Workers can be exposed to nanomaterials through various routes:
Inhalation: The most common route, where nanoparticles are inhaled and deposited in the respiratory tract. Dermal Contact: Nanoparticles can penetrate the skin, especially if it is damaged or compromised. Ingestion: Accidental ingestion can occur through contaminated hands or surfaces. Injection: Though less common, exposure can occur through accidental needle sticks or other breaches in the skin.
