Environmental risks of nanomaterials

There are still gaps in our knowledge regarding the behaviour and fate of nanomaterials in the environment. The German Environment Agency (UBA) has addressed this problem in a project funded by the Federal Environment Ministry on the behaviour of nanoscale titanium dioxide (TiO2) in simulated sewage treatment plants and soils. On the basis of the results, UBA drew up recommendations for adapting the current OECD test guidelines, which were originally developed for conventional chemicals. A uniform basis for studying nanomaterials in the environment will only become established when the OECD guidelines have been adapted accordingly.
