Step 2.1 Estimating Exposure Doses

bullet Estimating a Dermal Contact Dose: When and How?

When? Dermal contact doses should be estimated

*

when the chemical being evaluated is one that can pass through a person's skin

 

or

*

when most of the skin on a person's body is exposed to a chemical; for example, while swimming.

How? Dermal contact doses are estimated as follows.

dose=

*

where,

 
*

the intake rate for dermal contact with chemicals in water = (the area of skin exposed × the chemical-specific permeability constant)

 

or

*

the intake rate for dermal contact with chemicals in soil = (the area of skin exposed × soil adherence factor × chemical-specific bioavailability factor)
