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 ... -
Assessing the effects of biochar as an ameliorant for biopesticide polluted soils utilising earthworms
(North-West University (South Africa), 2023)Two plant biopesticides, Bidens pilosa L. and Tagetes minuta L., were investigated for possible effects on earthworms and soil enzymatic activity, compared to the conventional pesticide, Fenamiphos. The efficacy of biochar ... -
Assessment of platinum mine tailings storage facilities : an ecotoxicological perspective
(North-West University, 2008)South Africa is one of the most important mining countries in the world, hosting the world's largest reserves of platinum group metals (PGMs). Even though mining is clearly an important activity in South Africa, contributing ... -
Characterization of bacteria isolated from a platinum mine tailings dam
(North-West University, 2012)Contamination from various sources has a huge impact on soil health and microbial community composition. Metal contamination of soil in mining scenarios is of concern and is not adequately addressed, particularly with ... -
Characterization of heavy metal tolerant bacterial plasmids isolated from a platinum mine tailings dam
(North-West University, 2012)The development of metal-tolerance and antibiotic resistance in bacteria may be caused by metals polluting a particular environment. During mining and mineral processing activities, large quantities of metals are deposited ... -
A comparative evaluation of two rehabilitation options employed to rehabilitate industrially generated elemental seepage on a coal mine
(North-West University, 2018)Mining has a very long history in South Africa and together with the mining activities comes environmental degradation. The mining sector makes use of a number of different procedures and products that causes this degradation ... -
Determining the ecotoxicity of nanodiamonds and quantum dots using the soil nematode Caenorhabditis elegans
(North-West University (South Africa), 2018)Engineered nanoparticles (ENP) are being used in many commercial products and applications, such as biological imaging, toothpaste and electronics. As the production, use and disposal of these products increase, environmental ... -
Ecotoxicity of CdTe and its functional groups on Enchytraeus albidus
(North-West University, 2018)Laboratory toxicity tests are used worldwide to assess the acute and chronic toxicity of specific pollutants to contribute towards the calculation of environmentally safe concentrations for nanomaterials (NMs). The field ... -
Ecotoxicological assessment of aflatoxin in soil under different temperature and moisture conditions utilising earthworms
(North-West University (South Africa), 2022)Aflatoxins are secondary metabolites produced by specific strains of fungi. These natural toxins are mainly found in soil, decaying vegetation, and food storage systems and are particularly abundant during drought stress. ... -
Ecotoxicological effect of CdTe quantum dots on Eisenia andrei
(North-West University (South Africa), 2020)Nanotechnology is a modern developing discipline producing a large quantity of consumer products, likely resulting in waste materials during the upcoming decades. Engineered nanoparticles with unique physicochemical ... -
The effect of cadmium on earthworms (Eisenia andrei) and their intestinal bacteria
(North-West University, 2018)Cadmium contamination, predominantly from anthropogenic activities such as mining, have a significant impact on soil organisms. It alters the abundance, diversity, community structure, ecological functions and the species ... -
The effect of fumigants on earthworms (Eisenia andrei) and soil microbial communities
(North-West University, 2015)Biofumigation is an important crop protection practice that uses a plant’s natural defence mechanisms to control agricultural crop pathogens and diseases. Glucosinolates are volatile compounds found in most Brassica species ... -
Effects of Temperature and Moisture on the Ecotoxicity of Metal-Based Fungicides Towards Earthworms
(North-West University (South Africa), 2022)Climate change is a major threat to biotic and abiotic ecosystems worldwide and might potentially affect the mobility and bioavailability of metals in soil. Anthropogenic activities such as mining, agriculture and the use ... -
Measuring rehabilitation success of coal mining disturbed areas : a spatial and temporal investigation into the use of soil microbial properties as assessment criteria
(North-West University, 2007)The rehabilitation of degraded soils, such as those associated with post-mining sites, requires knowledge of the soil ecosystem and its physical, chemical, and biological composition in order for rehabilitation efforts ... -
Microbial diversity and metal pollution from a platinum mine tailings dam in the North-West Province (RSA)
(North-West University, 2008)The aim of this study was to determine the effects of the heavy metal pollution on microbial diversity along the gradient from a platinum mine tailings dam using culture-dependent (plating methods) and molecular methods. ... -
Multi-species assessment of South African coal mine reclamation soils for ecosystem recovery
(North-West University (South Africa)North-West University, 2020)At present, there is no comprehensive soil quality assessment practice for the coal mining industry in South Africa. Studies have shown that belowground soil biota are crucial to soil ecosystem functioning and are sensitive ... -
Soil ecological risk assessments of selected South African soils
(North-West University, 2014)South Africa produces large amounts of solid mine waste, covering vast areas of land in the form of tailings dam facilities (TDF). Tailings material contains high levels of elements which poses potential risk for the ... -
Soil mesofauna as bioindicators to assess environmental disturbance at a platinum mine
(North-West University, 2007)South Africa is rich in mineral resources and is one of the leading raw material exporters in the world, of which the more important are gold, diamonds and platinum. Mining is essential for economic development, but also ... -
The use of biosolids in phytostabilization of iron ore tailings in Swaziland
(North-West University (South Africa), Potchefstroom Campus, 2016)Historically, mineral resources (such as tin, gold, iron ore and asbestos) have played an important role in advancing Swaziland economically. Nonetheless, the same mining activities of the past are the cause of a legacy ... -
Utilizing earthworm and microbial assays to assess the environmental effects of different mining activities
(North-West University, 2011)Mining has negative impacts on the environment, and is one of the main contributors to environmental pollution. This holds a potential hazard for ecosystems surrounding mining areas and also for public health in the ...
