Agrochemicals in freshwater systems and their potential as endocrine disrupting chemicals: a South African context
(Elsevier, 2021)South Africa is the largest agrochemical user in sub-Saharan Africa, with over 3000 registered pesticide products. Although they reduce crop losses, these chemicals reach non-target aquatic environments via leaching, spray ... -
Application of a Sediment Quality Index for the assessment and monitoring of metals and organochlorines in a premier conservation area
(Springer, 2015)The physical and chemical characteristics of surface sediments from a leading conservation area, namely the Kruger National Park, were determined in order to identify potential stressors in the systems that may contribute ... -
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 ... -
Assessment of phytobenthos in the lower Phongolo River catchment in relation to changing environmental conditions
(North-West University (South Africa), 2020)Floodplain ecosystems are important since they provide numerous services and resources, including food, wood and water to humans. The lower Phongolo River floodplain is one such ecosystem and is the most unique and diverse ... -
Associations between DDT and egg parameters of the House Sparrow Passer domesticus from the Thohoyandou area of South Africa
(Elsevier, 2018)This study investigated whether the pesticide DDT (Dichlorodiphenyltrichloroethane) and its metabolites, DDE (Dichlorodiphenyldichloroethylene) and DDD (Dichlorobischlorophenylethane) were associated with adverse effects ... -
Biomarkers in tigerfish (Hydrocynus vittatus) as indicators of metal and organic pollution in ecologically sensitive subtropical rivers
(Elsevier, 2018)Studies have shown high levels of contamination of both metals and organochlorine pesticides (OCPs) in aquatic systems of the world renowned Kruger National Park, South Africa. With effects evident in top predators, ... -
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 ... -
Chlorinated, brominated, and fluorinated organic pollutants in Nile crocodile eggs from the Kruger National Park, South Africa
(Elsevier, 2014)Repeated annual episodes of Nile crocodile deaths in two isolated areas of the Kruger National Park prompted the investigation of possible organohalogen pollutant involvement. Crocodile eggs were collected close to one of ... -
Current status and future prognosis of malaria vector control pesticide ecotoxicology and Xenopus sp.
(Springer, 2020)Anurans from the genus Xenopus have long been used as standard testing organisms and occur naturally in tropical and sub-tropical areas where malaria vector control pesticides are actively used. However, literature on the ... -
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 ...
