The Council of Canadian Academies has released a new report which warns that the health and environmental risks posed by nanomaterials are both serious and poorly understood. The CCA report also warns that "current [Canadian] regulatory triggers are not sufficient to identify all nanomaterials entering the market that may require regulatory oversight". That is, some – if not many – nanomaterials remain effectively unregulated, and don’t even trigger new safety assessments before they are used in products like cosmetics, sunscreens, food packaging or clothes.
