Canada expected to demand data from suppliers of nanomaterials
By Guy Montague-Jones, 16-Feb-2009

Canada is poised to become the first country to demand that companies report their use of engineered nanomaterials.

Information on quantity, usage and chemical data will be required as part of a one-off request from the Canadian government, according to the Project on Emerging Nanotechnologies (PEN) at the Woodrow Wilson International Center for Scholars.

Companies that manufactured or imported more than one kilogram of nanomaterial in 2008 will have to submit the information, said a spokesperson from Environment Canada.
