„DDT and malaria control and POPs in South Africa”

6. - 8.4.2010


1. Malaria control using DDT and pyrethroids – Human exposure

Indoor Residual Spraying (IRS) of DDT and pyrethroids are mainstays of malaria control in many parts of Africa. I will present the basic concepts of malaria control, as well as the levels and dynamics of insecticides found in blood and breast milk of inhabitants.

2. Malaria control and insecticides – Residential and environmental dynamics3D DDT

Although IRS of insecticides is commonly practiced in the homes of millions of people in Africa and elsewhere, very little is understood of the dynamics of the applied insecticides, as well as how humans interact with these dynamics. I will also discuss some environmental issues.

3. Malaria control and insecticides – Human health concerns

Since the insecticides used in IRS are found in humans at appreciable levels, this lecture will investigate health concerns. I will touch on reproductive and neurological associations of these chemicals, as well as options, precaution, and risk reduction strategies.

4. Pollutants in bird eggs – South Africa and Mauritius

With more than 900 bird species in South Africa and associated oceans, levels of pollutants in these animals would be indicators of environmental levels of pollutants. I will introduce some of the work that has been done, and thoughts on why ecotoxicological concerns might be different in warmer climates.

5. Gold, birds, and cyanide

South Africa is well known for its vast gold reserves and mining operations. Cyanide is used in the recovery of gold from the ore, and the slurry is pumped on mine dumps. The supernatant still contains cyanide, but also attracts migratory and residential birds. The interaction and implications of these interactions will be discussed.

6. Crocodile mortalities

A seasonally dependant spate of mass crocodile deaths in the world-renowned Kruger National Park is a grave cause for concern. We understand some of the issues and factors, but a definite cause has not yet been found.

About the lecturer:

prof. BrowmanHenk Bouwman was born in 1958 in Johannesburg, South Africa. Part of his schooling was three years in Holland. After matriculating at Middelburg High School (Mpumalanga), he obtained his B.Sc (1981), B.Sc Hons (1982), M.Sc (1984) and Ph.D (1990) at the PU vir CHO. For his Ph.D he was a Medical Research Council bursar, working on the levels and dynamics of DDT, as used in malaria control, in humans, fish, birds and the environment. He started his career as a Medical/Senior Medical Researcher at the MRC (Environmental Diseases 1988-1990), Senior Lecturer (PU vir CHO, 1990-1995), Assistant Director and Specialist Scientist, Agricultural Research Council, 1996-1999), and Professor (PU vir CHO, 2000-current). He has published 48 refereed papers in scientific journals, and is involved in a number of projects, both as leader / co-ordinator, or as collaborator or advisor, with local and international research organizations (e.g. United Nations Environment Programme / Global Environment Facility, SIDA, Swedish University of Agricultural Sciences and ARC). He has travelled extensively overseas.
His work concentrates mainly on the ecology of birds and the so called Persistent Organic Pollutants (POPs). He has acted as advisor to the Government on POPs and has also been an accredited member of the South African team in international negotiation fora. Other aspects of his work relates to endocrine disruptors and the effects of pollutants on earthworms and birds. In 2000 he was appointed by the NWU as Professor in the School of Environmental Sciences and Development, and his research is conducted in the research focus area: Environmental Science and Management. His current teaching includes evolutionary theory, zoogeography and animal behaviour at the pre-graduate level, and various aspects of pollution and impact on the post-graduate level. He is currently leader and a co-leader for more than 10 M.Sc and Ph.D students on various aspects of pollution, POPs and birds.
He is now serving his second term as project evaluator for the Scientific and Technical Advisory Panel (STAP) of the Global Environment Facility with the responsibility of evaluating national and international applications for GEF sponsored projects.

Prof. Henk Bouwman about his expertise:

"I am mainly interested in eco-toxicology of organic pollutants. I have worked on earthworms, birds, fish, plants and humans, and am involved in DDT and malaria control research. I also have been involved in the Persistent Organic Pollutant Convention (POPs), or also known as the Stockholm Convention. I am involved in various kinds of impact and remediation studies, including quelea, bird ringing (banding), mining and polluted sites. My teaching concerns evolutionary theory, animal behaviour and zoogeography."
