Titanium dioxide nanoparticles: exposure limits to avoid occupational cancers

04/03/2021
With 17,000 tons produced or imported each year in France (according to industry declarations), titanium dioxide in nanoparticulate form is one of the most widely used nanomaterials in various industrial sectors: paints, glass, cosmetics, plastics, textiles, etc.
Many workers are therefore exposed to it, with a risk of pulmonary inflammation that can lead to the development of cancers.
The French National Agency for Health Safety (Anses) publishes today its recommendations for occupational exposure limit values (OELV ) to reinforce risk prevention for workers exposed to TiO2 nanoparticles by inhalation: OELV-8h of 0.80 µg/m3 and an estimated STELV-15 min of 4 µg/m3.
