The Second International Symposium on the Risk Assessment of Manufactured Nanomaterials is held in Tokyo.

September 1, 2011


 This is the second international symposium in relation to the NEDO project "Research and Development of Nanoparticle Characterization Methods - Evaluating Risks associated with Manufactured Nanomaterials". The project was aiming at developing methods of characterization, exposure assessment and hazard assessment, and establishing risk assessment methods for manufactured nanomaterials using those methods, under the project leader, Dr. Junko NAKANISHI, and was completed in fiscal 2010 to achieve numerous results in collaboration with an OECD's nanosafety program. This two-day symposium is to disseminate the results of the project including risk assessment documents for carbon nanotubes (CNTs), fullerene (C60) and titanium dioxide (TiO2) nanoparticles and to provide an opportunity to discuss the implications of the project.

 The symposium will consist of a plenary session for general public on Day 1 and five breakout sessions for experts in three separate conference rooms on Day 2, both of which will include invited lectures from USA and Europe. The following printed materials will be provided to the participants at the venue:

 Lecture abstracts both in English and in Japanese

 Executive summaries of risk assessments of three manufactured nanomaterials: carbon nanotubes ( CNTs ), fullerene ( C60 ) and titanium dioxide ( TiO2 ), as well as a concept paper that explains the principles and basic approach to risk assessment of manufactured nanomaterials (English edition and/or Japanese edition)

"Methods of preparation and characterization of manufactured nanomaterials for toxicity testing" ( English edition and/or Japanese edition )

 After the symposium, lectures will be available on the web both in English and in Japanese.
