction of water with minerals. Indexes of crown transpiration productivity analysed in the study seem to reflect reliably relations found in the forest phytocenoses and are confirmed in physiological dependencies between the transpiration apparatus, the vascular zone and tree height determined by the occupied social class in the forest community. It may be assumed that sapwood area (physiologically active) is characterised by the variable hydraulic conductivity, probably being the function of age and specific individual characters. In order to maintain the flow of transpiration, optimal for growth conditions, a tree as every living organism exhibits a certain adaptation ability, which makes it possible to meet the above conditions and cope with competition in the community.

Hydrochemical research conducted in the years 2007–2010 comprised monitoring of the Włosanka stream waters and leachate waters from the municipal landfill in Kulerzów in the Malopolskie province. 16 leachate samples were collected from the container taking into consideration the vertical stratification of the quality and samples of water from the Włosanka stream in measurement points situated before and after the landfill. Concentrations of metals: calcium, magnesium, sodium, potassium, iron, manganese and heavy metals: chromium, zinc, copper, cadmium, nickel and lead were determined in the leachates and the stream water. Analysis of the studied metals in the leachates revealed that only potassium concentration exceeded the highest admissible value which is the condition of introducing sewage to water bodies or to soil. Water along the investigated reach of the Włosanka stream, both above and below the municipal landfill was of quality class 1. The landfill had no significant effect on the studied metal concentrations in the stream water – no statistically significant differences were registered between the concentrations of the studied metals (including heavy metals) either in the point above or below the landfill. However, statistical tests comparing values of metal concentrations in the landfill leachates with the stream water revealed that the concentrations of 7 out of 12 tested metals were significantly higher in the leachates. Therefore, the landfill site monitoring should be continued, leachate waters should be collected in the container and supplied to the sewage treatment plant to prevent any threat to human life and health, or to the environment.

Opis:
the purpose of this paper was to review literature covering the topic of site index with particular emphasis on Scots pine, the most important forest-forming species in poland. we discuss the history of the site index, research on various tree species, statistical modelling methods, the spatial application of site index and age impact assessment. the history of research on the site index of forest species is long and dates back to the 18th century. Many researchers thought that determining the quality of the habitat is very important from the point of view of rational forest management. the site index, as a measure of the potential of the habitat on which the forest grows, is one of the most important characteristics of forest stands. the site index depends on the selected model, but is most often expressed as the average or top height of trees of a given species at a certain age. In our review, we point out several insufficiencies of studies on the site index, external influences and the connection of the site index with spatial conditions. Furthermore, research conducted so far has not explicitly confirmed that there is a relationship between the site index of pine stands and their geographical location in poland. More research on the site index, especially in regard with climate change, is needed.
