Nanoparticles are particles of matter that are at atomic and molecular levels. Working at these levels, you can modify the characteristics of materials and even develop materials tailored to specific needs. Nanotechnology is an emerging technology whose risks are not completely known. Cases have been reported about nanoparticles used in cosmetics entering the users’ bloodstreams.
The Standing Committee on Health of the Canadian House of Commons produced a document titled Evidence that reported the discussion of a session on understanding nanotechnology, meant for the members of the committee. The discussions focused on the risks posed by the new technology.
The Director, Research and Expertise Support Department, Institut de recherche Robert-Sauvé en santé et en sécurité du travail (IRSST), Mr.Ostiguy, explained that over 1000 products containing nanoparticles are presently available in the market.
He continued that the production processes posed the greatest risks to the workers carrying these out. This group included researchers who develop new products, employees in companies that synthesize the nanoparticles and employees of companies that introduce nanoparticles into their production lines for value addition purposes.
IRSST has researched current scientific knowledge about the risks posed by nanoparticles.
