Inhaled Carbon Nanotubes Reach the SubPleural Tissue in Mice
Carbon nanotubes have fibrelike shape1 and stimulate inflammation at the surface of the peritoneum when injected into the abdominal cavity of mice2, raising concerns that inhaled nanotubes3 may cause pleural fibrosis and/or we show that multiwalled carbon nanotubes reach the subpleura in mice after a single inhalation exposure of 30 mg/m 3 for 6 hours.
