TLDR
Results show that, for the test conditions described here and on an equal-weight basis, if carbon nanotubes reach the lungs, they are much more toxic than carbon black and can be more Toxic than quartz, which is considered a serious occupational health hazard in chronic inhalation exposures.About:

In vivo activation of a T helper 2-driven innate immune response in lung fibrosis induced by multi-walled carbon nanotubes.
TL;DR: This study uncovers activation of a Th2-driven immune/inflammatory response during pulmonary fibrosis development induced by MWCNT, providing novel insights into the molecular events that control the transition from an acute inflammatory response to chronic fibrosis through Th2 functions in CNT-exposed lungs.

Synthesis, characterization and cytotoxicity of phosphoryl choline-grafted water-soluble carbon nanotubes
TL;DR: In this paper, carbon nanotubes (CNTs) were rendered water-soluble by grafting on phosphoryl choline (PC), and the modified CNTs were characterized utilizing Fourier transform infrared spectra, X-ray photoelectron spectra and dynamic laser light-scattering.

TL;DR: The present studies with rats indicate that early granuloma formation does not lead to the development of mesotheliomas during chronic exposure of peritoneal Mesothelium to either single- or multi-walled carbon nanotubes of varied size.

Comparative pulmonary toxicity assessment of single-wall carbon nanotubes in rats.
TL;DR: Results from the lung histopathology component of the study indicated that pulmonary exposures to quartz particles produced dose-dependent inflammatory responses, concomitant with foamy alveolar macrophage accumulation and lung tissue thickening at the sites of normal particle deposition.

Exposure to carbon nanotube material: aerosol release during the handling of unrefined single-walled carbon nanotube material
Andrew D. Maynard,Paul A. Baron,Michael Foley,Anna A. Shvedova,Elena R. Kisin,Vincent Castranova +5 more
TL;DR: Although laboratory studies indicated that with sufficient agitation, unrefined SWCNT material can release fine particles into the air, concentrations generated while handling material in the field were very low, and estimates of the airborne concen-tration of nanotube material generated during handling suggest that concentrations were lower than 53μg/m3 in all cases.
