Research by RIVM shows that the participants in the so-called tROM project, their supervisors and other people involved may have been exposed to chromium-6.

Health effects due to exposure to titanium dioxide nanoparticles via food, food supplements and toothpaste cannot be excluded.

RIVM contributes to the safe use of nanomaterials through research, alerts and policy consultations, and this work is demonstrated in a short informative film.
