The Supplement contains Documentation for the substances that were on the Notice of Intended Changes for 2016, with their corresponding values and notations that have been approved and adopted as Threshold Limit Values (TLVs®) and Biological Exposure Indices (BEIs®).
Engineered nanomaterials are fascinating. Just by making stuff smaller researchers have discovered forms of materials and even completely new materials that can be applied as diversely as better drugs, better paints or faster electronics. Using chemicals in a nanoscale version can completely alter their nature.
