What are the key challenges in assessing the risks of nanotechnology?
Assessing the risks of nanotechnology presents several challenges:
- Characterization: Difficulty in characterizing the physical and chemical properties of nanomaterials. - Exposure Assessment: Limited data on exposure levels and lack of standardized measurement techniques. - Toxicology: Insufficient understanding of the toxicological profiles of various nanomaterials. - Regulation and Standardization: Need for harmonized regulatory standards and guidelines.
