(Bio)monitoring data
Yes, in human urine and breast milk.; Compared to urine, human breast milk contains relatively more of the hydrophobic phthalates, including di-iso-nonyl phthalate (DiNP) and their monoester metabolites.  In general, children have higher exposures compared to adults and seem to have a more effective oxidative metabolism of phthalates.;  In waste effluents, surface water, lake and river sediment.; In household dust.
