This variable describes the uptake fraction of Di-n-butylphthalate when exposed through inhalation, ingestion or dermal pathway. Different uptake fractions for adults and children.



Data was obtained from couple of sources and is mainly based on measurements.






Dermal route (UFder) Inhalation route (UFinh) Oral route (UForal)
Adults 0.1 [1] 0.75 [2] Uniform, min = 0.5, max = 0.9 [1], [3]
Children 0.1 [1] 1 [2] Uniform, min = 0.5, max = 0.9 [1], [3]
