For more information check the ICON results for "Exposure".
Inhalation of elemental carbon Ultra Fine Particles alters peripheral blood leukocyte distribution and expression of adhesion molecules, in a pattern consistent with increased retention of leukocytes in the pulmonary vascular bed. Particle exposure also reduced the percentage of CD4(+) T cells, basophils, and eosinophils. See the complete ICON abstract.
Toxicity of an engineered nanoparticle (fullerene, C(60)) in two aquatic species, Daphnia and fathead minnow. See the complete ICON abstract.
Our results show that aqueous C-60 suspensions prepared without using any polar organic solvent not only have no acute or subacute toxicity in rodents but they also protect their livers in a dose-dependent manner against free-radical damage. See the complete ICON abstract.
