From: Distribution and persistence of pleural penetrations by multi-walled carbon nanotubes
Effect of MWCNT dose on MWCNT fiber penetrations into subpleural tissue and intrapleural space 56 days after aspiration. This figure shows the number per lung for fibers which penetrated into the subpleural tissue and for fibers which penetrated into the intrapleural space. As indicated by the asterisks, both the number of subpleural tissue and intrapleural space penetrations at 80 μg were different from the corresponding subpleural tissue and intrapleural space penetrations at doses of 10, 20 and 40 μg. (Mean ± SE, N = 8).
