International agreements are crucial for several reasons: 1. Standardization: They help establish common standards and best practices for the safe production, handling, and disposal of nanomaterials. 2. Safety and Environmental Protection: Agreements promote research and policies that minimize potential health risks and environmental impacts associated with nanotechnology. 3. Collaboration: They facilitate international collaboration in research and development, enabling countries to pool resources and expertise. 4. Trade: Harmonized regulations help in the smooth trade of nanotechnology-enabled products across borders. 5. Ethical Considerations: These agreements often address ethical issues related to the use of nanotechnology in various sectors.
