Abstract
Many experimental measurements of steady-state dermal absorption rates of chemical compounds have been reported, and considerable progress has been made in the prediction of these rates. Most real-world dermal exposures, however, are not steady-state. Unfortunately, much less work has been devoted toward experimental and theoretical understanding of the transient dermal dose situation. Here we consider the following scenario: an amount of chemical is applied to the skin and removed a "short time" later, before significant depletion of the chemical has occurred. This scenario might be mimicked in the workplace, for example, where a worker splashes some chemical on his skin and effectively washes it some time later. Experiments were performed using in-vitro diffusion cells to measure the transient dose dermal absorption of diethyl phthalate. Theoretical predictions are compared with the experimental results as a demonstration of concept.
