Fly ash, solid waste from coal-fired power plant, had been utilized as raw material for porous geopolymer by alkaline activation and addition of hydrogen peroxide (H2O2) blowing agent. Porous geopolymer had higher surface area and total pore volume compared to fly ash and geopolymer without blowing...

A series of flow-cell experiments were performed to investigate the performance of cosmetic rhamnolipid surfactant flooding on the relationship between source zone mass removal and mass flux reduction for pool-dominated DNAPL TCE source zones in heterogeneous porous media. The results were also...

Contamination of groundwater by chlorinated solvents such as trichloroethylene (TCE, tetrachloroethylene (PCE), and 1,1-dichloroethylene (1,1DCE) is a widespread problem that can seriously threaten human health and the environment. These compounds are often present as dense nonaqueous phase liquid...

Transportation driven by fossil fuels increases air pollution induced by urbanisation. Heavy metals such as Cadmium (Cd), Chromium (Cr), Copper (Cu), Iron (Fe), Lead (Pb), and Zinc (Zn) are life-threatening elements and their concentration is increasing alarmingly in soil in various countries. Air...

The Yellow River Basin is an important economic zone in China and an important base for energy, chemical, raw materials and basic industries. However, the sloppy development pattern of "high consumption and high pollution" in nine provinces along the Yellow River Basin has become an important...

Excessive use of fossil fuels results in the rapid depletion of non-renewable fossil energy resources, a rise in fuel cost, and an uncontrolled emission of greenhouse gases which causes a severe threat to the environment. Bio-fuels are being scrutinized as substitutes for current high-pollutant...

BTEX, also known as benzene, toluene, ethyl benzene, and xylene, is a common gasoline oxygenate. The contamination of groundwater and surface water with BTEX and its primary breakdown product has drawn a lot of attention. However, surface-modified zeolite's sorption mechanisms and affinity for BTEX...

Waste generated as a result of the leather processing industry can be in the form of solid, liquid and gas waste. Waste generated from the textile industry made from clothing H2S and TSS which if not treated properly, will be very dangerous for health and the environment. One of the efforts to...

The current study work's contribution relates to the removal of xylene using an adsorbent with modified surfaces made from a naturally occurring substance called avocado seed. With the aid of a muffle furnace heated to 600⁰c, this was converted to become activated carbon. Activated carbon is...

The pollution and toxicological effects of microplastics in soil have gradually attracted widespread attention, but studies on the ecological effects of microplastics on soil microorganisms and their mechanisms are still very scarce. To explore the physiological response of ectomycorrhizal fungi...

Nowadays, due to the development of the world, harmful gases and vapours have begun to enter the atmosphere significantly, so we are faced with the problem of air pollution and its low quality. This paper, therefore, focused on enclosed car parks, a parking system that needs to be well examined from...

In this study, activated sugar beet pulp as a biosorbent was used to remove Red-254 dye from aqueous solutions. The contact time, pH, biosorbent dosage and temperature were chosen as the parameters affecting the biosorption process. In the experiments, the batch adsorption technique was used. The...

In terms of sustainable land use management, it is extremely important to reveal the land conditions and the changes that occur on the land in certain periods. In this study, using CORINE data for Düzce province, land use status and transitions between land-use classes over 28 years were...

Ramsar sites are important ecosystems that are protected by international status, have great value in terms of biodiversity, and constitute a resource in terms of economic, cultural, scientific and recreational aspects. In this study, the change of Lake Uluabat Ramsar Site and its surroundings...

Due to the development of open access medium-high resolution remote sensing data like multispectral remote sensing images, crop classification becomes a hot research topic to be realized on large scale using machine learning (ML) models. At the same time, chlorophyll content is a critical index used...

A technique for green manufacturing of zinc oxide based nanoparticles utilising cassava peel has been approached in this research for antibacterial investigation. Especially, the cassava peel is an agro waste from starch and food processing industries and the extract of Cassava peel is used for...

Photocatalytic degradation for wastewater treatment is a method that has recently attracted attention. In this research, a synthesized composite of Fe3O4/SiO2/NiO with magnetic properties was used for the photocatalytic degradation of methylene blue dye under UV light. Furthermore, the composites...

The dumping of solid waste in uncontrolled landfills can cause significant impacts on the environment and human health. The open dumps cause the formation of leachate which contaminated the groundwater; use of these groundwater reported danger to the human health. The goal of groundwater protection...

The locally available tamarind fruit shells (TFS) pre-treated with 1N H3PO4 was used to remove the hexavalent chromium (Cr6+) from aqueous phase. The investigation was done by using continuously mixed batch reactor (CMBR) under room temperature. Few preliminary investigations was undertaken to...

Water famine is very cruel. The desalination plant was brought in to alleviate the water shortage. A desalination plant has been set up in many places around the world. In the view of expanding worldwide need of fresh water, the usage of desalination plant becomes more common. There are more than...

Trees in the forest are an unprecedented cluster of organisms in ecological, monetary and social importance. With a wide distribution, mostly random spread over and a large population in terms of size, the majority of tree species show considerable variation in genetics both within and between...

In order to explore an effective assessment method for the treatment effect of heavy metal pollution in the sediment of Taihu Lake in China, based on the research background analysis and literature review, this paper reconstructs the spatial niche suitability model and applies it to the effect...

This research describes the bacteriological and physicochemical impact of two types of irrigation water on soil and turfgrass quality during 2018 and 2019. Wastewater treated by an activated sludge process coupled with UV disinfection UV-TW was compared to fresh water FW. The first cycle (2018) was...
