Nitrates are ubiquitous in the environment and key intermediates of various biochemical reactions in the nitrogen cycle, along with nitrites. A considerable source of nitrates is drinking water. There is substantial disagreement among scientists over the current limits for nitrate concentration in...

In order to investigate the main pollution factors of underground drinking water sources in semi-arid agricultural areas in China, and to reveal the threatening influence of pollutants on the normal water security of local society. Single-factor evaluation index, principal component analysis, basic...

Sediment is a source and sink of heavy metal contaminants in wetlands. In this study, sulfate-reducing bacteria (SRB) were used for the bioremediation of sediments from wetlands affected by acid mine drainage. The sediments were inoculated with SRB to study their influence on both the solution and...

Using a baffle reactor to degrade nitrophenol wastewater, with p-nitrophenol as the target pollutant, investigate the effects of nitrophenol concentration, external carbon source concentration, hydraulic retention time, and dissolved oxygen changes on the degradation of p-nitrophenol in the micro...

This study investigated the removal of methylene blue (MB) via adsorption using waste bottom ash. The bottom ash, sourced from a waste storage site in the Çorlu district of Tekirdağ province, Thrace Region, was utilized as the adsorbent. The research examined the impact of several variables on MB...

This study aimed to determine the extent of the water quality decrease in the Noyyal River in Tamilnadu by analyzing the seasonal change of water's physicochemical properties, identifying possible sources of pollution, and grouping the monitoring months based on shared characteristics. The...

This paper provides an overview of heavy metal removal technologies for wastewater treatment, with a focus on adsorption, chemical oxidation, ion exchange, and various coagulation processes. The discussion revolves around wastewater characterization as an essential first step in creating efficient...

Microplastics pollution poses a significant threat to aquatic ecosystems globally, originating from various sources such as plastic debris breakdown and microbeads. This study investigates the ecotoxicological impacts of these pollutants on marine plants and evaluates mitigation strategies. Field...

This research is conducted on Erbil basin, it is located in northern part of Iraq, the basin is composed of three main sub-basins which are: Northern part (Kapran), Central sub-basin and Southern part (Bashtepa) respectively. The total area of three sub-basins are approximately (3,200 km2). The main...

A novel technique involving hydrothermal synthesis was employed to prepare nanocomposite precursors of lamellar double hydroxide based basic mixed oxides. This method extended ongoing research on iron-impregnated hydrotalcite-supported nanomaterials. The iron-based Fe/MgAl-h nanocomposite was...
