1. For many years was actively involved in my own research programme and presented scientific papers at both local and international conferences. The outcome of one of these meetings was the establishment of a recognized threshold level of nitrous oxide pollution in operating theatres, thus decreasing the health risk of exposed personnel based on the research that I had done.
2. Following the concern about the effects of residual levels of anaesthetic gases in operating theatres on staff working in them, research was conducted over a ten year exposure period to trace concentrations of nitrous oxide and its affect on male and female fertility. This research subsequently made operating theatre personnel aware of the environmental hazards and scavenging systems were installed in operating theatres and dental surgeries.
3. Related to the above investigation into the effects of this anaesthetic agent on the intrauterine development of fetuses, further studies also included growth studies of the offspring.
4. Following this research regime it became clear that Vitamin B12 Deficiency can be induced by daily exposure to nitrous oxide. This lead to the research for my PhD. Following onto this I was invited to attend the One-Carbon-Metabolism Meeting for Experimental Biology in 1990 at Vermont Academy, Saxton’s River.
5. Invited by Dr. Jeff Lipman of the Baragwanath 50th Anniversary Committee to spearhead a symposium on humidification and its related hazards (related to Anaesthesia and Intensive Care of patients)
6. Have given seminars to pregnant women and female sports women on the following:
• special nutrient needs of women
• Vitamin B6 in treatment of pre-menstrual tension
• Diet and vitamin supplementation in female gymnasts and sportsmen and women
7. At present involved in education and a member of the Siyavula Volunteer team authoring text books for Natural Science and Life Science. These text books are freely available to all learners and educators.
