California Targets Nanoscale Metal Oxides and Quantum Dots for Data Call Ins
California's Department of Toxic Substances Control (CDTSC) held a conference today during which they identified the next six nanoscale materials they intend to target in their second round of data call ins. Regular readers may remember that CDTSC targeted 26 manufacturers/importers of carbon nanotubes with its first data call in in 2009.
In addition to identifying the nanoscale materials which will be the subject of the data call in, CDTSC also provided a preliminary list of manufacturers/importers that will receive the data call in, as well as the proposed questions they will be asked. We cover each material below.
CDTSC also indicated that carbon nanotube manufacturers/importers will receive a second round of data call in questions.
CDTSC plans to issue all of these new data call ins sometime before the end of the year. Stay tuned . . .
