Determination of the Migration of Polycyclic Aromatic Hydrocarbons in Four Kinds of Food Contact Materials

A method was established for the analysis of 16 kinds of the polycyclic aromatic hydrocarbons migration in food contact materials by GC-MS. Basing on the actural conditions of use,the sample was taken isooctane as the migration simulation and immersed,analyzed by GC-MS. As the results,there were 4 kinds of PAHs(naphthalene,phenanthrene,fluoranthene and pyrene)had a certain migration exposure level,in the food contact materials and the positive detection rate was 24.3%(naphthalene),77.1%(phenanthrene),48.6%(fluoranthene),44.3%(pyrene). And migration level of food contact container was up to 33545 ng/kg(phenanthrene),46296 ng/kg(phenanthrene),17739 ng/kg(fluoranthene),15594 ng/kg(pyrene),which was found that there was a positive correlation between the dissolution of evaporative residue(hexane)and the dissolution of polycyclic aromatic hydrocarbons. The four kinds of detected PAHs(naphthalene,phenanthrene,fluoranthene and pyrene)had a average recovery between 76.5% and 100.7%,the RSD between 1.0% and 3.5%,this method showed that a good level of accuracy and precision.
