The “2nd Quantifying Exposure to Engineered Nanomaterials from Manufactured Products (QEEN II) Workshop” will be held October 9-10, 2018, in Washington, D.C. Sponsored by the Consumer Product Safety Commission (CPSC) and co-hosted by the National Nanotechnology Initiative (NNI), the Workshop will highlight new research on the tools and methods available to characterize and quantify effective population exposures, as well as the presence and release potential of nanomaterials. The two-day technical Workshop builds on key themes that emerged from the first QEEN workshop in 2015. According to NNI, the program will address the progress in integrating exposure, hazard, and risk to reduce uncertainties in nanomaterial environmental, health, and safety (EHS) assessments. The Workshop goals include the identification of priorities and options for cross-disciplinary research collaborations. NNI states that the intended audience includes academics, federal representatives, and manufacturers and distributors of nanotechnology-enabled products, as well as communities seeking to understand exposure science related to engineered nanomaterials. The Workshop is free and open to the public with registration on a first-come, first-served basis. Registration will open on July 9, 2018, and will be capped at 180 attendees. The 2018 U.S.-European Union (EU) “Bridging Nanotechnology EHS (NanoEHS) Research Efforts” joint workshop will also be held in Washington, D.C., on October 11-12, 2018. It will be the seventh event in a series of joint nanoEHS workshops organized by NNI and the European Commission (EC).
