Description

The objectives of this project are:

– to test the suitability of existing OECD testing guidelines for nanoscaled amorphous silicon dioxide (NASD) and ZnO;
– to subject these test materials to OECD guideline testing;
– to supplement these guidelines with optional modifications aiming at addressing particle-specific features of toxicity testing;
– to include promising in vitro correlates in the test programme;
– to perform a proper characterisation of NASD/ZnO as well as of a fine fraction reference material;
– to evaluate – based on the results – the potential need to modify or supplement methods of standard tests for nanomaterials including administration methods;
– to propose a tiered testing strategy for these nanoparticles.

The project will present modified testing protocols meeting the special needs for nanoparticle testing (translocation potential; systemic availability and elimination; effects on remote organs besides the respiratory tract) as compared to fine particles.
