As the production of biomass waste from agroindustry grows across the world, a large amount of agro-based ashes ends up in polluting land. India produced 405.4 million tones of sugarcane in 2019, with a capacity of 105.4 million tonnes of bagasse and 2.5 million tonnes of SBA. The utilization of...

The amount and type of waste are increasing due to population growth. Many harmful materials have been in the atmosphere for a very long times. This causes a crisis in the waste disposal and thereby contributes to environmental issues. Recycling concrete manufacturing waste materials not only offers...

In recent years there has been a heightened concentration on the industrial subsectors that are the primary contributors to environmental pollution. Filler materials made from mineral limestone, which is composed of calcium carbonate (CaCO3), are utilized in the production of polymer composites in...

The world is witnessing a boom-in construction industry due to urbanization which leads to over-exploitation of primary resource to match the demands and also increase the land pollution. The advent of nano engineering technology has a significant impact on cementitious materials, particularly...

A green synthesis using a simple precipitation method produced zinc oxide (ZnO), leaf extractions of zinc oxide as Aerva lanata (Al-ZnO) and Millettia pinnata (Mp-ZnO), copper-doped Al-CZnO and Mp-CZnO nanoparticles (NAPs). They were characterized for their functional group, structural...

Azo dye is a synthetic aromatic dye which are direct dye frequently used in textile industry to colour fibres. It also contributes to the damage of the environment. This study examines the adsorption biochar made from Annona reticulata to remove azo dye from textile wastewater. To improve the...

The aim of this study was to investigate the tensile strength reduction of four different materials: steel, polypropylene, polyethylene and glass fiber/epoxy (GFRP), under the conditions in a chemical scrubber. In detail, the performance of these materials in an acidic environment was assessed. The...

The microbial consortia incorporated in bio concrete should have traits such as high alkali resistance and the ability to form endospores to overcome the mechanical and chemical stresses produced during concrete preparation. The primary intent of our work is to segregate and identify the calcium...

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 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...

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...

The coconut shell-derived biochar was employed in this study to remediate Remazol Black B from aqueous solutions. For efficient dye remediation, preliminary batch investigations focused on adjusting temperature, biochar dosage, initial dye concentration, and pH. The results shown that dosage of...

Anthracene and phenanthrene belong to a group of persistent environmental contaminants called PAHs. Evaluation of the structure of two selected PAHs i.e. anthracene and phenanthrene on their resistance to destruction by UV-activated PDS was the aim of this study. The authors focused on two aspects...

This study analyses seasonal and regular variations in ambient atmospheric concentrations of total gaseous mercury (TGM), ancillary air pollutant concentrations, and their relationship to weather conditions of a megacity environment in India. Further, to correlate with TGM concentrations at...

Aiming at the problems of long monitoring time, low sensitivity and low precision of traditional methods, a nano sensor for near zero emission monitoring of sulfur hexafluoride (SF6) was proposed. The characteristics of SF6 gas were analyzed. The infrared spectrum of SF6 gas was obtained by spectral...

The degradation of Remazol Black (RBB) by S-TiO2 photocatalyst was investigated. X-ray diffraction, fourier-transform infrared spectroscopy, scanning electron microscopy, transmission electron microscopy, and UV-vis specular reflectance spectroscopy has been used to characterize S-TiO2. The results...

Volatile Organic Compounds (VOCs) are toxic for the environment and human health and their tendency to readily volatilize in the atmosphere can lead to problems connected to odours annoyance. Conventional VOCs gaseous emissions treatments entail the application of chemical-physical processes, only...

This paper analysis the contents and variation of heavy metals in wet and dry deposition in Changji (Xinjiang, China) revealed their reducing regularity for heavy metals in atmosphere in arid area. Samples (including 84 dry deposition samples and 16 wet deposition samples) were collected from...

Here the effectiveness of cation selective membranes, produced for divalent mercury (Hg2+) preconcetration from aqueous bodies, is examined. To this end, the behavior of PVC-based membranes, functionalized with dithizone for mercury complexation, is examined by means of Energy Dispersive X-ray...

Removal of Co(II) ions from aqueous solutions using chitosan-vanillin (polymer I) and chitosan-ortho-vanillin (polymer II) adsorbents has been investigated under different experimental conditions.
