This study was aimed at studying the effect of heavy metals and arsenic on the survival and biofilm formation of some saprotrophic microorganisms: Bacillus megaterium var. phosphaticum, Bacillus mucilaginosus, Pectobacterium carotovorum, and Escherichia coli. As a source of heavy metals and arsenic, we used aqueous solutions of NaAsO2, Cd(CH3COO)2,...

Magnetic graphene oxide (MGO) is an inorganic composite material composed of graphene oxide (GO) that has the characteristics of GO and magnetic material. The application of MGO in water treatment can effectively solve problems such as difficult recovery of the adsorbed GO from liquid, low efficiency, and high treatment cost, which are regarded as ...

Currently, plastic pollutants in the aquatic environment have received much attention. The studies on the abundance of microplastics in the river system are consequently lower compared to the studies on the marine system. The study aimed to determine the abundance of microplastics in water and riverbank sediments of Miri River and classify their sp...

In this study, alterations in behavior, oxidative stress, and related gene expressions, as well as histopathological changes in the brain, of zebrafish were evaluated following exposure to cadmium chloride and mercury chloride alone and in combination for 21 days. In the light–dark preference test, the time spent in the dark side and numbers of ent...

Biological nitrogen and phosphorus removal often requires an external carbon source to be effective during wastewater treatments. The purpose of this work was to evaluate a sequencing batch reactor (SBR) operated in a non-conventional anoxic/aerated (An/O) regime (alternated condition) treating synthetic wastewater simulating secondary anaerobic ef...

Inland waters potentially contain vast quantities of microplastics (MPs), being tropical ecosystems in developing countries possibly subjected to continuous and uncontrolled plastic waste disposal. This study reports on the intake of polyethylene terephthalate (PET) MPs by a small-sized tropical freshwater microcrustacean. We began by analyzing if ...

The transformation of poultry litter waste through the pyrolysis process produces a product called biochar which, applied to the soil, improves its characteristics. The objective of this work was to evaluate the effect of biochar produced from poultry litter wastes, submitted to pyrolysis at 350 °C on soil chemical and physical characteristics. For...

Zero-valent magnesium (ZVMg), glacial acetic acid (GAA), and vitamin B12 were used to degrade trichloroethylene (TCE) in either pure anhydrous ethanol (EtOH) or 10% anhydrous EtOH in canola oil. Gas chromatography–mass spectrometry (GC–MS) was used to monitor the decrease in TCE concentration within each system over time. In pure anhydrous EtOH, a ...

Electrokinetic remediation of groundwater pollutants uses electrical fields to draw contaminants towards electrodes, where they are removed through diverse mechanisms. Conventional electrodes are installed in discrete positions in the soil. Here, we develop unconventional electrodes for the electrokinetic remediation of Cr(VI). Our electrodes are f...

Remediation of contaminated soil and sediment is important for improving the eco-environmental quality. Electro-kinetic remediation (EKR) is an environmentally friendly technology to migrate and remove pollutants from the soil and sediment matrix. This paper analyses the mechanism and performance of EKR of heavy metals, organic pollutants, and comp...
