In the light of current knowledge and opinions of the EU Scientific and Advisory Committees and independent risk assessors, nanomaterials are similar to normal chemicals/substances in that some may be toxic and some may not.
Lähtudes praegustest teadmistest ja teadus- ja nõuandekomiteede ning sõltumatute riskihindajate arvamustest, on nanomaterjalid nagu tavalised kemikaalid või ained – mõned neist on toksilised, mõned mitte.
