Phthalates and bisphenol A (BPA) are plasticizers used in many industrial products that can act as endocrine disruptors and lead to metabolic diseases. During the LIFE PERSUADED project, we measured the urinary concentrations of BPA and Di(2-ethylhexyl)phthalate (DEHP) metabolites in 900 Italian women representative of the Italian female adult population (living in the north, centre, and south of Italy in both rural and urban areas). The whole cohort was exposed to DEHP and BPA with measurable levels above limit of detection in more than 99% and 95% of the samples, respectively. The exposure patterns differed for the two chemicals in the three macro-areas with the highest urinary levels for DEHP in south compared to central and northern Italy and for BPA in northern compared to central and southern Italy. BPA levels were higher in women living in urban areas, whereas no difference between areas was observed for DEHP. The estimated daily intake of BPA was 0.11 μg/kg per day, about 36-fold below the current temporary tolerable daily intake of 4 μg/kg per day established by the EFSA in 2015. The analysis of cumulative exposure showed a positive correlation between DEHP and BPA. Further, the reduction of exposure to DEHP and BPA, through specific legislative measures, is necessary to limit the harmfulness of these substances.
邻苯二甲酸酯和双酚 A(BPA)是许多工业产品中使用的增塑剂,它们可以作为内分泌干扰物,导致代谢疾病。在 LIFE PERSUADED 项目中,我们测量了 900 名意大利女性的尿液中 BPA 和邻苯二甲酸二(2-乙基己基)酯(DEHP)代谢物的浓度,这些女性代表了意大利成年女性人口(居住在意大利北部、中部和南部,包括农村和城市地区)。整个队列都接触到了 DEHP 和 BPA,在超过 99%和 95%的样本中,它们的测量水平都超过了检测限。在这三种宏观区域中,两种化学物质的暴露模式不同,DEHP 的尿液水平在南部最高,而在中部和北部较低;BPA 的尿液水平在北部最高,而在中部和南部较低。在城市地区居住的女性 BPA 水平较高,而 DEHP 则没有地区差异。BPA 的估计日摄入量为 0.11μg/kg/天,远低于 EFSA 在 2015 年制定的 4μg/kg/天的当前临时可耐受日摄入量。累积暴露分析显示 DEHP 和 BPA 之间存在正相关。此外,通过具体的立法措施减少 DEHP 和 BPA 的暴露,对于限制这些物质的危害性是必要的。
