Exposure assessment of metal-based nanoparticles in aquatic environments: interactive influence of water chemistry and nanopaticle characteristics

Author: Thwala, Melusi ; Radebe, N ; Tancu, Y ; Musee, N Date: Sep 2014 Transformation and bioavailability information of engineered nanoparticles (ENPs) in environmental systems impedes assessment of their potential risks to aquatic environments. In aqueous environments ENPs undergo numerous transformation ... Read more
Fate and behavior of ZnO- and Ag-engineered nanoparticles and a bacterial viability assessment in a simulated wastewater treatment plant

Author: Musee, N ; Zvimba, JN ; Schaefer, Lisa M ; Nota, N ; Sikhwivhilu, LM ; Thwala, Melusi Date: 2014 The fate and behaviour assessment of ZnO- and Ag-engineered nanoparticles (ENPs) and bacterial viability in a simulated wastewater treatment plant (WWTP) fed with municipal wastewater was investigated through determination of ENPs stability ...

Genotoxicity of metal based engineered nanoparticles in aquatic organisms: A review

Author: Mahaye, Ntombikayise ; Thwala, Melusi ; Cowan, DA ; Musee, Eunice Date: Jul 2017 Engineered nanoparticles (ENPs) are an emerging class of environmental contaminants, but are generally found in very low concentrations and are therefore likely to exert sub-lethal effects on aquatic organisms. In this review, we: (i) highlight ... Read more
Interactions of metal-based engineered nanoparticles with aquatic higher plants: A review of state of current knowledge

Author: Thwala, Melusi ; Klaine, SJ ; Musee, N Date: Jan 2016 The rising potential for the release of engineered nanoparticles (ENPs) into aquatic environments requires evaluation of risks in order to protect ecological health. The present review examined knowledge pertaining the interactions of metal-based ... Read more
Monitoring fate and behaviour of Nanoceria under relevant environmental conditions

Author: Tancu, Y ; Thwala, Melusi ; Musyoka, Nicholas M ; Musee, N Date: Nov 2014 The exponential use of engineered nanoparticles (ENPs) in commercial applications and of their resultant increasing release into the aquatic systems raises concerns as their potential impacts are unknown. According to the Organisation for ... Read more
The oxidative toxicity of Ag and ZnO nanoparticles towards the aquatic plant Spirodela punctuta and the role of testing media parameters

Author: Thwala, Melusi ; Musee, N ; Sikhwivhilu, L ; Wepener, V Date: Sep 2013 The toxicity effects of silver (nAg) and zinc oxide (nZnO) engineered nanoparticles (ENPs) on the duckweed Spirodela punctuta were studied to investigate the potential risks posed by these ENPs towards higher aquatic plants. The influence of ... Read more
Potential susceptibility inhibitory effect of Ag and ZnO engineered nanoparticles on bacterial strains: effect of pH and temperature

Author: Mboyi, A ; Musee, N ; Zvimba, JN ; Momba, MNB Date: Aug 2013 The economic and social benefits of metallic silver (n-Ag) and zinc oxide (n-ZnO) engineered nanoparticles (ENPs) applications in medical, technological, environmental remediation, consumer products, among other have widely been demonstrated. ...
