How to estimate the potential hazard related to nanoparticles?
Main results
- The study of toxic effects of nanomaterials is still under development and many questions are unanswered.
- Nanoproducts' number grows very rapidly. It is therefore urgent to assess for each of them the likely routes of exposure and the potential toxicity.
- More research is needed to better understand specific particle properties and other factors that influence their toxicity.
- New toxicity methods have to be developed and validated. Potential impact on human health and environment should be tested over the entire life-span of the material.
