Several factors influence the level and type of exposure to nanomaterials:
1. Particle Size and Shape: Smaller particles have a higher surface area to volume ratio, which can increase their reactivity and potential for bioaccumulation. 2. Surface Chemistry: The chemical properties of the nanoparticle's surface can affect its interaction with biological systems. 3. Dosage and Duration: The amount and duration of exposure significantly impact the potential health effects. 4. Environmental Conditions: Factors like temperature, humidity, and the presence of other chemicals can influence the behavior of nanomaterials.
