Time course of in vitro dermal absorption of diethyl phthalate. Following a 40-min exposure (hashed box on time axis), the chemical was removed and skin was thoroughly rinsed. Absorption continues well after the exposure duration. Mass accumulation at 4 h (42 μg/cm2) was over three times more than that at 40 min (13 μg/cm2). Dashed line at 78 μg/cm2 represents the total absorbed amount predicted by Eq. (9).
