Abstract

In this study, a pyrolysis-gas chromatography/mass spectrometry method was established to quantify microplastics (MPs) released from plastic food containers during rinsing and migration. The inner surface of actual samples was rinsed with deionized water, and the MPs in rinse water were collected through a glass fiber membrane with pore size of 1 μm. Subsequently, thoroughly cleaned polypropylene (PP) food packaging containers were selected for migration tests under different simulants, migration temperatures, and migration times. It was found that MPs corresponding to the materials of product manufacture were detected in all collected containers during rinsing. By migration tests, the results showed that high-fat foods, high/low temperature (5 °C), and long exposure periods can promote the release of MPs. It was also proved that the migration of MPs from plastic food containers was one of the important sources for human exposure to MPs. The obtained results can provide evidence for the safety risk assessment of plastic food containers.

用热解-气相色谱/质谱法定量分析塑料食品容器在漂洗和迁移过程中释放的微塑料

本研究建立了一种热解-气相色谱/质谱联用方法来定量塑料食品容器在漂洗和迁移过程中释放的微塑料（MPs）。用去离子水冲洗实际样品的内表面，用孔径为1 μm的玻璃纤维膜收集冲洗水中的MPs。随后，选择彻底清洗过的聚丙烯（PP）食品包装容器，在不同模拟剂、迁移温度和迁移时间下进行迁移测试。发现在所有收集的容器中都检测到与产品制造材料相对应的MPs。通过迁移试验，结果表明，高脂肪食物、高/低温（5 °C）和长时间暴露可促进MPs的释放。研究还证明，塑料食品容器中多磺酸盐的迁移是人体暴露于多磺酸盐的重要来源之一。所得结果可为塑料食品容器的安全风险评价提供依据。
