" " Nanotoxicology and the risk assessment of nanomaterials is now a priority strategic thrust for South Africa's National Institute for Occupational Health. The Toxicology and Biochemistry Departments of the NIOH is currently setting up a Nano-toxicology Unit that will contribute to NIOH's efforts to support the responsible development of the nanotechnologies in South Africa.  The unit will focus on the risk assessment of engineered nano-particles in general and their toxicity assessment in particular."
