These were analyzed for their content of Dimethyl Phthalate, Diethyl Phthalate, Di-n-butyl Phthalate , butyl benzyl Phthalate , bis(2-ethylhexyl) Phthalate ,and di-n-octyl Phthalate Mean concentrations (range) of Di(2-ethylhexyl) phthalate (DEHP), Butyl benzyl phthalate (BBP) and di- n-butyl phthalate (DBP) in fish samples were 1.1 ((less than)0.01-1.5), 0.22 ((less than)0.01-1.1) and 0.14 ((less than)0.01-1.3) (Mu)g g[?]1; those in shell fishery were 1.2 ((less than)0.02-1.3), 0.13 ((less than)0.01-0.27) and 0.09 ((less than)0.02-0.22) (Mu)g g[?]1, respectively.
Estimated mean adult intakes ranged from 0.004 [mu]g/kg/day for dimethyl phthalate (DMP) to 0.673 [mu]g/kg/day for DEHP.
Several different phthalates are currently used as excipients in approved pharmaceutical formulations: diethyl phthalate (DEP), dihutyl phthalate (DBP), dimethyl phthalate (DMP), dioctylphthalate (DOP), hypromellose phthalate (HMP), cellulose acetate phthalate (CAP), polyvinyl acetate phthalate (PVAP), and polyethylene terphthalate (PET) [Food and Drug Administration (FDA) 2010b].
This family of EDCs includes higher-molecular-weight phthalates such as bis(2-ethylhexyl) phthalate [DEHP; a common polyvinyl chloride (PVC) additive], dibutyl phthalate (DBP), and butyl benzyl phthalate (BBP), and also lower-molecular-weight phthalates such as dimethyl phthalate (DMP) and diethyl phthalate (DEP), which is commonly used as a solvent for fragrance.
Fruit consumption was associated with levels of MnMP, a metabolite of dimethyl phthalate, a low-molecular-weight phthalate.
