Characterising the scale and significance of persistent organic pollutants in South African sediments
(North-West University, 2010)Water resources in South Africa are scarce, and should therefore be protected against pollutants, also from persistent organic pollutants (POPs). POPs are a global concern due to their ubiquitous presence, persistence ... -
In vitro determination of the endocrine disrupting capacity of microplastics
(North-West University (South Africa), 2022)Since the development of plastic in the early 20th century, it has become essential in day-to-day living. The demand for plastic has grown exponentially to a point where there are over 300 million tonnes of plastic produced ... -
Persistent organic pollutants in the Olifants River Basin, South Africa: bioaccumulation and trophic transfer through a subtropical aquatic food web
(Elsevier, 2017)This study investigates the trophic transfer of persistent organic pollutants (POPs: PCBs, PBDEs, OCPs and PFASs) in the subtropical aquatic ecosystem of the Olifants River Basin (South Africa) by means of trophic magnification ... -
Possible endocrine disruption in molluscs from the Limpopo Province
(North-West University, 2010)With parts of SA in a malaria endemic area, a preventative way of fighting malaria is with the use of pesticides such as 1,1,1–Trichloro–2,2–bis(pclorophenyl) ethane, also known as DDT. DDT is listed under the persistent ... -
The presence of persistent organic pollutants and heavy metals in sediment samples from rivers in the Kruger National Park
(2015)Since 2008, large numbers of Nile crocodile (Crocodylus niloticus) carcasses were found in the Kruger National Park (KNP), South Africa. Most of the crocodile carcasses were found in the Olifants Gorge, which is situated ... -
The trans-continental distributions of pentachlorophenol and pentachloroanisole in pine needles indicate separate origins
(Elsevier, 2017)The production and use of pentachlorophenol (PCP) was recently prohibited/restricted by the Stockholm Convention on persistent organic pollutants (POPs), but environmental data are few and of varying quality. We here present ... -
Water loss under controlled humidity and temperature regimes in relation to bird eggshell thickness
(North-West University (South Africa), 2020)The African Penguin (Spheniscus demersus) is an Endangered species occurring along the Indian and South Atlantic coasts of South Africa. There are many suspected causes for the precipitous decline in their numbers. Previously, ...
