Agrochemicals related to maize crops in South Africa and associated biological effects : an in vitro study
(North-West University (South Africa), 2023)Although agrochemicals reduce pest-associated crop losses, these chemicals end up in non-target environments following rainfall and irrigation. When fractions of agrochemical mixtures are bioavailable, they pose a threat ... -
Assessing the ecotoxicity of goldmine tailings by utilising earthworms and soil mesofauna as bioindicators
(North-West University (South Africa), 2019)The mining industry plays a key role in the economic development of South Africa, which as a country, is one of the largest exporters of valuable resources such as, gold, platinum group metals (PGMs) and other metals and ... -
Determining the effect of soil on bush encroachment between 1993 and 2018 in the North West Province
(North-West University (South Africa), 2022)Bush encroachment (BE) is a serious form of land degradation and South Africa alone has lost an estimated 8 million hectares (ha) of grazing or cultivation land due to BE. This consequently leads to decreased food security. ... -
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 ... -
Inoculation of carbon and nitrogen in growth mediums to promote seed germination in mine rehabilitation
(North-West University (South Africa), Potchefstroom Campus, 2015)The mining industry has been a vital component in the development of South Africa. Activities related to the mining industry have resulted in major impacts, both environmental and social. The rehabilitation of mining-disturbed ... -
An investigation into the potential of crude and partially separated material of selected non–crop plant species as control agents of root–knot nematodes (Meloidogyne incognita) in tomato
(North-West University, 2012)Plant-parasitic nematodes (PPN) are a serious problem in vegetable production and can cause severe damage to several crops. In rural, low-input farming nematode damage is much higher and yields can be completely destroyed. ... -
Persistent organic pollutants (POPs) in soil associated with an active incinerator in Potchefstroom, South Africa
(North-West University, 2005)POPs are a group of chemicals that have been extensively studied over the last few years. The main reason that these chemicals have received so much scientific attention is the myriad of negative effects they have on the ... -
Quantification of potential elemental impact of a munitions production and testing facility on its immediate surroundings
(North-West University, 2010)The study attempted to quantify the elemental concentrations and possible accumulation levels in the antelope's organ tissue at Rheinmetal Denel Munitions (RDM), as well as to correlate the findings with the surrounding ... -
The selection process of analogue parameters and criteria for rehabilitation design at Sishen mine
(North-West University (South Africa), 2016)According to the South African Mineral Petroleum Resources Development Act, 2002, the holder of a mining right must, as far as is reasonably practicable, rehabilitate the environment affected by mining operations to its ... -
Standardisation and implementation of an optimised method for lipid profiling of microbial communities
(North-West University (South Africa), 2016)Although the importance of phospholipid fatty acid (PLFA) analysis to characterise microbial communities has been recognised over the years, the vast number of modifications to this traditional method as well as discrepancies ...
