The objective of our study was to determine changes in protein and monosaccharide content in select grass species due to an application of the kelp species Ecklonia maxima extract. The field experiment was arranged as a randomized sub-block design (split-split-plot) with three replicates. The following factors were examined: growth stimulant with the trade name Kelpak SL, which was either applied...
The article tries to find the best solution of the system, which aims to dispose of the waste stream, being at the same time an economically justified and socially acceptable system. In order to find the best possible system three strategies for dealing with waste were considered, evaluated by 11 criteria in line with sustainable development, included in the following groups: environmental, social,...
A semi-field test was conducted to assess the risk of exposure to fufenozide in a ditch and pond adjacent to an agricultural area. To support the investigation, a fast, highly selective, and sensitive method was developed to determine the residue of fufenozide in water, sediment, and soil through high performance liquid chromatography- tandem mass spectrometry. The recoveries were in the acceptable...
One of the most interesting though little-known water ecosystems of Łęczyńsko-Włodawskie Lakeland is its small water bodies – ponds and wetland reservoirs. Three ponds and three wetland reservoirs were studied in 2008 and then again in 2012 and 2013 to examine their rotifer assemblages. While watching the changes occurring in the plankton during periods of 4 and 5 years, we were trying to find out...
A new hybrid inorganic-organic copolymer, aluminum chloride-poly(acrylamide-co-acrylic acid), was prepared using the free radical polymerization method and employed in this study. The hybrid copolymer was characterized by Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), and energy-dispersive x-ray spectroscopy (EDS). This hybrid copolymer was used in the flocculation...
This paper proposes a metafrontier non-radial and non-oriental DEA to examine environmental efficiency in China. This approach takes the regional technology heterogeneity, non-radial slacks, and undesirable outputs into consideration simultaneously. The results show that undesirable output inefficiency largely contributes to environmental inefficiency. And under the metafrontier technology assumption,...
The aim of this study was to analyze the influence of brewing time on the content of select trace elements (Cu, Zn, Fe, Mn) and heavy metals (Pb, Cd) in homogeneous and mixed herbs used in therapy of digestive system diseases and in regulation of digestive processes. The study involved 10 types of preparations of herbal teas (mono- and multi-component sachets) acting on the gastrointestinal tract...
This paper uses GIS to describe and evaluate forest fire risk considering the most important factors affecting fire behavior at fine scales. The study was implemented in Yeşilova Forestry Enterprise in the Mediterranean city of Kahramanmaraş, Turkey. To determine an overall fire risk index for the study area, fire risk rating (extreme, high, moderate, or low) was assigned to decision variables (i...
This article describes the changes in the land cover and management of floodplains in towns located on Poland’s Oder River, estimates flood risk and how it has been changing in these towns, and how these changes have affected the environment. The paper also includes an analysis of trends in floodplain management defined in local planning documents. The research was conducted for the period of 1995-2010...
Our article investigates the response of the synthetic unit hydrographs (SUH) to parameter changes using sensitivity analysis. The beta and Weibull probability density functions and the objective function that includes both the peak discharge and time to peak were chosen to construct the SUHs for a small mountain catchment. The absolute and relative dependences between the distribution parameter changes...
Seismic waves travel faster in rock stratum and have greater environmental responses. This paper analyzed the transmission regulation, vibration frequency, and amplitude attenuation characteristics of waves in layered elastic medium. Also, impacts of the elastic modulus of homogeneous medium, subway tunnel depth, and other factors on the environmental response in the runtime were investigated. Based...
This paper presents results of research on the use of plasma technology for printed circuit boards (PCB) processing for metals and energy recovery. In the Industrial Research Institute for Automation and Measurements, a test stand was built allowing experiments on plasma process with throughput of 800 kg per day. Brief examination of PCB waste was carried out, focusing on identification of its heating...
The production of sewage sludge has been sharply increasing by municipal sludge treatment plants in China. Sewage sludge is a difficult waste to manage not only due to the high quantities produced but also due to its high concentration of heavy metals and pathogens. The pyrolytic conversion of sewage sludge to biochar and then applied to the land is a sustainable management potion. Therefore, the...
Systemic vulnerability is an internal and essential factor that influences environmental sustainable development capability. Optimizing adjustments on systemic vulnerability significantly contributes to improved function, decreased disturbance, and guaranteed scientific evolution of environmental sustainable development capability. The connotation of systemic vulnerability of environmental sustainable...
Pharmaceuticals have become an emerging environmental protection problem due to their presence in water and soil ecosystems. Reliable cell viability biomarkers (mitochondrial and cytosol distribution of cytochrome c oxidase activity), germination, and growth of seedlings were assessed to be sensitive endpoints of diclofenac toxicity. Moreover, the content of soluble carbohydrates in seedlings of three...
This study was undertaken in order to determine the effects of the constant magnetic field (CMF) on the effectiveness of dairy wastewater treatment under anaerobic conditions. It demonstrated that increasing the value of the magnetic flux in the analyzed range resulted in an increasing effectiveness of the fermentation process. Magnets with induction of 0.38 [T] elicited significant changes in the...
The metamorphosis from land cover to land use for urban, industrial, and other socio-economic developments in Kuwait has remarkably evolved the “coastal morphological landscape (CML)” such that the impact has decreased carrying capacity. Information on carrying capacity is vital for decision makers to take immediate steps in preserving the coast. Mitigation and control measures are essentially required...
This study investigated the influence of anthropogenic salinization on planktonic rotifer communities and traced changes in their diversity along a salinity gradient. The experiment was conducted in 14 ponds of varied anthropogenic origin located in Poland’s Silesian Upland. On the basis of the mean concentration of total dissolved solids (TDS) and principal component analysis (PCA), the water bodies...
This paper describes the response of fungi as well as β-glucosidase and arylsulfatase to soil contamination with the herbicides Alister Grande 190 OD, Fuego 500 SC, and Lumax 537.5 SE in the following doses: 1 – recommended dose, and doses 20-, 40-, 80-, and 160-fold higher than the recommended one. A laboratory experiment in three replicates was conducted on sandy loam of the pHKCl – 7.0. The results...
Our study investigated the effects of dietary supplementation with zinc and polyphenol compounds, i.e. resveratrol and genistein, on the effectiveness of changes in the content of select elements (Zn, Mg, Fe, Ca, and P) in hair of rats with chemically (DMBA (7,12-dimethyl-1,2- benz[a]anthracene) induced mammary cancer. Regardless of the diet (standard; Zn; Zn+genistein) there occurred an increase...
