Step 2.1 Estimating Exposure Doses

An Inhalation Dose

No dose calculation is needed for an inhalation dose.

Why?

For inhalation doses, the amount of a chemical that is in the air is considered to be the amount that enters the lungs when a person breathes. Therefore, the amount of the chemical measured in the air is the inhalation dose.

Dermal contact dose

Dose calculation is rarely needed for dermal contact, but health assessors may calculate dermal contact doses if site-specific conditions warrant or if community concerns are involved.

From the following list of site-specific circumstances, determine which two that you consider would not require an estimate for a dermal contact dose.

For an adult who picks up a lead pipe
For an adult who occasionally touches soil that contains arsenic
For a baby who has been bathed daily in well water found to contain a pesticide
