Human health risk from consumption of marine fish contaminated with DDT and its metabolites in Maputo Bay, Mozambique
(Springer, 2018)
Many countries with incidence of malaria, including those surrounding Maputo Bay, use dichloro-diphenyl-trichloroethane (DDT) to reduce mosquitoes. This study is the first to estimate the human health risk associated with ...
Evidence of impacts from DDT in pelican, cormorant, stork, and egret eggs from KwaZulu-Natal, South Africa
(Elsevier, 2019)
DDT remains in use for malaria control in South Africa. We quantified DDTs in aquatic bird eggs from the highly biodiverse northern KwaZulu-Natal, a province of South Africa where DDT has been used for more than 80 years ...
Using stable δ13C and δ15N isotopes to assess foodweb structures in an African subtropical temporary pool
(Taylor & Francis, 2020)
Southern Africa has one of the highest densities of temporary pools and some of the most understudied temporary wetlands in the world. Additionally, the eastern African annual killifishes (Nothobranchius spp.) are rare in ...
Bioaccumulation of persistent organic pollutants and their trophic transfer through the food web: human health risks to the rural communities reliant on fish from South Africa's largest floodplain
(Elsevier, 2019)
The Phongolo River Floodplain (PRF) is South Africa's largest floodplain, unique in being the only large floodplain able to sustain permanent waters throughout the dry season (Kyle, 2002). This highly productive region ...
Baseline bio-accumulation concentrations and resulting oxidative stress in Synodontis zambezensis after an acute laboratory exposure to 4,4′-DDT
(Elsevier, 2019)
The use of 1,1′-(2,2,2-Trichloro-1,1-ethanediyl)bis(4-chlorobenzene) (DDT) as a pesticide for the control of insects vectors responsible for the spread of many life threatening diseases was officially banned in 1972 by the ...
Concentrations and human health risk assessment of DDT and its metabolites in free-range and commercial chicken products from KwaZulu-Natal, South Africa
(Taylor & Francis, 2017)
Organochlorine pesticides such as dichlorodiphenyltrichloroethane (DDT) have been used in agriculture and for disease control purposes over many decades. Reports suggest that DDT exposure may result in a number of adverse ...
Biotransport of metallic trace elements from marine to terrestrial ecosystems by seabirds
(Wiley, 2019)
Physical systems, such as currents and winds, have traditionally been considered responsible for transporting contaminants. Although evidence is mounting that animals play a role in this process through their movements, ...
A glycomics approach to discover novel renal biomarkers in birds by administration of cisplatin and diclofenac to chickens
(Oxford Univ Press, 2018)
Avian species have a unique renal structure and abundant blood flow into the kidneys. Although many birds die due to nephrotoxicity caused by chemicals, there are no early biomarkers for renal lesions. Uric acid level in ...
Characterization of species differences in xenobiotic metabolism in non-experimental animals
(Pharmaceutical Society of Japan, 2017)
The ability to metabolize xenobiotics in organisms has a wide degree of variation among organisms. This is caused by differences in the pattern of xenobiotic bioaccumulation among organisms, which affects their tolerance. ...
Insights into the drivers of histopathological changes and potential as bio-indicator of riverine health of an aquatic apex predator from a premier conservation area: a multiple lines of evidence and multivariate statistics approach
(Elsevier, 2017)
There is a need for sensitive bio-monitoring and indicator tools in toxicant impact assessment to show the effect on fish health. Histopathological assessment of fish tissue is a bio-monitoring tool allowing for early ...
