In addition to a production of animal feed, they have a positive impact on quality of soil. This study determined the suitability of selected stubble catch crops (white mustard, lacy phacelia, and a mixture of faba bean + spring vetch) to improve production, economic and energy effects of spring wheat grown in 3-year monoculture relative to the control treatment (without catch crops). Two tillage systems were used: conventional tillage and no-tillage (conservation tillage). A field study was conducted over the period 2014-2016 at the Czeslawice Experimental Farm, Lubelskie Voivodeship, Poland. The study proved the high suitability of catch crops to increase the spring wheat yields (under both tillage systems). Regardless of the catch crops, the productivity of wheat was higher under conventional tillage. The catch crops (in particular white mustard) and the conservation tillage system contributed to an impr...

The basis of these filtering materials includes fibrous ion exchangers with the complex immobilized on their functional groups. It has been established that the degree of catalytic hydrogen sulphide decomposition depends on the reaction time. Thus, the required degree of hydrogen sulphide removal from air could be easily controlled by applying appropriate thickness of the filtering layer under a given filtering velocity. It allows applying very thin filtering layers of the Fe(III)-EDTA/Fiban AK-22 or Fiban A-6 catalysts. The obtained results of the research confirm the applicability of these materials for deep air purification from hydrogen sulphide.

One of the main sources of methane emission is agriculture (rice cultivation and livestock raising). Limiting the cultivation of rice would not be sustainable, as it is the basic source of alimentation for a large share of human population. On the other hand, introducing feed additives which limit the methane production in rumens can be considered sustainable. Another significant source of methane emission are landfills. Utilizing this gas for energy purposes is the most sustainable solution. However, as only part of methane can be used as the source of energy, the natural process of methane oxidation by methanotrophic bacteria occurring in soil may contribute to sustainable reduction of its emissions from landfills.

It has been pointed out that the anthropogenic emission of CO2 amounts only to 3% of emissions from the natural sources. It has been also noted that increasing CO2 absorption of terrestrial ecosystems by 3% could inhibit the increase of CO2 concentration in the atmosphere. This means that mitigation of global warming by intensifying natural pro- cesses is a more sustainable solution than performing expensive changes in energy policy. Lowering the emission of methane, on the other hand, can be accomplished by utilizing fodder additives for ruminants and the process of microbiological methane oxidation in covering soil layers or biofilters.

Selected physicochemical parameters of waters were marked in the study. The water was collected from 19 wells located close to a shale gas extraction site. The water quality index was determined from the obtained parameters. A secondary objective of the study was to test the capacity of the artificial neural network (ANN) methods to model the water quality index in groundwater. The number of ANN input parameters was optimized and limited to seven, which was derived using a multiple regression model. Subsequently, using the stepwise regression method, models with ever fewer variables were tested. The best parameters were obtained for a network with five input neurons (electrical conductivity, pH as well as calcium, magnesium and sodium ions), in addition to five neurons in the hidden layer. The results showed that the use of the parameters is a convenient approach to mod...

The sequestration of carbon dioxide in the biomass of plants, especially the ones which can be cultivated as catch crops is described. It was shown that the cultivation of catch crops may play an important role in the mitigation of CO2 emissions.

The analyses of CO2 and CH4 fluxes in the environment showed that intensifying natural photosynthesis and respiration process may significantly contribute to the mitigation of greenhouse gases emission. It has been proven that the intensity of photosynthesis in land ecosystems could compensate for the increase of CO2 emission from anthropological sources.

Cluster analysis was employed for evaluation of the behaviour of chemical compounds in the water of piezometers from the drilling waste management facility in Luchów. Cluster analysis proved to be an efficient method, enabling the identification of groups of chemical compounds threatening the environment.

In the pages that follow, we will report the results of evaluation of the potential ecological risk and trend of soil heavy metal pollution surrounding the drilling waste deposition site in western Poland. The concentrations of heavy metals: Cd, Cr, Cu, Pb were determined by inductively coupled plasma optical emission spectrometry. The procedure used for potential ecological risk assessment was as proposed by Hakanson (1980). The calculated potential ecological risk factors come in the following order EiR(Cd)>EiR(Pb)>EiR(Cu)>EiR(Cr), which shows that Cd is the most important factor leading to risk. The uniform model was employed to determine the time in which Cd concentration will exceed the permissible concentration level, as regulated by Polish Law. The Pearson correlation coefficient was employed along with the correspondence analysis in order to determine the relationships between heav...

Throughout the period 2010-2015, 72 exploratory drillings were made (as of 4.01.2016), while hydraulic fracturing was carried out 25 times. Employing new drilling and shale gas prospecting technologies raises a question pertaining to their impact on the environment. The number of chemical compounds used (approximately 2000) for the production of new technological fluids may potentially pollute the environment. The fact that the composition of these fluids remains undisclosed hinders the assessment of their impact on the environment and devising optimal methods for managing this type of waste. The presented work indicates the chemical compounds which may infiltrate to groundwater, identified on the basis of technological fluids characteristics, as well as the review of studies pertaining to their impact on potable water carried out in the United States. The study focused on marking heavy metals, calcium, sodium, magnesium, potassium, chlorides and sulphates in the surface waters collected in proximity of Lewino well.

An analysis of selected parameters of deposited drilling waste, groundwater taken from piezometers and eluates obtained during batch leaching tests of drill cuttings was the basis for the estimation. The high concentrations of barium, lead, and zinc in drilling waste (maximum measured values equal to 54; 152; and 438 mg/kg dry weight, respectively) do not allow to classify the examined materials as inert waste from the extractive industries. The groundwater taken from the piezometers located around the drilling waste landfill contained high concentrations of total organic carbon (up to 21.9 mgC/L) boron, calcium, magnesium, manganese, aluminum, and potassium (up to 2.12; 455; 148; 1.75; 5.11; and 25 mg/L, respectively). In contrast to this observation, concentrations of barium and chlorides were the most exceeded in the batch leaching tests. It suggests that pollution of groundwater was not caused by drilling waste deposition.
