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.

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.
Tool for control banding the risks associated with nanomaterials

Keywords : Nanomaterials, Nanoparticles, Nanotechnologies
The properties of manufactured nanomaterials pave the way for a great variety of promising technological developments. However, there are many uncertainties involved in making a quantitative assessment of the hazards of and exposures to nanomaterials, which will only be resolved gradually through progress in scientific knowledge of their properties and associated hazards.ANSES is applying considerable resources to addressing these issues, and in 2010 producedan expert report on the development of a control banding tool for specific risks in the case of nanomaterials.
