During the June 29-July 1, 2009, meeting of the United Nations (UN) Committee of Experts on the Transport of Dangerous Goods and on the Globally Harmonized System of Classification and Labeling of Substances (GHS), the Committee will discuss a paper entitled “Ongoing Work on the Safety of Nanomaterials.” The paper provides a summary of current activities by the European Union (EU), including the Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) program, International Organization for Standardization (ISO), and the Organization for Economic Cooperation and Development (OECD). The paper includes the following questions:
- Can it be considered, for the same chemical (same [Chemical Abstracts Service (CAS) Number] and purity) that nanomaterials with new properties have the same hazards as conventional form?
- Is it possible to distinguish for a same chemical, the properties of its different nanoforms?
- How can this be done? Should new endpoints be determined?
- To which extent information about nanomaterials need be provided?
- What kind of information is needed?
- What kind of communication tool is needed for this purpose?
- What kind of collaboration can be suggested in order to contribute to clarification of nanomaterials hazard classification and indeed to heath safety and environmental issues of nanomaterials?
