title: Formation of mono(ethylhexyl)phthalate from di(ethylhexyl)phthalate in human plasma stored in PVC bags and its presence in fractionated plasma proteins.
abstract: The formation of mono(ethylhexyl)phthalate (MEHP) from di(ethylhexyl)phthalate in human plasma stored in bags of polyvinylchloride has been studied. Substantial amounts were formed and in ten bags from 4 to 56microgram/ml were found. After 2 weeks at room temperature the concentration of MEHP had increased to values between 27 and 79 microgram/ml. However, MEHP was also disappearing as shown in a recovery experiment. Of the fractionated proteins albumin contained MEHP in amounts from less than 3 to 290 microgram/g.
