- Description
- Nanotechnology plays a key role in the technological revolution of this century. Singapore outranks the world as an investment destination and advancements in the field of nanotechnology is becoming a significant contributor to its growth. Currently there are a handful of companies and research organizations that are involved in the development, manufacturing and commercialization of nanomaterial products and applications in Singapore. However, very little research focuses on the toxicological aspects and occupational exposure of the nanomaterials that are being used. Moreover, the toxicological aspects that are studied mainly include in vitro testing, animal studies and cellular toxicities. It is important to note that in vitro studies may not take into account the translocation, toxico-kinetics and coordinated tissue responses towards the nanoparticles that are most likely to happen in vivo. Human exposure to nanomaterials and their effects are yet to be looked at and with the alarming differences in toxicity of nanomaterials compared to their non-nano counterparts, this angle of research comes as a necessity in the current scenario. This paper provides a summary of the toxicities of the nanomaterials that are being used in Singapore, namely, nano-titanium dioxide, nano-silver, nano-carbon, nano-cerium oxide, nano-calcium carbonate, nano-zinc oxide and nano-silicon carbide followed by a theoretical framework to determine the occupational exposure risks to nanomaterials in Singapore and possible management practices that could be employed to overcome this adverse situation.
