    • Prenatal Exposure to Aluminum and Status of Selected Essential Trace Elements in Rural South AfricanWomen at Delivery 

      Rollin, Halina B.; Nogueira, Claudina; Olutola, Bukola G; Channa, Kalavati; Odland, Jon Øyvind (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-07-15)
      This study sought to evaluate the in utero exposure to aluminum and status of selected trace elements in South African women at delivery since aluminum is known to be toxic in all developmental stages even at low concentrations. Serum aluminum was negatively correlated with aluminum in urine, both uncorrected and corrected for creatinine, which suggests the retention of aluminum in body stores. ...

    • Prenatal exposure to cadmium, placental permeability and birth outcomes in coastal populations of South Africa 

      Röllin, Halina B.; Kootbodien, Tahira; Channa, Kalavati; Odland, Jon Øyvind (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-11-06)
      Background The impact of prenatal exposure to cadmium (Cd) on birth outcomes is an area of concern. This study aimed to assess an impact of prenatal Cd exposure on birth outcomes in distinct coastal populations of South Africa. <p>Methods Cadmium was measured in maternal blood (CdB) (n = 641), cord blood and in maternal urine (n = 317). This investigation assessed the associations between CdB ...

    • Prenatal exposure to DDT and other selected environmental contaminants and their predictors in malaria and non-malaria areas in coastal KwaZulu Natal, South Africa 

      Channa, Kalavati (Doctoral thesis; Doktorgradsavhandling, 2014-02-20)
      Prenatal exposure to environmental toxicants is of major concern, as foetal development is one of the most sensitive life stages for endogenous and exogenous insults. Permeability of the placenta allows not only for environmental contaminants, but also contaminants released from maternal body stores during pregnancy, to be transferred to the foetus. Most of the exposure assessments in pregnant women ...

    • Reduction of in utero lead exposures in South African populations: Positive impact of unleaded petrol 

      Röllin, Halina B.; Olutola, Bukola G; Channa, Kalavati; Odland, Jon Øyvind (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-10-16)
      Background:<br>Prenatal exposure to lead (Pb) has been shown to have negative and irreversible health impacts on foetal and early childhood development, affecting morbidity and mortality in adulthood. This study aimed to assess in utero Pb exposure, examine birth outcomes, and identify confounding factors in the large cohort of South African population, following the legislated removal of Pb from ...
