Amelioration of iron mine soils with biosolids: effects on plant tissue metal content and earthworms
(Springer, 2016)The achievement of environmentally sound and economically feasible disposal strategies for biosolids is a major issue in the wastewater treatment industry around the world, including Swaziland. Currently, an iron ore mine ... -
Assessing the ecosystem support function of South African coal mining soil environments using earthworm (Eisenia andrei) bioassays
(Elsevier, 2021)Anthropogenic disturbances of soil environments predispose loss of soil ecosystem functions, including its habitat support function. In this study, the potential ecosystem support and habitat functions of soils from ... -
Earthworm (Eisenia Fetida) bioassay to assess the possible effects of platinum tailings disposal facilities on the environment along a gradient
(ALÖKI Applied Ecological Research and Forensic Institute Ltd., 2008)Platinum mines produce large amounts of inorganic tailings containing high levels of metals which are disposed of on tailings disposal facilities (TDFs) and there is no information available on their possible effects on ... -
Ecotoxicological assessment of chemical fumigants utilising an earthworm (Eisenia andrei) bioassay and soil microbial communities
(Springer, 2017)Fumigation is an important crop protection practice employed to control soil pathogens and diseases. Metham sodium and cadusafos are two commonly used soil fumigants for this purpose. However, little information is available ... -
Ecotoxicological effects of aflatoxins on earthworms under different temperature and moisture conditions
(MDPI AG, 2022)Aflatoxin contamination remains one of the most important threats to food safety and human health. Aflatoxins are mainly found in soil, decaying plant material and food storage systems and are particularly abundant during ... -
The effects of different gold mine tailings on growth, reproduction and avoidance-behaviour of earthworms
(Taylor & Francis, 2020)The mining industry plays a key role in the economic development of South Africa as one of the largest exporters of valuable resources, such as gold, platinum group metals and other metals and minerals. Unfortunately, ... -
Evaluation of organic matter stability in wood compost by chemical and thermogravimetric analysis
(University of Tehran (Graduate Faculty of Environment), 2012)This study investigated maturation and stability levels during composting of Quercus robur (QR) woodchips mixed with different nitrogen sources (horse manure, HM and lake mud, LM) for potential agronomic utilisation. The ... -
Utilizing an earthworm bioassay (Eisenia andrei) to assess a South African soil screening value with regards to effects from a copper manufacturing industry
(Springer, 2014)Metal contamination of soil due to industrialization has become an increasingly important problem in South Africa. This study aimed to investigate the potential impact of a copper (CuSO4·5H2O) production company on the ... -
Utilizing earthworm and microbial assays to assess the ecotoxicity of chromium mine wastes
(Elsevier, 2014)Mining plays an important role in the South African economy which results in environmental impacts. This holds a potential hazard for ecosystems surrounding mining areas and also for public health in the surrounding ... -
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 ...
