Guidance Document on Dermal Absorption
2 An overview of dermal absorption 2.1 Introduction The dermal absorption is one of the determining factors in assessment of the internal exposure of pesticide workers and operators. The establishment of a value for dermal absorption may be performed by use of a tiered approach from a worst case to a more refined estimate (De Heer 1999).
