Catchment scale modelling of micro and emerging pollutants
… forces.Moreover, if the solutes are micro and emerging pollutants (i.e. pharmaceuticals), which are non-regulated contaminants not routinely monitored but often-detected in fresh waters, the description of the transport sources and routes becomes an interesting and challenging topic to …

High throughput analysis to study emerging pollutants and nanoparticle fate in biological systems
<p>”The increasing applications of emerging and fugitive contaminants (EFCs) and engineered nanoparticles (ENPs) attract significant research interest for their potential risks to human health and the environment. In order to assess the health risks of these emerging contaminants, rapid and …

Catalytic Ozonation of Emerging Pollutants in Water in the Presence of MCM-41 and Fe-MCM-41
… the removal of the representative organic pollutants (ibuprofen (IBU) and oxalic acid (OA)) in water in a catalytic ozonation process was investigated in this thesis. This study particularly addresses the preparation of modified catalysts, the role of pH and water matrices on the …

Analysis of antibiotics and PFAS as potential emerging pollutants in the water bodies and their accumulation in food samples
Antibiotics and perfluoroalkyl substances (PFAS) are groups of anthropogenic substances that are found in industries and consumer products, i.e., antibiotics are used in healthcare facilities, pharmaceutical companies, and agriculture, whereas PFAS are used in industries and households. These …

Fast reverse osmosis through nanotube-based membranes: molecular dynamics study
… produce high quality water by removing ions and emerging pollutants. In the first part, we investigate reverse-osmosis through commonly used polymeric and advanced inorganic nanotube based semi-permeable membranes by performing non-equilibrium molecular dynamics simulations. Simulations indicate …

Effects of Microbial Community Stress Response and Emerging Contaminants on Wastewater Treatment Plants
… on microorganisms in activated sludge to remove pollutants from wastewater and therefore an understanding of how these microorganisms are affected by various conditions and pollutants is needed. Also, as consumer products and industrial processes evolve, so do the pollutants they discharge to …

PHOTOACTIVE HYBRID GRAPHENE-BASED POLYMERIC MATERIALS FOR WATER PURIFICATION
The combined challenges of growing population, climate change and increasing lack of raw materials are leading to paramount innovation in the design of novel devices providing more and more environmentally sustainable solutions. After clay and nanotubes, graphene and its derivatives have become …

Interaction of emerging contaminants at the colloidal and planar interfaces : influence on environmental fate and transport
The increasing concerns regarding emerging contaminants in aquatic ecosystems provide a need to understand the role surface chemistry plays in the fate and transport of pollutants. The overarching aim of this thesis has been to investigate adsorption of selected emerging pollutants to colloids and …

Design of silica-based sustainable biomaterial adsorbents from agricultural waste for the microextraction and adsorptive removal of insecticides and antibiotics from wastewater samples
… often fail to completely remove these pollutants and are associated with high costs, energy intensity, and secondary pollution. To address these limitations, this study adopts a circular economy framework by transforming agricultural wastes such as palm fronds, corncobs, and sugarcane …

Resorcinol-formaldehyde/titania (RFTi) gel composites for wastewater treatment
… water pollution, together with the appearance of emerging pollutants, necessitates the development of efficient new techniques for water remediation. Conventionally, adsorption and environmental catalysis can effectively respond to this demand, and these methods can be enhanced by developing new …

Bioaccumulation of microcystins in terrestrial food plants and the development of novel sorbents for monitoring microcystins in irrigation water
… metros in South Africa, MCs co-exist with other pollutants such as metals and Linear Alkylbenzene Sulfonates (LAS), and these can have synergistic effects on the crops irrigated by such waters and exacerbate the human health risks posed by MCs. The current study investigated the bioaccumulation …

Impacts of ocean acidification and other (global change) stressors on marine invertebrates
… of temperature rises and contamination of emerging pollutants such as lithium on the sea snail are discussed in Chapter 5. To determine whether OA includes propagating effects in the ecotoxicological study, the amphipod A. brevicornis is described in Chapter, 6 and finally, whether …
