Phthalate acid esters (PAEs) are one of the essential plastic additives which may lead to plenty of harmful effects, including reproductive toxicity, teratogenicity, and carcinogenicity. Increasing attention has been paid to the migration of plasticizer. In this article, the disposable plastic lunch boxes were taken as the research object. The result showed that dibutyl phthalate (DBP) and diisobutyl phthalate (DIBP) have been mainly found, whose content was 1.5 mg/kg and 2.4 mg/kg, respectively. The LOD was 2 ng/g, and LOQ was 6.7 ng/g. We further investigated the migration of PAEs into the simulated liquid at different temperature conditions. Then, the linear fitting performing by first-order kinetic migration model revealed that the lower the polarity of the simulated liquid, the larger the rate constant and initial release rate . The higher the temperature, the bigger the and .
邻苯二甲酸酯（PAEs）是一类重要的塑料添加剂，可能会导致多种有害影响，包括生殖毒性、致畸性和致癌性。增塑剂的迁移问题日益受到关注。本文以一次性塑料饭盒为研究对象。结果表明，主要检测到邻苯二甲酸二丁酯（DBP）和邻苯二甲酸二异丁酯（DIBP），其含量分别为1.5毫克/千克和2.4毫克/千克。检测限为2纳克/克，定量限为6.7纳克/克。我们进一步研究了PAEs在不同温度条件下向模拟液体中的迁移情况。然后，通过一级动力学迁移模型进行线性拟合发现，模拟液体的极性越低，速率常数和初始释放速率越大。温度越高，和越大。
