The Water Research Group (Ecotoxicology) consists of academics and postgraduate students at the North-West University in South Africa who specialize in the ecotoxicology of nanomaterials. Different toxicological endpoints are used to determine the hazard of nanomaterials when released into the environment.
Currently we have three projects running testing the ecotoxicity of nanomaterials in aquatic and terrestrial ecosystems. Species which are focused on include bacteria, algae, daphnia, zebrafish, round worms, potworms, and earthworms.
Acute toxicity tests (bacteria, algae, earthworm, nematodes, daphnia, fish)
Chronic toxicity tests (various end points)
xCELLigence (real-time cell analysis)
Biomarker analysis (e.g. oxidative stress, oxygen consumption, cellular energy allocation, etc.)
Imaging techniques (TEM/SEM/CytoViva)
Swimming performance (Loligo)
Behaviour (Noldus and DanioVision)
If you have a project you would like to collaborate on or a question on any of the techniques we use please feel free to contact us.
We have obtained funding from the National Nanotechnology Equipment Programme of the National Research Foundation to develop the largest Zebrafish bioassay facility in Africa.
This facility will comprise of Techniplast holding systems technology. This state of the art facility will contain six Zebrafish housing systems, one quarantine stand alone system, four toxicity rack systems and two Xenopus housing systems.
Check out of new blog!! If you have any questions or comments please feel free to contact us.
