The California Department of Toxic Substances Control (DTSC) announced it will host the DTSC/California Nano-Industry Network Symposium, to be held November 16, 2009, in Sacramento, California. The Symposium, which is co-sponsored by the American Chemistry Council and Dupont, will use the DTSC’s nanotechnology data call-in as a backdrop. According to the preliminary agenda, the Symposium will feature two sessions. The first, entitled “Collaborative Efforts,” will discuss the key U.S. and international forums for collaboration on the health, safety, and environmental impacts of nanomaterials. The second session, “Company Engagement with Nanotechnology Safety,” will review examples of how companies can apply the evolving knowledge on nanomaterials safety to address systematically various areas of concern.
