Safety implications of nanotechnology

The Australian Safety and Compensation Council (ASCC) has published a report reviewing the potential occupational health and safety implications of nanotechnology and nanoparticles.

Nanotechnology and nanoparticle effects on health and safety are mostly unknown because the sector is relatively recent; as a result, there is a lack of available information on human exposures and working conditions. The current technological limitation in measuring the nanoparticles in the workplace is also a factor contributing to the inability to accurately predict effects.

Animal and in-vitro test systems have indicated that there are possible consequences from nanoparticle use and exposures. Other animal studies suggest that lung pathologies (such as cancers, inflammation, granuloma formation, fibrosis and breathing difficulties) may be expected with exposures to carbon nanotubes and metal oxide nanopowders.

The report outlines the issues in nanotechnology safety which require attention. These include: the development of robust air monitoring systems to provide accurate information on worker exposures; setting priorities to acquire information to determine workplace exposure standards and worker protection; and chronic exposure studies in appropriate in vivo test systems.

The recommendations made by the ASCC regarding the nanotechnology industry include: maintain a constant watch on the area; move away from the current practice of using MSDS for nanoparticles; fund research in the development of nanoparticle measurement systems suitable for occupational settings; actively pursue interagency avenues to facilitate advancements in OHS and toxicological data necessary to establish nanoparticle workplace exposure standards and safe work practices; and the prevailing regulatory frameworks of government agencies should be examined to determine appropriateness to nanoparticles.
