Effects of subchronic inhalation exposure to carbon black nanoparticles in the nasal airways of laboratory rats
The nose can be an efficient filter for inhaled gases, vapours and particles that may be harmful to the lung. Nasal airways may also be targets for injury caused by inhaled toxicants. To investigate the nasal toxicity of carbon black nanoparticles (CB), rats were exposed to 0, 1, 7 or 50 mg/m? of high surface area CB (HSCB; primary particle size 17 nm; particle surface area 300 m?/g) for 6 h/day, ...
