The California Environmental Protection Agency’s Department of Toxic Substances Control (DTSC) initiated the second chemical information call-in on nanometal oxides (titanium dioxide, cerium oxide, and zinc oxide), nanometals (silver and zero valent iron), and quantum dots in 2011. These materials are of interest to DTSC because they are currently used in many available commercial products. However, data on their unique properties are largely unavailable and their unique properties might have the potential to adversely effects to human health and the environment. DTSC sent a formal information request letter to manufacturers who produce or import the six nanomaterials in California, or who may export them into the State. DTSC is exercising its authority under California’s Health and Safety Code, Sections 57018-57020. In the second information call-in, DTSC is specifically interested in information related to analytical test methods for these chemicals in environmental matrices, including water, air, soil, and waste. The chemical information call-in is the world’s first mandatory program to address an approach for safe nanotechnology. The information call-in will help develop the information on nanomaterials and will identify gaps that could be filled to better protect human health and the environment.
