European (EU) legislation for plastic materials and articles states that engineered nanoparticles �may lead to different toxicological properties and therefore these substances should be assessed on a case-by-case basis by the (European Food Safety) Authority as regards their risk until more information is known about such new technology�. These concerns, with respect to migration and toxicity, have limited commercialisation of nanoparticle containing food contact materials. An overview of the EU legislation will be presented as well as the results of studies on the migration of nanoparticles (nano-silver and nano-clay). In addition to studying the migration behaviour of nanoparticles, their toxicity and their environmental fate and behaviour once ultimately disposed of needs to be considered too and will be described.  The presentation will conclude by summarising some ongoing work at Fera on the mammalian toxicokinetics of nano-particulate titanium dioxide and the disposition and environmental fate of some polymer-based nanoformulations.
