The Strategic Approach to International Chemicals Management (SAICM) Secretariat seeks input from stakeholders by May 1, 2011, for a forthcoming report on nanotechnologies and manufactured nanomaterials, which will focus on issues relevant to developing countries and countries with economies in transition. The report will include ten sections, covering beneficial uses of nanomaterials for health and the environment; economic and social impact; and work of international organizations. A section on risk assessment and management will focus on seven subtopics, including material characterization and risk management across the life cycle. The SAICM Secretariat intends to prepare a report based on the input it receives for consideration at the Open-Ended Working Group meeting, scheduled for August 29-September 2, 2011, in Belgrade, Serbia.
