An exposure assessment of DUP, a high molecular weight phthalate plasticizer present in automobile upholstery, was conducted.
Oral exposures from hand-to-mouth contact were estimated represent 99% of all exposures.
The estimated daily absorbed doses were far lower than the reported NOAEL and DNEL values.
This approach can be applied to exposure assessment for other phthalates in consumer products.
The maximum oral intake dose was 0.01% of the human oral NOAEL dose for DUP.
