Session abstract

Engineered nanomaterials are becoming increasingly relevant for regulatory scrutiny for two reasons: the EC definition of nanomaterials forced industries to identify conventional particulate materials with production volumes above 100,000 tons/year as nanomaterials, and consequently to re-evaluate their safe production, use and disposal. Additionally, innovative nanomaterials continue to enter the markets in many areas. There is still considerable uncertainty on risk for environmental and human safety because of the diversity of nanotechnology over many substances, applications and products.

Tools for identifying risk are currently of high interest for regulators, industries, and scientific community.  In the section, “Physicochemical characterization requirements and methods for grouping and risk assessment”, our speakers will review phys-chem properties of nanomaterials, appropriate methods, and implementation in tools for grouping and risk assessment.
