2. How do nanomaterials enter the body?
Several penetration routes are possible: pulmonary, cutaneous and digestive.
2.1 Pulmonary penetration
Particulate nanomaterials are deposited in the pulmonary tract by the same process as micrometric particles. However, their aerodynamic behavior does not follow the laws that govern micrometric particles (see Absorption-Distribution-Metabolization-Excretion (ADME): how does a chemical substance circulate in the body?
