Dermal exposure and skin barrier function of petrochemical workers exposed to polycyclic aromatic hydrocarbons
(North-West University, 2012)Aims and Objectives ? The aim of this study was the following: (1) to assess the dermal exposure of workers to PAH‘s during an entire eight hour work shift; (2) to assess the short term dermal exposure of workers to PAH‘s ... -
Evaluation of thermal desorption as an alternative technique for the measurement of coal tar pitch volatiles
(North-West University, 2011)Motivation: The accurate and reliable measurement of the concentration of coal tar pitch volatiles (CTPVs) in ambient air has proved to be a challenge for occupational hygienists. The challenge must however be confronted ... -
Photocatalytic activity of Gd2O2CO3·ZnO·CuO nanocomposite used for the degradation of phenanthrene
(Springer, 2019)Multimetal oxides nanocomposite photocatalysts based on Gd2O2CO3·ZnO·CuO were prepared by a co-precipitation method and carefully characterized using a range of analytical techniques. More specifically, analysis by X-ray ... -
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 ... -
Respiratory exposure during the additive manufacturing of sand casting moulds
(North-West University (South Africa) , Potchefstroom Campus, 2016)Background: During additive manufacturing (AM) of sand casting moulds, potential dust species of unknown particle size or mineral composition, and hazardous chemical substances (HCS’s) such as silica (crystalline), volatile ... -
Sol-gel preparations of ZnO/SnO2 composite photocatalysts applied for the degradation of PAH’s under visible light
(EARET, 2018)Wastewater treatment challenges faced by conventional methods have necessitated the need for alternative/complementary methods that are environmentally benign and efficient especially toward recalcitrant organic pollutants. ...
