Implication

Toxicological review reveals severe pulmonary inflammation, fibrosis, and cardiovascular damage in rodent models exposed to carbon nanotubes, highlighting significant occupational inhalation risks.

Key Points

To evaluate experimental evidence regarding the pulmonary and systemic toxicity of single-wall and multi-wall carbon nanotubes and assess potential occupational and environmental inhalation risks.
Reviewed rodent studies evaluating pulmonary responses following intratracheal or intrapharyngeal administration of manufactured single-wall (SWCNTs) and multi-wall carbon nanotubes (MWCNTs).
Assessed comparative pulmonary toxicity relative to reference occupational hazards, specifically quartz dust and ultrafine carbon black.
Examined in vitro toxicity biomarkers in CNT-exposed skin cell cultures and analyzed environmental exposure data concerning combustion-generated MWCNTs in fine particulate matter.
SWCNTs and MWCNTs consistently induced pulmonary inflammation, epithelioid granulomas, fibrosis, and biochemical toxicological changes in rodent lungs regardless of synthesis method or metal content.
SWCNTs demonstrated greater pulmonary toxicity than equivalent mass doses of quartz, whereas ultrafine carbon black elicited minimal lung responses.
Pulmonary exposure to SWCNTs impaired bacterial clearance and produced systemic vascular toxicities, including aortic mitochondrial DNA damage and enhanced atherosclerotic plaque formation.
