Manifestation of Systemic Toxicity in Rats after a Short-Time Inhalation of Lead Oxide Nanoparticles
Outbred female rats were exposed to inhalation of lead oxide nanoparticle aerosol produced right then and there at a concentration of 1.30 ± 0.10 mg/m<sup>3</sup> during 5 days for 4 h a day in a nose-only setup. A control group of rats were sham-exposed in parallel under simila...
