- •
The accuracy of measuring lung deposited surface area concentrations has been assessed.
- •
Measurements were conducted with monodisperse particles between 10 nm and 700 nm.
- •
Highest accuracy around of ±30% or better for particle sizes between 20 nm and 400 nm.
- •
Concentrations of particles <20 nm are significantly overestimated.
- •
Concentrations of particles >400 nm are significantly underestimated.
