Determination of plasticizer residues in tea by solid phase extraction–gas chromatography–mass spectrometry

摘要: Human exposure to plasticizers is widespread because these compounds are commonly found in the environment. Nevertheless, studies on human dietary limited. This research deals with evaluation of 27 plasticizer residues tea infusion samples brewed and without bag. Levels were determined by solid phase extraction–gas chromatography–mass spectrometry (SPE–GC–MS). Only a small number detected: di(2-ethylhexyl) phthalate (DEHP), di-n-butyl (DBP) DEP all analyzed samples, while di-methyl (DMP), bis-(2-ethylhexyl) adipate (DEHA) DiNP 80, 70 10 % them. Flavored teas showed higher DMP, DEHA DEHP residues, probably due use essential oils where accumulated. In addition, decaffeinated black DBP levels 18 times compared average other samples. The contents infused bag was almost always than those contribution that do not constitute risk for consumers.
