The ubiquitous occurrence of emerging micropollutants (EMPs) in water is an issue growing environmental-health concern worldwide. However, there remains a paucity data regarding their levels and water. This study determined the EMPs namely: carbamazepine (CBZ), galaxolide (HHCB), caffeine (CAF), tonalide (AHTN), 4-nonylphenol (NP), bisphenol A (BPA) from Gauteng, Mpumalanga, North West provinces, South Africa using comprehensive two-dimensional gas chromatography coupled to high resolution...
Three wastewater treatment plants (WWTPs) located in Gauteng province South Africa were investigated to determine the diversity, co-occurrence and implications of their fungal communities using illumina sequencing platform network analysis. Phylogenetic taxonomy revealed that members assigned 6 phyla 361 genera. Basidiomycota Ascomycota most abundant phyla, dominated by genera Naumovozyma, Pseudotomentella, Derxomyces, Ophiocordyceps, Pulchromyces Paecilomyces. analysis existence OTUs...
Due to widespread occurrence of lipid lowering drugs such as statins, fibrates and their metabolites in the aquatic environments, there is a worldwide growing concern role water quality biota. However, this limited by ability address occurrence, distribution, fate eco-toxicological effects. This study focuses on quantification levels environments using Ultra-High Performance Liquid Chromatography coupled high resolution quadrupole time-of-flight mass spectrometry (UHPLC-QTOF-MS). The...
Though intensive research has been channeled towards the biotechnological applications of halophiles and other extremophilic microbes, these studies have not been, by any means, exhaustive. Saline environments still offer a vast diversity microbes with potential to produce an array natural products which can only be unlocked concerted efforts. In this study, combination culture molecular approaches were employed characterize halophilic bacteria from saltpan water samples profile their...
The indispensable nature of toxigenic fungi and mycotoxins in agricultural systems is worldwide concern, hence the need for surveillance studies to preserve public health. Thirteen dairy farms were surveyed 40 feeds varying collected analyzed mycotoxins. Estimated levels aflatoxins (AFs), fumonisin B1 (FB1), ochratoxin A (OTA), citrinin (CIT), zearalenone (ZEN), α-zearalenol (α-ZEL), β-zearalenol (β-ZEL), deoxynivalenol (DON), 3- 15-acetyl-deoxynivalenol (ADONs), HT-2 toxin (HT-2),...
Wastewater treatment plants (WWTPs) in South Africa, like is the case for most WWTPs around globe albeit capable of removing substantial quantities microplastics (MPs) and fact, treatments become ineffective those plastic particles less than 100 µm. As a consequence, receiving water bodies which final effluent discharged becomes highly polluted. The present research devoted to analysis pervasive MPs wastewaters plant located Gauteng Province, Africa using Pyrolysis – GC-TOF-MS. Based on...
TOPSIS, known as Technique for Order of Preference by Similarity to Ideal Solution, is an example a multi-criteria decision analysis (MCDA) tools useful making ranking or selecting alternatives based on multiple criteria. In this study, rankings dispersive-extraction solvents used in DLLME the extraction mifepristone tap water samples was performed assess their greenness. Two TOPSIS methods objective mean weight (TOPSIS-MW) and entropy (TOPSIS-Entropy) weighting were proposed. Criteria...
Abstract The presence of microplastics (MPs) is rapidly increasing in the environment, posing a significant threat to public health and ecosystem. To monitor impact MPs, it crucial have standardized detection methods MPs remediation techniques. Therefore, this study aimed use tannic acid-coated magnetite nanoparticles recover specifically polystyrene (PS) polyethylene terephthalate (PET), from water bodies. A facile method for recovery was established using synthesized (TA-Fe 3 O 4 ) as an...
In this study, Ag and Pd bimetallic nanoparticles were generated in situ polyethersulfone (PES) dope solutions, membranes fabricated through a phase inversion method. The characterized for various physical chemical properties using techniques such as FTIR, SEM, AFM, TEM, EDS, contact angle measurements. then evaluated their efficiency rejecting EOCs resistance to protein fouling. TEM micrographs showed uniform distribution of Ag/Pd within the PES matrix, while SEM images uniform, fingerlike...
The extent of removal pharmaceuticals by African-based wastewater treatment plants (WWTPs) is relatively unknown with various studies observing high concentrations in effluents. This mainly due to WWTPs still utilising the traditional methods which are known be less effective. In this study, 15 selected antibiotics (amoxicillin, ampicillin, azithromycin, ciprofloxacin, doxycycline, erythromycin, gentamicin, metronidazole, norfloxacin, ofloxacin, penicillin, sulfamethoxazole, sulfapyridine,...
ABSTRACT The versatility of vat photopolymerization additive manufactured (VPAM) elastomers garners much interest in the production medical supplies and microfluidic devices. However, little research has characterized liquid barrier properties chemical resistance specifically related to these emerging acrylate‐based VPAM polymers. Herein, we describe a systematic approach studying structure–property relationships for series 3D printable from commonly used monomers crosslinkers, including...
