Adsorption of metal ions from fine coal tailings dump waste water using bio-char
(EARET, 2018)Coal mining operations produce large amounts of tailings which contains heavy metals. Heavy metals such as cadmium (Cd) can cause environmental problems. The adsorption capacities of biochars produced from spent coffee ... -
Biosorption of cadmium from water using surfactant impregnated eggshell
(EARET, 2018)Cadmium (Cd) is regarded as one of the most toxic elements and it causes water pollution when it exceeds the permissible limit. It is currently present in the Mooi River above these permitted levels, and must therefore ... -
Concentrations and compositions of metallic elements in commercially important marine species
(North-West University (South Africa), 2020)Metals have been in our environment since the genesis of the world and are ubiquitous in all environments. We as humans mine, utilize, and release these metals from the environment to a level that may affect chronically ... -
Concentrations and relative compositions of metallic elements differ between predatory squid and filter-feeding sardine from the Indian and South Atlantic oceans
(Elsevier, 2020)Although metallic elements occur naturally, they can occur or accumulate in organisms at levels toxic to the organism and/or their consumers. Concentrations of twenty-nine metallic elements in muscle tissue from sardine ... -
Concentrations of metallic elements in kidney, liver, and lung tissue of Indo-Pacific bottlenose dolphin Tursiops aduncus from coastal waters of Zanzibar, Tanzania
(Elsevier, 2017)Concentrations of metallic elements in kidney, liver and lung tissues of Indo-Pacific bottlenose dolphins Tursiops aduncus from coastal waters of Zanzibar were determined using inductively coupled plasma – optical emission ... -
Contamination status and accumulation characteristics of heavy metals and arsenic in five seabird species from the central Bering Sea
(Japanese Society of Veterinary Science, 2017)Seabirds are marine top predators and accumulate high levels of metals and metalloids in their tissues. Contamination by metals in the highly productive offshore region has become a matter of public concern. It is home ... -
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 ... -
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 ... -
Heavy metals in seaweeds from a polluted estuary in coastal Maine
(New England Botanical Club, 2017)Seaweeds (macroalgae) accumulate heavy metals from seawater and can therefore serve as biological monitors of marine pollution. In this paper, we present data on the tissue chemistry of seaweeds from the area of Callahan ... -
Hydrothermal preparation of biochar from spent coffee grounds, and its application for the removal of cadmium from coal tailings leachate
(SAIMM, 2019)Spent coffee grounds were transformed into biochar using a hydrothermal method. Some of the biochar product was pre-treated through surfactant impregnation with sodium dodecyl sulphate (SDS) to enhance its adsorption ...
