The Canadian Department of the Environment has published a Significant New Activity Notice for potassium titanate under the Canadian Environmental Protection Act. The nanoscale version of this substance has specific reporting guidelines assigned to it: 'a significant new activity is...any use in a quantity greater than 10kg in any one calendar year where the substance is engineered to contain particles...ranging from 1 to 100 nanometres in one or more directions'. The authority believes that 'a significant new activity in relation to the substance may result in...[it] becoming toxic' under Canadian law.
