An assessment of dioxins, dibenzofurans and PCBs in the sediments of selected freshwater bodies and estuaries in South Africa
(North-West University, 2007)Persistent organic pollutants (POPs) are a threat to the environment and human health because they are ubiquitous, resistant to degradation, can bio-accumulate in organisms and bio-magnify in food chains. They have a ... -
The determination of dioxin-like POPs in sediments and fish of the Vaal Triangle region, Gauteng, South Africa
(North-West University, 2006)Water resources in South Africa are scarce, and should therefore be protected against pollutants, also from persistent organic pollutants (POPs). This is emphasised by the Stockholm Convention on POPs, which aims at ... -
Determining uranium activity distribution in water streams and sediment in three mining regions of South African
(North-West University (South Africa), 2023)Uranium is a by-product in the mining of gold in South African landscapes (Coetzee et al., 2006). Since these activities are done on land in different provinces of South Africa and near communities inhabited by people ... -
Diversity of zooplankton and aquatic macroinvertebrates in the Ntsikeni Nature Reserve
(North-West University (South Africa). Potchefstroom Campus, 2017)The Ntsikeni Nature Reserve is one of 23 wetlands in South Africa that is designated as a Ramsar Wetland of International Importance. The Ntsikeni wetland complex comprises an area of 1070 ha, located within a provincial ... -
A holistic view on the impact of gold and uranium mining on the Wonderfonteinspruit
(North-West University, 2012)The Wonderfonteinspruit (WFS) flows through the richest gold mining region in the world and has subsequently been exposed to the related pollution for more than a century. In order to determine the extent of mining related ... -
Machine learning digital soil mapping to inform gully erosion mitigation measures in the Eastern Cape, South Africa
(Elsevier, 2020)Soil erosion is probably the most common form of land degradation, leading to on and off site detrimental effects, such as an increase in river sediment load which have been shown to drastically decrease dam storage capacity. ... -
Mobility potential of metals in acid mine drainage occurring in the Highveld area of Mpumalanga Province in South Africa: implication of sediments and efflorescent crusts
(Elsevier, 2017)Prediction of the dispersion of pollutants from the acid mine drainage is an important step toward the development of remediation strategy and mitigation of environmental impact. Geochemical studies are often carried out ... -
Nanomaterials in the aquatic environment: a European Union United States perspective on the status of ecotoxicity testing, research priorities, and challenges ahead
(Wiley, 2016)The European Union–United States Communities of Research were established in 2012 to provide a platform for scientists to develop a “shared repertoire of protocols and methods to overcome nanotechnology environmental health ... -
Persistent organic pollutants in biotic and abiotic components of the Orange-Senqu River basin
(North-West University (South Africa), 2023)The Orange-Senqu River Basin (OSRB) stretches over four southern Africa countries that are all Parties to the Stockholm Convention on Persistent Organic Pollutants (SCPOPs). The main tributary, the Vaal River on the eastern ... -
Polycyclic aromatic hydrocarbons (PAHs) in the aquatic ecosystems of Soweto and Lenasia
(North-West University (South Africa), Potchefstroom Campus, 2017)In South Africa, our scarce water resources are fully utilised and its quality threatened by pollution and therefore must be protected. One of the pollutant classes of concern is the polycyclic aromatic hydrocarbons (PAHs). ...
