Assessment of DDT contamination in house rat as a possible bioindicator in DDT-sprayed areas from Ethiopia and South Africa
(Springer, 2017)Ethiopia and South Africa are among the few countries to still implement indoor residual spraying with dichloro-diphenyl-trichloroethane (DDT) for malaria vector control. In this study, we investigated the levels and ... -
Bioaccessibility and risk assessment of essential and non-essential elements in vegetables commonly consumed in Swaziland
(Elsevier, 2017)The green leafy vegetables (Mormodica involucrate, Bidens pilosa and Amaranthus spinosus) are economic; seasonal; locally grown and easily available; easy to propagate and store; highly nutritious food substances that form ... -
Brominated flame retardants in wild bird eggs from the industrialised heartland of South Africa
(Taylor & Francis, 2020)Brominated flame-retardants (BFRs), including polybrominated diphenyl ethers (PBDEs) and hexabromocyclododecane (HBCD), were analysed in 77 eggs of 13 wild bird species from Gauteng and northern Free State (the industrial ... -
Distribution and health risk assessment of organochlorine pesticides (OCPs) residue in edible cattle tissues from northeastern part of Egypt: high accumulation level of OCPs in tongue
(Elsevier, 2016)Food consumption is an important route of human exposure to organochlorine pesticides (OCPs). In order to assess the potential human health risks associated with OCPs, edible cattle tissues (liver, kidney and tongue) were ... -
Heavy metal threats to plants and soil life in Southern Africa: present knowledge and consequences for ecological risk assessment
(Springer, 2019)In recent times there has been remarkable development in the field of soil ecotoxicology and risk assessment (RA) models. It is, however, debatable if these RA models are robust representatives for worldwide relevance. In ... -
Is guideline-driven prophylaxis for venous thromboembolism common practice in the South African private hospital setting?
(AOSIS, 2020)Background: Prophylactic venous thromboembolism (VTE) strategies have the greatest impact on patient outcomes. Both global and local guidelines support VTE prophylaxis for hospitalised patients. However, studies have ... -
Levels of DNA methylation and transcript accumulation in leaves of transgenic maize varieties
(Springer, 2016)Background: Prior to their release in the environment, transgenic crops are examined for their health and environ‑ mental safety. In addition, transgene expression needs to be consistent in order to express the introduced ... -

The need for attuned soil quality risk assessment for non-Western humans and ecosystems, exemplified by mining areas in South Africa
(Elsevier, 2014)Worldwide, soils are under threat of deterioration and contamination due to anthropogenic activities. Whilst risk assessment of soils in Europe has been well studied, the same cannot be said of soils in Southern Africa. ...
