An extensive study of published research, commissioned by the EU Observatory for Nanomaterials, has raised major concerns over health risks caused by nano-sized pigments. It concluded that existing assessment techniques may not be able to properly identify the damage caused by these fabric colorants.
Its conclusion raises special concerns about inhaling nanoparticles, and their ability to enter the body and damage cells.
Industrial and professional workers handling “dry and free nanopigments which may become airborne present the highest concern,” it said.
The observatory warned of missing information on exposure, a dearth of reliable nano-specific toxicological data, and a general lack of public-domain data: “There should be an increased emphasis on exposure assessment and control.”
