The contribution of physical and chemical sediment characteristics to environmental risk from an irrigation scheme in South Africa
(Springer, 2015)Purpose: The physical and chemical characteristics of sediment from a South African irrigation scheme were used to determine the sediment stressors within the system and to determine whether or not stressors have the ... -
Crossing the innovation chasm in the South African ferroalloy industry
(North-West University (South Africa), 2020)Exploratory research and an empirical study were conducted to define the perceived variables that affect the rate of technology adoption and increase the likelihood of successful innovation diffusion within the South African ... -
The involvement of metallothioneins in mitochondrial function and disease
(Bentham Science, 2010)Mitochondrial oxidative phosphorylation deficiency is accompanied by various down-stream, adaptive responses which play a key role in the varied phenotypes observed when mitochondrial dysfunction occurs. These responses ... -
Metal content in street dust as a reflection of atmospheric dust emissions from coal power plants, metal smelters, and traffic
(Springer Link, 2013)Resuspended street dust is a source of inhalable particles in urban environments. Despite contaminated street dust being a possible health risk factor for local population, little is known about the contribution of ... -
Preliminary assessment of contaminants in the sediment and organisms of the Swartkops Estuary, South Africa
(Elsevier, 2015)Urban estuaries are susceptible to metal and organic pollution, yet most remain understudied in South Africa with respect to the presence, concentrations and distribution of contaminants. Metal and organic chemical ... -
Soil mesofauna as bioindicators to assess environmental disturbance at a platinum mine in South Africa
(Elsevier, 2012)South Africa is rich in mineral resources and is one of the leading raw material exporters in the world. Mining is essential for economic development, but also has detrimental environmental consequences in the form of ... -
Trophic transfer of metals and OCP’s in organisms from a warm temperate and a subtropical intertidal rocky shore
(North-West University, 2018)Globally, of all the services and functions that ecological systems provide to human welfare, ± 63 % comes from the marine domain. Pollution of the ocean by means of metals and organochlorine pesticides pose a great threat ... -
The use of feathers in monitoring bioaccumulation of metals and metalloids in the South African endangered African grass-owl (Tyto capensis)
(Springer Link, 2013)Few studies have quantified metals in South African species and no published data on residues specifically in South African owl feathers exist. Tyto capensis is listed as vulnerable within South Africa, making it ... -
Utilizing Eisenia andrei to assess the ecotoxicity of platinum mine tailings disposal facilities
(Springer Link, 2013)South Africa is an important platinum mining country which results in environmental impacts due to the construction of tailing disposal facilities (TDFs). It is unclear what the effects of ageing are on the ecotoxicity ...
