Current focus Safety Testing of a Representative Set of Manufactured Nanomaterials Objective: To test Current focus Safety Testing of a Representative Set of Manufactured Nanomaterials Objective: To test an agreed representative set of manufactured nanomaterials using appropriate test methods. Aim: To understand the types of information on intrinsic properties that may be relevant to exposure and the effects assessment of MNs. In close co-ordination with other OECD work on Chemical Safety: Test Guidelines, Mutual 8 Acceptance of Data

Implementation - Two Stages Stage 1 Agreement on: i) A list of MNs (based Implementation - Two Stages Stage 1 Agreement on: i) A list of MNs (based on materials which are now, or soon to enter, commerce) ; and ii) A list of endpoints for which these MNs should be tested. Stage 2 Development of a programme to test MNs for human health and environmental safety 9

Stage 1: List of Manufactured Nanomaterials (14) ►Fullerenes (C 60) ►Titanium dioxide ►Single-walled carbon Stage 1: List of Manufactured Nanomaterials (14) ►Fullerenes (C 60) ►Titanium dioxide ►Single-walled carbon nanotubes (SWCNTs) ►Aluminium oxide ►Multi-walled carbon nanotubes (MWCNTs) ►Zinc oxide ►Silver nanoparticles ►Polystyrene ►Iron nanoparticles ►Dendrimers ►Carbon black ►Nanoclays ►Cerium oxide ►Silicon dioxide 10

Stage 1: List of Endpoints ►Nanomaterial Information/Identification (9 endpoints) ►Physical-Chemical Properties and Material Characterization Stage 1: List of Endpoints ►Nanomaterial Information/Identification (9 endpoints) ►Physical-Chemical Properties and Material Characterization (16 endpoints) ►Environmental Fate (14 endpoints) ►Environmental Toxicology (5 endpoints) ►Mammalian Toxicology (8 endpoints) ►Material Safety (3 endpoints) 11

Stage 2: Sponsorship Programme The sponsorship programme is an international effort to share the Stage 2: Sponsorship Programme The sponsorship programme is an international effort to share the testing of an agreed set of manufactured nanomaterials selected by the WPMN. Two phases: • Phase 1: To test selected MNs for the selected endpoints (official launch of phase 1: November 2007) • Phase 2: phase 1 will identify those cross-cutting issues or tests that will need further consideration 12 by the WPMN

Sponsorship Programme Work in Progress Phase 1 • Launched November 2007 • OECD Secretariat Sponsorship Programme Work in Progress Phase 1 • Launched November 2007 • OECD Secretariat is the clearing house to ensure coordination • Development of a guidance manual for sponsors to guide the testing • Workshop in Korea will assist Sponsors in their development of Dossier plans (November 2008) 10 Draft Dossier Development Plans were considered by the 5 th WPMN (March 2008) 13
