Extraction and gas chromatographic evaluation of plasticizers
The average extraction yield was 95 ± 10%. The chromatographic analysis was able to determine 16 different compounds, clearly separated, taking only 25 min to complete the assay. The detection limits ranged from 0.07 to 0.7% (w/w). The total amount of plasticizers in the packaging products was comprised between 3 and 10% (w/w).
Extraction and gas chromatographic evaluation of plasticizers
In all cases, the total amount of extracted plastic constituents reached the maximum value of 10% (w/w), lower than that reported in literature (about the 30%) as the amount necessary to obtain films with the required characteristics of adhesiveness and extensibility [29].

Determination of plasticizer residues in tea by solid phase
to plasticizers are limited. This research deals with the evaluation of 27 plasticizer residues in tea infusion samples brewed with and without bag. Levels were determined by solid phase extraction–gas chromatography–mass spec-trometry (SPE–GC–MS). Only a small number of plasti-cizer were detected: di(2-ethylhexyl) phthalate (DEHP),
Determination of plasticizer residues in tea by solid phase
Nevertheless, studies on human dietary exposure to plasticizers are limited. This research deals with the evaluation of 27 plasticizer residues in tea infusion samples brewed with and without bag. Levels were determined by solid phase extraction–gas chromatography–mass spectrometry (SPE–GC–MS).
