Chemical Information Call-in: Round Two Quantum Dots, Nano Metals, and Nano Metal Oxides For the second call-in, DTSC requested information about six chemical substances: quantum dots, nano silver, nano zero valent iron, nano cerium oxide, nano titanium dioxide, and nano zinc oxide. DTSC searched scientific literature and publicly available data sources, hosted a public workshop, and met with various manufacturers, importers, researchers, and others as part of the call-in process for obtaining information about these chemical substances. DTSC sent formal request letters on December 21, 2010, and January 4, 2011, to 45 entities which were identified as producers or importers of one or more of the six chemical substances in or to California. These letters required manufacturers and importers to submit their responses within one year. DTSC sent a follow-up letters to remind companies that had not yet responded. The Round Two responses for quantum dots, nano metals, and nano metal oxides were: | Company
