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:

Responses of soil ammonia-oxidizing microorganisms to repeated exposure of single-walled and multi-walled carbon nanotubes.
TL;DR: Two-way ANOVA analysis showed that CNTs had significant effects on the abundance and diversity of AOB and AOA, and implied that AOB prefer for high-NH4(+) soils whereas AOA is favored in low NH4(+ soils in the CNT-contaminated soil.

Increased Adsorption of Heavy Metal Ions in Multi-Walled Carbon Nanotubes with Improved Dispersion Stability.
TL;DR: Test the effect of dispersion of oxidized multi-walled carbon nanotubes (MWCNTs) on the removal of heavy metals from acidic solutions and finds that kinetic experiments showed a faster saturation on MWCNTs in column experiments, which contribute to a better understanding of the effect on the use of CNTs as heavy metal ions adsorbent.

TL;DR: Results indicated that reduction in humic substances and chemical structure variation might be the important reason attributed to the MWCNTs toxicity, referring to significant decrease in combined Cd contents.

Assessment of pulmonary toxicity of MgO nanoparticles in rats
TL;DR: MgO NPs exposure produced a dose‐dependent pulmonary toxicity in rats and was comparable with that of Quartz particles, indicating the pulmonary toxicity of MgONPs.

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.

TL;DR: A readily scalable purification process capable of handling single-wall carbon nanotube (SWNT) material in large batches, which should greatly facilitate investigation of material properties intrinsic to the nanotubes.

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.
