Current regulations focus on assessing the safety of nanomaterials through a combination of existing chemical regulations and specific nano-focused guidelines. For instance, the REACH regulation in the EU requires companies to assess and manage the risks posed by chemicals, including nanomaterials. Similarly, the Toxic Substances Control Act (TSCA) in the USA has provisions for nanotechnology. Regulatory frameworks often require detailed risk assessments, including toxicity studies and environmental impact assessments.
