A scoping study to identify hazard data needs for addressing the risks presented by nanoparticles and nanotubes

This study examines methodologies for examining the toxicology, ecotoxicology, persistence and bioaccumulation potential for manufactured unfixed nanoparticles and nanotubes, the differences in hazard posed by variations in nanoparticle size and chemical composition, and how nanoparticles and nanotubes interact with cells and tissues in organisms. Based on their findings, the report makes recommendations as to where future research is needed, and the need for the standardization of protocols, measurements, and the development of a panel of well-characterized nanoparticles for research.
