Consultant: Nano Products Need Risk “Categories”
Much of the focus in the debate over toxicity and testing in the world of nanomaterials is on how researchers can tackle the seemingly impossible task of understanding every single thing that contains these tiny particles and structures.
Donald Ewert has another idea, based on a longtime system used for pharmaceuticals: categories.
"What if we could look at these things and say, ‘Oh, that's a Category E, that's a bad one.' Or, "That's a Category A, that's nothing to worry about'?" Ewert asked during a presentation at a recent Washington, D.C. workshop. The event brought U.S. and European Union officials together to push toward concrete action on steps for nano-related safety.
