Eleven phthalate esters and di(2-ethylhexyl) adipate in one- week duplicate diet samples obtained from hospitals and their estimated daily intake

摘要

Plasticizers in duplicate diet samples obtained over 1 week were analysed in order to estimate daily intake. The phthalate esters we as follows: diethyl, dipropyl, Dibutyl, dipentyl, dihexyl, butylbenzyl, dicyclohexyl, Di(2-ethylhexyl), dioxtyl, diisooctyl (mixture of iso- Mers) and diisononyl (mixture). Di(2-ehtylhexyl) Adipate was also determined. Homogenized samples of Composite meals were extracted with acetonitrile, lipids Were removed by extraction into n-hexane and the Acetonitrile layer was cleaned using Florisil~R and Bondesil PSA~R dual layer column.
