Several phthalate acid esters (PAEs), often called phthalate esters or phthalates, are substances classified as harmful due to their carcinogenic and mutagenic properties, and moreover, as dangerous for humans because they interfere with the endocrine system. In general, phthalic esters are used as plasticizers for different polymers and more other consumer products. In the present study, we describe a simple method to quantify PAEs in coffee brew using a liquid-liquid extraction without purification processes through analysing the obtained organic phase by GCMS in the single ion monitoring mode. The totals of single PAEs, in coffee brew samples analysed by us, are in the range of 159-5305 μg L . Considering that, on average, a person drinks three cups (total 90 mL) of the aforementioned drink per day, this will lead to the uptake of a total 14 to 477 μg of phthalates.
几种邻苯二甲酸酯（PAE），通常称为邻苯二甲酸酯或酞酸盐，由于其致癌和致突变特性而被归类为有害物质，此外，由于它们会干扰内分泌系统，因此对人类也很危险。一般来说，邻苯二甲酸酯被用作不同聚合物和更多其他消费产品的增塑剂。在本研究中，我们描述了一种简单的方法，可通过液 - 液萃取（无需纯化过程），使用 GCMS 在单离子监测模式下分析所得有机相，从而定量测定咖啡冲泡液中的邻苯二甲酸酯。通过我们分析的咖啡冲泡样品中的单邻苯二甲酸酯总量在 159-5305μg/L 的范围内。考虑到，一般情况下，一个人每天要喝三杯（共 90 毫升）上述饮品，这将导致摄入 14 到 477μg 的邻苯二甲酸盐。
