Exposure to nanomaterials can occur through several pathways:
Inhalation: Nanoparticles can become airborne during production or usage and can be inhaled, entering the respiratory system. Dermal Contact: Direct contact with skin can happen when handling nanomaterials. Ingestion: Accidental ingestion can occur if nanoparticles contaminate food or through hand-to-mouth activities. Environmental Exposure: Nanomaterials can enter the environment through waste streams, potentially affecting soil, water, and air quality.
