This manuscript first gives a separate decomposition analysis on the factors that affect regional energy efficiency in Beijing, Tianjin, and Hebei, China, during 2005-12 based on the logarithmic mean divisia index (LMDI) model, and then makes an in-depth investigation on impact factors in the Beijing-Tianjin-Hebei (BTH) region of China. Energy efficiency is decomposed into carbon productivity, carbon...
The present study collected bacterial samples from water and bottom sediments from fish farms located in a nature reserve area in Poland with no recorded history of antibiotic use. The aim of the study was to determine the initial states of tetracycline, streptomycin, and erythromycin resistance before a potential increase of intensive aquaculture and application of antimicrobial agents in that region...
Over the years surface water quality of Pakistani rivers has been degraded. The current study aims to investigate the water quality and fish diversity at Rasul Barrage in the Jhelum River. A total of six sampling sites were assessed for pollution levels and fish fauna of the Barrage. Physicochemical parameters such as turbidity, biological oxygen demand (BOD), and chemical oxygen demand (COD) were...
Excessive human disturbance (e.g., overgrazing, deforestation) has degraded the environment in the Qilian Mountains in China. Vegetative restoration is likely to be a crucial tool to restore these biologically significant habitats, but it is impossible to achieve this goal if the baseline plant community composition and its variation with local environmental conditions were not understood fully. To...
For this paper we studied changes in areas of four land use variables were in the Małopolska Voivodeship of Poland. The following annual land use time series were used: surface area of agricultural lands, surface area of forest lands and wooded and bushy areas, surface area of built-up and urbanized lands, and surface area of wasteland. The autocorrelation structure and the temporal changes were studied...
The aim of this study was to evaluate the impact of a sewage treatment plant on the occurrence of gastrointestinal symptoms among the local residents. A survey was conducted on two populations: one from the vicinity of the sewage treatment plant (the exposed group: 586 people), and the other from outside the impact area of the plant (the control group: 502 people). The research area was divided into...
In this paper we report the behavioral responses of mated Tribolium confusum to blends of volatiles using a Y-tube olfactometer. Four doses of volatiles (1 ng. min⁻¹, 10 ng. min⁻¹, 100 ng. min⁻¹, and 1,000 ng. min⁻¹ in 50 μl of hexane applied on filter paper) were tested. A Y-tube experiment revealed that both mated females and males of Tribolium confusum were attracted to blends 4 and 5 at concentrations...
Complex analysis of thermal and gaseous states of chosen coal dumps performed by the authors made it possible to initially evaluate risk of spontaneous combustion of these objects and their classification based on indicators of a certain risk group. Thanks to the observation of coal dumps using a thermovisual camera, non-contact visualization of temperature distribution of the coal dump was obtained...
We investigated the effects of different concentrations of NaCl (25, 50, 100, and 150 mM NaCl) on growth, phenolic content, and antioxidant activities of horehound (Marrubium vulgare L.). The long-term salt treatment (up to 100 mM NaCl) resulted in significant (p<0.05) reduction of height, fresh weight, total chlorophyll, and total phenol contents. The negative effect of NaCl was accompanied by...
Surficial sediments and water (27 samples each) were collected from three representative lakes collapsed by mining activities in Huaibei, China. Contents of heavy metals (Sb, As, Cd, Pb, Zn) in both water and sediments were detected via atomic absorption spectrophotometry and atomic fluorescence spectrometry, respectively. The variation coefficient (C.V.) of each heavy metal as well as the partition...
This paper presents the results of 11 years study of aquatic warblers in the Roskosz Nature Reserve in eastern Poland. The study was carried out in fen mires near Chełm, in the proximity of the Polish-Ukrainian boundary. The number of aquatic warblers was correlated with the mean water level and with the mean groundwater level. We found that the higher the surface water level, the smaller the number...
Green roofs are becoming increasingly common practice of the urban sustainable environment. The growing substrate is the most important part of green-roof technology. The cost of engineering substrates can be reduced by using locally available components. Since green roofs are a relatively new concept in Poland, there is a need to examine substrate compositions and characteristics, including commonly...
Northern Chilean Patagonia has numerous pristine lakes associated with Nothofagus and Araucaria araucana forests. The present study consists of a study of optical properties in visible, close, and medium infrared wavelengths in mountain lakes surrounding Llaima Volcano – lakes that have associated Nothofagus and Araucaria araucana native forests with volcanic origins. The results revealed high reflectance...
Reducing greenhouse gas emissions and governing pollutant emissions would cause real synergy. Therefore, China has proposed achieving the target of reducing fine particulate matter (PM₂.₅) concentrations to 35 ug/m3 , as it pollutes the most. The prioritized purpose of this dissertation is aimed at constructing a comprehensive framework by integrating the PM₂.₅ target, influencing factors, and countermeasures...
Cadmium (Cd) is regarded as one of the most toxic environmental pollutants. A better understanding of the growth response, uptake, and translocation of Cd in barnyard grass (Echinochloa crus-galli) would be helpful for evaluating the role of this grass species as a potential candidate to be used for phytoremediation. The studied plants were grown in treated soils with increasing doses of Cd (0, 0...
Five soils differently contaminated by emissions from copper smelters were treated with the organic materials lignite, compost, and sewage sludge. The concentrations of Cu, Zn, and Pb in soil solutions were measured after different incubation times within 30 days. Speciation of metals in soil solution was determined via modeling with Visual MinteQ. Soil amendment with all organic materials led to...
Tree bark has been proven to be a valuable source of information on air pollution. Bark has a large absorbent surface thanks to its deeply furrowed structure. Through the ability to accumulate atmospheric particulate matter (PM), tree bark enables the identification and mapping of organic and inorganic air pollutants. The first study of air quality using tree bark dates back to the second half of...
Streamflow depends directly on climate conditions (e.g., precipitation and potential evapotranspiration, or Ep), which affect water balance at the basin scale. The present study was conducted to investigate the impact of climate change on streamflow in the Luan River basin, China. To assess the impact of climatic variation on streamflow, the temporal trends of streamflow were explored using the Mann-Kendall...
The main aim of this research was to analyse the impact of embankment construction on floodplain land use through a land use comparison of embanked and unembanked floodplains. Another purpose of was to assess the influence of studied floodplain land use on the environment. The analysis was conducted on the example of two cities along the Odra River in Poland: Oława and Brzeg, which significantly vary...
Based on Landsat 8-OLI (operational land imager) images and field surveys, we mapped soil salinization across seven ecosystems in the Manas River basin (MRB), and two models of soil salinization (namely an index model and a sensitivity model) were constructed on a regional scale and on the scale of a unit. ArcGIS ordinary Kriging interpolation was used to determine the spatial distribution of the...
