This paper presents the change detection analysis of two multispectral datasets for the Bostanlik District of Tashkent, Uzbekistan, using Landsat-5 TM data for 1989 and Landsat-8 OLI for 2017. Both supervised classification and maximum likelihood algorithms were utilized for the change detection analysis. Six land use classes were identified: snow cover, bare soil/rock, forest, waterbody, built-up...
Phosphorus is present in soil in various forms, including as insoluble organic compounds. Many species of soil-dwelling microorganisms release phosphorus from compounds that are sparingly soluble and make it partially available to crop plants. This group of microorganisms includes phosphate-solubilizing bacteria (PSB) that release phosphorus from relatively insoluble forms by producing organic acids,...
In order to study the sources and concentrations of heavy metals in atmospheric PM₁₀, a total of 144 samples were collected in two areas of Handan, China. The metal contents of Mn, Co, Ni, Cu, Cd, and Pb in the sample were analysed by inductively coupled plasma mass spectrometry. Contamination characteristics and sources were analysed by the geo-accumulation index and the enrichment factor method...
In recent years, with the rapid economic development of Bohai Economic bay area in China, the atmospheric environmental pollution problem has been of wide concern and has attracted great public attention. In this paper, the data of PM₁₀, SO₂, CO, NO₂, O₃ and PM₂.₅ in 12 cities located around the Bohai Bay area of China were collected in 2016. These 12 cities were divided into coastal and non-coastal...
The Beijing-Tianjin-Hebei Region (BTH) as a national strategic highland attracts attention with its haze problem. In particular, Hebei is a major emitter of carbon emissions in BTH. The establishment of the Xiong’an New District in Hebei, known as the “Millennium plan,” faces complex and diverse development in the future, so the carbon emission prediction and influence mechanism are of great significance...
The study includes an assessment of groundwater quality from one shallow and two deeper aquifers in the Danube left bank, under the conditions of coexistence of the open coal mine, arable lands with increasing irrigation needs and potential regional water supply system for the Banat region. The spatial distribution maps of the targeted parameters were used as a starting point in the identification...
A novel method was proposed for identifying air quality in China. Causality analysis-based significance tests combined with different machine-learning algorithms were carried out to achieve an automated and accurate classification. To this end, the most developed 100 cities in China were selected as study areas. We analyzed meteorological factors such as temperature, humidity, precipitation, wind...
Göksu Delta is an important wetland area in Turkey and has been declared a first-degree site and has been included in the Ramsar list. Agricultural activities continue for 12 months of the year due to the favorable climate in the delta and these activities are the most important income source for the people living in the region. Investigations to date have identified the presence of nitrogen pollutants...
Sheep manure was used to prepare biochar under pyrolysis temperature of 600ºC. The structural features of biochar were characterized by elemental analysis, BET analysis and scanning electron microscopy. The effects of pH, biochar dosage, adsorption time, temperature on adsorption of methyl orange (MO) in water by sheep manure biochar, as well as its adsorption mechanism, were investigated via batch...
Understanding drivers for energy consumption is important for economic and environmentally sustainable development. To explore this issue, the SDA (structural decomposition analysis) method based on input-output theory was used to analyze the influencing mechanism of energy consumption in one of the top energy consumers, Guangdong Province in China, during 2002 to 2012. We divided the process into...
Contemporary energy-saving mechanical ventilation systems combined with Earth-Air Heat Exchangers (EAHE) can reach high energetic and economic efficiency. The necessary condition for optimisation of ventilation system functioning is the adequate design of EAHE. This requires knowledge of soil temperature distribution in the location of EAHE. It constitutes a complex problem because of the influence...
Anaerobic membrane systems have been frequently applied for the removal of pollutants from wastewater. Membrane fouling is a challenging issue that decreases membrane life-span and increases costs. Anaerobic fluidized membrane bioreactor (AFMBR) is an emerging technology and many studies have shown its outstanding treatment efficiency and fouling mitigation performance. In this paper, wastewater treatment...
Nitrogen fertilization of agricultural crops increases nitrous oxide (N₂O) emissions from soils. The data used in this study were obtained from a long-term field experiment for corn, winter wheat and rapeseed cultivated on loam and sandy loam soils, and fertilized with the recommended nitrogen doses (kg N ha1 ) of 150, 120 and 150, respectively. The purpose of the study was to determine the relationship...
Contaminated wastewater discharged from tanneries in Pakistan creates a lot of pollution problems. This study presents the treatment of wastewater samples collected from inlet and outlet sections of Kasur Tannery Waste Management Agency (KTWMA) in Kasur, Pakistan. The procedure utilizes hydrogen peroxide (H₂O₂) in the presence of ultraviolet (UV) radiation for the successful degradation of pollutants...
Archaea communities widely exist in mangrove forest sediments, but their spatial variations among different distribution areas with salinity gradient in mangrove forest sediments is not well understood. This study used 16S rRNA Miseq sequence to investigate the sediment archaeal community structure and diversity of Bruguiera gymnoihiza mangrove forest in China along three different distribution areas...
Our paper deals with the solution of ecological flood-type accidents and the mitigation of their impacts during their occurrence. The main task is to defeat an accident on a watercourse as soon as possible, efficiently and economically, by arranging a floating boom. Closer specifications of the paper involve the technical use of floating booms and the calculation of the resistance force, which influences...
Rising environmental concerns toward the use of synthetic chemicals as well as global acceptance of natural products has emphasized the need for exploring novel and sustainable sources of eco-friendly dyes for the textile sector. Our study was conducted to explore the natural colorant potential of black carrot (Daucus carota L.) plant residue for textile processing and optimizing conditions for cotton...
This study attempted to develop statistical regression models for predicting the settleability of activated sludge based on the quality of incoming sewage and on the identified dominant filamentous species. As part of the analyses conducted for the purpose, classification models are presented that enable identification of the respective filamentous microorganisms, based on the working parameters of...
The developed eastern coastal cities of China are leaders of the national economy, which is growing rapidly. However, with this growth has come substantial misuse of resources causing significant environmental damage, including some 85% of global greenhouse gases resulting from the impact of economic development. To explore a reasonable approach to coordinated development of economic growth and the...
Plant hormones are trace organic molecules that play important roles in plant growth, development and stress resistance. 24-epibrassinolide (Br24) and strigolactones (Gr24) were reported to alleviate the toxicity of heavy metals and restrict their translocation into plants. In this study, the effects of Br24 and Gr24 with or without iron plaque (IP) induction on the uptake and accumulation of cadmium...
