Prof Riana Bornman is a lecturer, Extraordinary Professor and Head of Andrology in the Department of Urology in the Faculty of Health Sciences. She is also Extraordinary Professor in Environmental Health at the School of Health Systems and Public Health. Prof Bornman’s area of expertise centres on the adverse health effects of the use of DDT as pesticide. She is currently involved in a study of DDT and the loss of clinically recognised pregnancies in South Africa.
A report to the South African Water Research Commission (WRC) on ’DDT for malaria control: Effects in indicators and health risk’ of which Prof Bornman was the project leader, was completed and submitted in 2009. Since 2008 Prof Bornman has acted as temporary adviser to the Stockholm Convention on Persistent Organic Pollutants (WHO/UNEP) and to the World Health Organisation (WHO) Consultation on DDT Hazard Assessment. She was also consulted at the WHO DDT Exposure Assessment Expert Meeting at the University of Bradford, UK in December 2009. She is a Working Member of the Group of the UNEP/WHO effort to update the endocrine disrupter chemical (EDC) document of 2002.
Prof Bornman holds membership of various national and international societies, including the International Society of Environmental Epidemiology (ISEE), the Society of Environmental Toxicology and Chemistry (Europe) (SETAC) and the African Branch of the Society of Environmental Toxicology and Chemistry (SETAC Africa). Prof Bornman has been an invited speaker at many conferences and workshops around the globe.
