On December 17, 2019, the CDC National Institute for Occupational Safety and Health (NIOSH) issued a Federal Register Notice requesting the submission of toxicological and physicochemical data on Engineered Nanomaterials (ENMs). ENMs are substances manufactured by man for specific uses in medicine, manufacturing and food packaging. Nanoscale materials have at least one dimension in the range of 1 to 100 nanometers. A nanometer is approximately 100,000 times smaller than the diameter of a human hair. There is little data on the long-term biological effects of ENMs. NIOSH will use the submitted data in an evaluation of possible adverse health risks from occupational exposure to ENMs. Data are sought on dose-response relationships and adverse lung effects from contact with ENMs that can lead to the creation of categorical occupational exposure limits (OELs). NIOSH will publish a Technical Report which will describe the data, methods and findings – Summarized by Jack Cooper JLC@adfpi.org and Matt Farrell mf9895a@alumni.american.edu of the Animal Digestible Food Packaging Initiative https://adfpi.org/category/news/ - #SingleUsePlastics #FoodPackaging #PlasticWaste #PlasticPackaging #MicroPlastic #NanoPlastic
