Evaluation of heavy metal migration from plastic food packaging materials to aqueous simulants by ICP-MS

Introduction

Heavy metal migration from different types of plastic food packaging materials was studied. The packaging materials were immersed into several mimic food solutions according to EU legislation to simulate the process of heavy metal migration onto foodstuffs. The concentrations of 14 metallic elements in aqueous simulants were accurately determined by the developed ICP-MS method. The migration of elements was observed to increase with contact time. The presence of heavy metals, especially toxic elements such as Pb, highlighted the importance of quality control measures for food packaging materials.
