The use of nanomaterials (NMs) and devices is an active area of research and development in the semiconductor and advanced electronics industries and increasingly finding applications in products and processes. Due to their increased usage in R&D and manufacturing, there is a need to ensure that these novel nanomaterials are adequately assessed to ensure protection of worker and consumer health and protection of the environment. These chemical substances may have properties different than the same chemical substances with structures at a larger scale, such as greater strength, lighter weight, and greater chemical reactivity. These enhanced or different properties give nanoscale materials a range of potentially beneficial public and commercial applications; however, the same special properties may cause some of these chemical substances to behave differently than conventional chemicals under specific conditions. These unique properties of NMs require special considerations for the their safety assessments throughout the lifecycle that translate into specific requirements for hazards assessments for new chemical registrations, management of workplace exposure prevention and end of life waste disposal and recycling requirements. This roundtable will discuss important issues to consider for the safe use of nanomaterials throughout the lifecycle. The views will be presented from four experts in the science, toxicology, industrial hygiene and lifecycle practices for nanomaterials. Each will provide a brief introduction to these four topical areas and join in a roundtable discussion with the audience. Dr. Rowlands will discuss the Health and environmental hazard assessment of nanomaterials. The enhanced and unique properties that provide nanomaterials a range of potentially beneficial public and commercial applications; however, the same special properties may cause some of these chemical substances to behave differently than conventional chemicals under specific conditions. The current approaches and challenges to toxicity testing of nanomaterials for human health and environmental safety will be described.
