Nanoparticle (NP) exposure poses health risks, particularly in the lungs, leading to toxicity. This review details NP lung toxicity mechanisms, including oxidative stress, DNA damage, and inflammation.

Area of Science:

  • Biomedical Nanotechnology
  • Toxicology
  • Pulmonary Medicine

Background:

  • Nanotechnology engineering has advanced biomedical applications.
  • Health and safety studies on nanomaterials, especially nanoparticles (NPs), are insufficient.
  • Occupational exposure to NPs is a significant health concern.

Purpose of the Study:

  • To review the health and safety aspects of nanomaterials in biomedical applications.
  • To highlight the lung toxicity associated with nanoparticle exposure.
  • To elucidate the mechanisms underlying pulmonary toxicity from NPs.

Main Methods:

  • Literature review of studies on nanoparticle lung toxicity.
  • Analysis of NP uptake by alveolar cells.
  • Examination of NP-induced cellular and tissue responses in the lungs.

Main Results:

  • Nanoparticles can enter the lungs and accumulate in alveolar spaces.
  • NP exposure can cause oxidative stress, DNA damage, and inflammation.
  • These effects may lead to lung fibrosis and pneumoconiosis.

Conclusions:

  • Nanoparticle exposure presents significant risks for lung health.
  • Understanding the mechanisms of pulmonary toxicity is crucial for risk assessment.
  • Further research is needed to ensure the safe application of nanomaterials.
