Suspended sediments load estimation in the Indus River and its important tributaries in Khyber Pakhtunkhwa, Pakistan is presented to determine siltation in major reservoirs in the area and to create a strategy to minimize and/or control this risk for the enhancement of hydel energy production, irrigation, and other domestic purposes. The study area is part of an orogenically active region along the...
The aim of our study was to identify the methanotrophic group of bacteria inhabiting coal mine rocks at the Jastrzębie-Moszczenica (Jas-Mos) coal mine, by application of molecular techniques: polymerase chain reaction (PCR) and fluorescence in situ hybridization (FISH). In the first stage of the experiment, methanotrophic activity (AM) of the rock material at different temperatures (20 and 30ºC) and...
The content of nutrients and heavy metals was indicated in different parts of Typha angustifolia and Typha latifolia, collected in lakes in western Poland. Three groups of metals were indicated, depending on the place of their accumulation. The cattail species studied differed significantly with their Cu, Pb, and Cd content, but were characterized by the same accumulation pattern in the leaves: Mn...
Iron oxides are a group of minerals composed of Fe together with O and/or OH. They have high points of zero charge, making them positively charged over most soil pH ranges. Iron oxides also have relatively high surface areas and a high density of surface functional groups for ligand exchange reactions. In recent time, many studies have been undertaken on the use of iron oxides to remove harmful oxyanions...
Pulverized coal boilers, commonly used in the power and heat-generating industries, constitute one of the most important sources of fine particulate matter (PM) emitted to ambient air. The evidence on airborne PM and its public health impact is consistent in showing adverse health effects at exposures currently experienced by urban populations in both developed and developing countries [1]. The amount,...
The total content and available forms of trace metals (Cd, Cr, Cu, Ni, Pb, Zn) in fluvial sediments has been determined for surface samples (0-30 cm) collected in 2009 and after the flood in 2010 from the flood plain of the Odra River in western Poland. Total metal concentrations were obtained after mineralization with HNO₃, and the available forms of trace metals were obtained by single extraction...
The effects of short-term (30 s) exposure of amaranth seeds to low frequency magnetic field (f=50 Hz, B=30 mT), laser light radiation (λ = 632.8 nm), or to their combination on germination, plant height, and the content of photosynthetic pigments were examined. The conducted experiment consisted of three independent parts: 1 – laboratory experiment where seed germination was carried out on Petri dishes...
Forest soil together with the mulch covering it, its chemical composition, oxygen conditions, pH, moisture, and food resources determine the specific species composition of edaphon. The aim of this study was to evaluate the effects of acidic runoff off the bark of a tree on the faunistic list of macro-pedofauna at different distances from the base of the trunk. The study was conducted in the central...
In our work a two-stage A/O system consisting of two independent A/O subsystems was used to remove high concentrations of COD, nitrogen, and toxic matter from mixed wastewater discharged by a comprehensive chemical group. The mixed liquid return was not adopted, and the sludge return ratio was kept at a high value of 100-200% to maintain high usable activated sludge concentration. Adequate NaHCO₃...
The purpose of this study was to determine the effects of soil compaction on the chemical properties of soil and herbage yield of lucerne (Medicago sativa L.). A field experiment was conducted on a silty loam Mollic Fluvisols soil in 2003-07. Four compaction treatments were applied three times annually by tractor using the following number of passes: control without experimental traffic, two passes,...
Hydrochemcial research conducted from January 2007 to December 2010, and microbiological analyses performed from January 2007 to December 2009 included 12 streams in three areas of Małopolska Province, in which construction of small water reservoirs has been planned. Water samples were collected from the streams in measurement-control points situated on the sites of planned dams. Stream water suitability...
The basidiomycete Volvariella bombycina (Pluteaceae) is included in red lists of fungi in Poland and some other countries. Its distribution in Poland is presented, based on published data as well as 12 new locations. Platanus × acerifolia is reported for the first time as a host of this fungus. Another six tree species are new hosts for V. bombycina in Poland. These new data confirm the high ecological...
This study presents the contribution of reclamation works to the disappearance of Lake Jelenino. On the basis of cartographic materials from the 19th and 20th centuries, as well as historical records, it was possible to establish that the lake of area 495.2 ha disappeared as a result of precise actions aimed at creating new settlements. Reclamation works proceeded in two stages. After the first stage,...
The aim of our study was to compare the efficacy of extraction of genotoxic pollutants from soils performed by means of several solvents. Soil pollutants were extracted in the Soxhlet apparatus. Extract genotoxicity was assessed using the Ames Test. All the examined soils (12) contained genotoxic pollutants. Extraction with hexane allowed detection of pollution genotoxicity in 11 soils, whereas with...
Internal surfaces of polymeric (PVC, PE, PP, and PB) pipes were assessed for potential colonization by microorganisms present in a water distribution system. Biofilms that had formed on the surfaces of particular polymer samples were examined by SEM microscopy and Koch's method. Surface damage caused by microbial activity was measured by contact profilometry. PP (1.5×10⁶ CFU/cm²) and PB (4.9×10⁵ CFU/cm²)...
This paper presents the effect of soil supplementation with urea and magnesium on nitrogen uptake and its utilization by two different types of hybrid maize cultivars. Based on the results of 3-year fertilization studies, it was shown that for average volume of grain yield of maize, nitrogen content in grain dry matter and nitrogen uptake with its yield was significantly determined by the doses of...
Little is known about soil thallium contamination near tungsten (W) mines. This study investigated thallium, arsenic, and mercury contents and enrichment in agricultural soils near the world’s largest and longestoperating W mine in China. Results show that the long-term W mining significantly elevated Tl from 0.77 to 1.61 mg·kg⁻¹ and As from 7.54 to 22.64 mg·kg⁻¹, with enrichment factors of 2.0 (1...
A greenhouse experiment was carried out to determine the effect of biotechnological and fungicide treatments on the colonization of winter wheat kernels by epiphytic and endophytic Pseudomonas and Azotobacter bacteria, filamentous, and yeast-like fungi. Microbiological analyses were performed using two techniques that involved placing kernels on PDA medium, and washing kernels to remove the microbes...
Our paper discusses a scenario for adapting residential buildings to the requirements of the EU climate and energy package. It analyzes the option of reducing pollutant emissions to ambient air by switching to alternative energy sources in a typical single-family residential building. The most common sources of energy in central heating and ventilation systems and water heating systems were compared,...
Our study focuses on the subject of planning spatial development of communes within the context of protecting and using ecosystems. For the purpose of this article, within the context of planning the future spatial development of the commune, the following areas have been chosen: ones within which the ecosystem provides terrain for the benefit of humans, ones that people use as open landscape (altering...
