A Washington think tank is investigating development of a universal monitor for nanomaterials. Nanomaterials are already being manufactured with nanostructures similar to toxic workplace substances like asbestos. For now, there is no easy way to test the health effects of nanomaterials. Standard monitoring procedures are in place for most known toxic materials. But current monitoring techniques measure only the amount of material present, comparing that against known toxic exposure levels. Until the necessary parameters are determined for nanomaterials, it remains impossible to measure toxicity or monitor exposure.
