Halogenated pollutants in terrestrial and aquatic bird eggs: converging patterns of pollutant profiles, and impacts and risks from high levels
(ELSEVIER, 2013)
We investigated the presence, levels, relationships, and risks of HCHs, DDTs, chlordanes, mirex, PCBs, and brominated flame retardants (BFRs) in terrestrial and aquatic bird eggs from an area in South Africa where DDT is ...
DDT exposure of frogs: a case study from Limpopo Province, South Africa
(Elsevier, 2016)
Amphibians are globally under pressure with environmental contaminants contributing to this. Despite caution aired more than 80 years ago of threats posed to amphibians by DDT spraying for disease vector control, no data ...
Long-term decreases in persistent organic pollutants in South African coastal waters detected from beached polyethylene pellets
(Elsevier, 2012)
Polyethylene pellets provide a convenient means to monitor Persistent Organic Pollutants (POPs) in marine
systems. Pellets collected between 1984 and 2008 at three South African beaches were analysed for
PCB, HCH and ...
Implications for health education and intervention strategies arising from children's caregivers concerns following successful malaria control
(Elsevier, 2012)
Malaria is still responsible for 10% of the total disease burden in Africa. This study was an empirical investigation addressing the extent to which, and the ways in which, sociocultural, family-based, demographic and ...
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 ...
Linking organochlorine exposure to biomarker response patterns in Anurans: a case study of Müller’s clawed frog (Xenopus muelleri) from a tropical malaria vector control region
(Springer, 2018)
Organochlorine pesticides are highly persistent in aquatic ecosystems. Amphibians, specifically anurans, play an intricate part in the aquatic food web, and have very permeable skin which makes them prone to bioaccumulation ...
Bone density and asymmetry are not related to DDT in House Sparrows: insights from micro-focus X-ray computed tomography
(Elsevier, 2018)
In organisms, DDT (Dichlorodiphenyltrichloroethane) and its metabolites, DDE (Dichlorodiphenyldichloroethylene) and DDD (Dichlorobischlorophenylethane) are endocrine mimics. They can influence bone density and other bone ...
