B&C Consortia Management, L.L.C. (BCCM) is working with BASF Corporation (BASF) to create a consortium to provide the California Department of Toxic Substances Control (CDTSC) information on analytical methods that could be used to measure certain nanoscale materials in air, surface water, and soil. The collaborative project will involve adapting known methods used to measure these substances in other media to the analysis of environmental media. The term of the consortium will be at least two years, which can be modified by mutual agreement. On December 21, 2010, CDTSC issued a data call-in (DCI) for information regarding analytical test methods, and other relevant information, from manufacturers of nano silver, nano zero valent iron, nano titanium dioxide, nano zinc oxide, nano cerium oxide, and quantum dots. Experts within BASF will address issues concerning titanium dioxide and zinc oxide. BASF and BCCM seek other companies and experts to offer similar expertise for the remaining nanomaterials of interest and provide CDTSC with the help it needs.
