Varner, K., G. Cobb, O. Tsyusko-Unrine, AND E. Petersen. Can You See What I See: Taking A Look At Nanoparticle Environmental Interactions. Session of the 2023 SETAC North America Annual Meeting, Louisville, KY, November 12 - 16, 2023.
Impact/Purpose:
The focus of this session is based on engineering factors to understand the transformation, transport, and longevity of the engineered nanomaterials. Fifteen years studying nanomaterials has enlightened many research areas such as environmental presence, concentration, and disposition, particle and toxicity characteristics and more. But for every question answered, many more are asked. In a similar fashion, products containing nanomaterials are increasing exponentially. Increasing products means more releases into the environment, highlighting the importance in understanding the potential environmental impacts, human effects, and safety risks of nanotechnology to ensure sustainable development in this area. It is important to understand the exposure, chemistry, and toxicology of nanomaterials released into the environment. This session would be of interest to the environmental community in general and specifically to our regional partners.
Description:
Over fifteen years studying nanomaterials has enlightened many research areas such as the environmental presence, concentration, and disposition, particle, and toxicity characteristics and more. But for every question answered, many more are asked. In a similar fashion, products containing nanomaterials are increasing exponentially, including food, medical and personal care products, fabrics, and paints/coatings. Increasing products means more releases into the environment, highlighting the importance in understanding the potential environmental impacts, human effects, and safety risks of nanotechnology to ensure sustainable development in this area. Accumulated knowledge needs to be assembled comprehensively to clearly understand nanomaterials, predict that which we do not know, and make informed decisions and regulations. This platform session aims to highlight recent research on nanomaterials in commerce and the environment. We anticipate this platform to have studies that address mechanisms and consequences of nanoparticle interactions and welcome investigations that focus on nanoparticle bioavailability, toxicity, and transformation of nanomaterials. We encourage submission of studies that consider aspects of realistic exposure scenarios along with the discussion of predicting and evaluating environmental and human health risk. Abstracts that focus on the identification of system parameters that alter the surface characteristics of nanomaterials through aggregation (e.g., pH effects), complexation (e.g., surface complexation by dissolved organic carbon), or changes in oxidation state (e.g., chemically, or biologically mediated electron transfer) are encouraged. Presentations and findings are welcomed on bioavailability uptake, measurement, monitoring, fate and transport (to elucidate the mechanisms), effects, health, and safety, which include predominate use in various fields, such as agriculture, nanotechnology, and sustainability of nanomaterials to ensure our sustained global future.
