Mercury (Hg) is an environmentally hazardous metal and pollutant in key European legislation pertaining to the marine environment (the Water Framework Directive WFD and the Marine Strategy Framework Directive - MSFD). Despite the environmental importance of Hg there is limited knowledge on levels in...

An economy's progress is critically dependent on industrialization. However, it also negatively impacts the ecosystem by releasing dangerous elements like heavy metals into surface aquifers. The purpose of this study was to assess the contamination by heavy metals of edible plants (pepper...

The objective of this work is the treatment and purification of an aqueous solution loaded with a mixture of dyes, malachite green (MG) and rhodamine B (Rh-B) using a green emulsified membrane GELM. The proposed GELM process consists of a surfactant (Span 80), an internal phase (sulfuric acid) and a...

Perfluorooctanoic acid is ubiquitous in wastewater, bioaccumulative and biotoxic, and interferes with biological wastewater treatment. Extracellular polymeric substances are important components of microbial cells. The effects of perfluorooctanoic acid (0 mg L -1, 0.1 mg L -1, 0.5 mg L -1, 1.0 mg L...

This study employed a simple hydrothermal (HT) approach to synthesize vanadium pentoxide (V 2O 5) nanomaterials. The inherent limitations of V 2O 5, including low quantum efficiency and insufficient light sensitivity, restrict its potential for enhanced photocatalytic activity. The study...

Bottled water is considered a safe water source and extensively consumed worldwide. However, increased health concerns about its contamination by organic pollutants and polymeric micro/nonfibrous particulates have arisen in the last few years. Therefore, this work is designed to screen the bottled...

Polycyclic aromatic hydrocarbons (PAHs) are toxic and ubiquitous in the water environment. The content of PAHs needs to be systematically and comprehensively detected to achieve the environmental quality assessment. However, due to the constraint of testing cost, detection data in the Songhua river...

This article represents the photocatalytic activity of harmful pollutants from textile and pharmaceutical industries and compares the photocatalytic efficiency between pure MgO and MgO – SiO 2 nanocomposite. The MgO NPs are synthesized using hydrothermal synthesis, in which the extract from Nerium...

To assess the efficacy of removing heavy metals such as Cu (II) and Ni (II) ions from aqueous solution, the adsorption behaviour of a nanocomposite powder comprising of reduced Graphene Oxide (rGO), bentonite clay, and ZnO was investigated. Various analytical techniques including Fourier transform...

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...
