Why are specific regulations necessary for nanomaterials?
Nanomaterials exhibit unique physical, chemical, and biological properties that differ significantly from their bulk counterparts. These differences can lead to varied interactions with biological systems and the environment, necessitating tailored regulations. For instance, the Registration, Evaluation, Authorisation, and Restriction of Chemicals (REACH) regulation in the European Union has been updated to include specific requirements for nanomaterials, ensuring their safe use and handling.
