The European Commission’s Joint Research Centre’s (JRC) Institute of Health and Consumer Protection (IHCP) have published two papers on nanoparticle measurements relating to consumer products. The first deals with the measurement issues relating to enforcement of EU legislation on nanoparticles, taking into account the EU recommendation for the definition of a nanoparticle, whilst the second is a review of methods used for determining size distribution of nanoparticles in foods and consumer products.

In a seperate development, scientists in the UK and the USA have concluded that it is silver ions which cause harm to bacteria in the environment not silver nanoparticles. Their work shows that silver ions are released from silver nanoparticles, which are used as anti-bacterial agents in clothing (particularly socks), cosmetics and other household products. Work is currently starting in LGC to measure both nanosilver and ionic silver in domestic discharges to the environment.
