2.1 Risks Associated with Nanoparticles
The growing incorporation of inorganic nanoparticles into consumer products raises legitimate questions about their potential health impacts. Inhalation, oral ingestion, and dermal exposure are the primary routes of exposure.
The risk from inhalation primarily affects individuals with occupational exposure to manufactured nanomaterials. However, the general population may be affected by the inhalation of ultrafine particles present in the atmosphere (cosmetic sprays, cleaning products, combustion soot, NOx, etc.). Due to their small size, NPs can settle in the respiratory tract, particularly in the pulmonary alveoli. They are then capable of crossing the epithelium and entering the pulmonary interstitium. There, they can cause inflammation and oxidative...
