Assessment of the risks associated with nanomaterials
Updated on 21/09/2016
Keywords : Nanomaterials, Nanoparticles, Nanotechnologies
As with any chemical, the fate of nanomaterials in the human body and their associated potential toxicity depend mainly on their physico-chemical properties (size, shape, solubility, etc.). However, partly due to the specific properties of manufactured nanomaterials, scientific knowledge of traditional substances cannot be directly transferred to nanoscale forms. Today, the widespread dissemination of nanomaterials through a variety of consumer products calls for a better understanding of the exposure of workers in this sector to these nanomaterials, as well as exposure of consumers and the general population as a whole. In this context, the Agency has conducted several expert appraisals on these topics.

Titanium dioxide (TiO2) is used in many industrial and commercial applications (food additives, cosmetics, pigments) and comes in different forms, both micro- and nanometric. ANSES is conducting work to assess the risks associated with the different routes of exposure to TiO2, by ingestion and inhalation. Below is an update on the Agency’s various activities in this domain.
Exposure to silver nanoparticles
Updated on 11/04/2018
Keywords : Nanomaterials, Nanoparticles, Nanotechnologies
Silver nanoparticles are used in various industrial applications, in sectors such as food (additives, food packaging, internal linings of refrigerators), textiles (clothing and bedding) and cosmetic and hygiene products (toothbrushes, hair straighteners, disinfectant sprays, etc.). They are mainly used for their antibacterial and antifungal properties. However, it is still proving very difficult to obtain an inventory referencing all products containing silver nanoparticles in France and elsewhere in the world. In 2011, ANSES received a formal request to update knowledge on the assessment of health and environmental risks associated with exposure to silver nanoparticles.
