DDT and malaria prevention: addressing the paradox
Bouwman, Hindrik; Van den Berg, Henk; Kylin, Henrik (Superintendent of Documents, 2011)Background The debate regarding dichlorodiphenyltrichloroethane (DDT) in malaria prevention and human health is polarized and can be classified into three positions: anti-DDT, centrist-DDT, pro-DDT. Objective We ... -

Kylin, Henrik; Borgen, Anders R.; Nieuwoudt, Claudine; Bouwman, Hindrik; Quinn, Laura; Pieters, Rialet (RSC Publication, 2009)Currently very little data exists on the presence of persistent organic pollutants (POPs) and polycyclic aromatic hydrocarbons (PAHs) in the South African environment. To address this data gap a preliminary study of a ... -
Estimation of human body concentrations of DDT from indoor residual spraying for malaria control
Bornman, Riana; Bouwman, Hindrik; Fritsche, Lukas; Gyalpo, Tenzing; Scheringer, Martin (Elsevier, 2012)Inhabitants of dwellings treated with DDT for indoor residual spraying show high DDT levels in blood and breast milk. This is of concern since mothers transfer lipid-soluble contaminants such as DDT via breastfeeding to ... -
