RISK ASSESSMENT FOR MANUFACTURED NANOPARTICLES USED IN CONSUMER PRODUCTS (RAMNUC)
Impact/Purpose:
The overall hypothesis of the RAMNUC project is that MNPs at the point of exposure for both humans and aquatic animals will substantially differ in both physicochemical and toxicological properties from MNPs at the source (synthesized in the laboratory or acquired commercially). These differences may have significant consequences with respect to MNPs’ bioavailability, alterations of immunity, induction of oxidative stress, inflammation, disease processes, and other toxicity measures.
Description:
Most recent scientific efforts have focused on examining toxicities of manufactured nano-particles (MNPs) only in source materials. By not evaluating MNPs at the point of exposure, these efforts fail to address the relevant question of whether or not consumer-product-derived MNPs are of concern to public health and the environment. The proposed US-UK consortium, ‘Risk Assessment for Manufactured Nanoparticles Used in Consumer Products (RAMNUC)’, provides a systematic, multidisciplinary approach, including both experimental and computational tools and projects, for predicting potential human and environmental risks associated with the use of selected consumer products that respectively incorporate zinc oxide, silver, and cerium dioxide nanoparticles.
