Scientists investigating the effects of nanoparticles on blood vessels have presented evidence to suggest such toxicants can alter normal vessel function in animals, following preliminary research presented at the annual meeting of the Society of Toxicology on 13 March 2012.
Researchers from the Center for Cardiovascular and Respiratory Sciences at West Virginia University presented several abstracts, including evidence indicating that airborne titanium dioxide nanoparticle exposure may subsequently inhibit blood flow to muscles in rodents.
Exposure to carbon nanotubes were shown to have a similar effect. Further evidence suggested that vessel impairments are not limited to nanoparticle exposure via inhalation, but may also occur when nanoparticles are ingested via the diet.
