Environment is polluted by airborne nanoparticles, unintentionally released by high
temperature combustive processes.
Results of the research
Ni Group : nodules observed on both
sides (particles + bulk material) in all animals 6
months after implantation
Co Group : Nodules observed on the left side (nanoparticles IM) in all
cases 8 months after implantation
– nothing on the right side (bulk material implanted SC)
FP5- European Project
NANOPATHOLOGY
Nickel and Cobalt nanoparticles induced rabdomiosarcoma after 6-month
implantation in rats, the bulk samples only fibrotic capsules or
granulomas.
