Exposomics analyses have highlighted the importance of biomonitoring of human exposure to pollutants, even non-persistent, for the prevention of non-communicable diseases such as obesity, diabetes, non-alcoholic fatty liver disease, atherosclerosis, and cardiovascular diseases. Phthalates and bisphenol A (BPA) are endocrine disrupting chemicals (EDCs) widely used in industry and in a large range of daily life products that increase the risk of endocrine and cardiometabolic diseases especially if the exposure starts during childhood. Thus, biomonitoring of exposure to these compounds is important not only in adulthood but also in childhood. This was the goal of the LIFE-PERSUADED project that measured the exposure to phthalates (DEHP metabolites, MEHP, MEHHP, MEOHP) and BPA in Italian mother–children couples of different ages. In this paper we describe the method that was set up for the LIFE PERSUADED project and validated during the proficiency test (ICI/EQUAS) showing that accurate determination of urinary phthalates and BPA can be achieved starting from small sample size (0.5 mL) using two MS techniques applied in cascade on the same deconjugated matrix.
曝露组学分析凸显了生物监测人类暴露于污染物的重要性,即使是非持久性的,以预防非传染性疾病,如肥胖症、糖尿病、非酒精性脂肪肝、动脉硬化和心血管疾病。邻苯二甲酸酯和双酚A(BPA)是一种广泛用于工业和日常生活产品中的内分泌干扰物质(EDC),如果暴露始于儿童期,会增加内分泌和心血管代谢疾病的风险。因此,这些化合物的暴露生物监测不仅在成年人中重要,而且在儿童中也很重要。这是LIFE-PERSUADED项目的目标,该项目测量了不同年龄的意大利母亲-儿童夫妇对邻苯二甲酸酯(DEHP代谢物,MEHP,MEHHP,MEOHP)和BPA的暴露。在本文中,我们描述了为LIFE PERSUADED项目设立并在ICI/EQUAS的熟练度测试中进行验证的方法,表明可以从小样本量(0.5 mL)开始使用两种串联的质谱技术在相同的脱共轭矩阵上实现准确测定尿中邻苯二甲酸酯和BPA。
