The monitoring of the contamination levels of bisphenol A (BPA) and its congeners bisphenol B (BPB) and bisphenol F (BPF) in foodstuffs is a necessary process for assessment of consumers' risk. After development and validation of a method using Strata® C18-E cartridge cleanup with detection by liquid chromatography coupled to tandem mass spectrometry, forty-six samples of fruit juices, sold on Italian markets, have been analysed to assess the concentration of BPA, BPB and BPF. BPB and BPF were not detected in any samples, BPA was found in 33 % of the samples. The observed levels ranged from 0.50 ng mL to 2.85 ng mL. Potential Daily Intakes (PDI) of BPA for Italian populations were calculated by the budget method model. PDIs ranged from 0.012 to 0.285 μg kg bw day. None of the calculated values exceeded the current temporary TDI of 4 μg kg bw day.
监测食品中双酚 A（BPA）及其同系物双酚 B（BPB）和双酚 F（BPF）的污染水平是评估消费者风险的必要过程。在使用 Strata® C18-E 柱净化并通过液相色谱-串联质谱检测方法开发和验证后，对意大利市场上销售的 46 份果汁样品进行了分析，以评估 BPA、BPB 和 BPF 的浓度。在任何样品中均未检测到 BPB 和 BPF，在 33%的样品中检测到 BPA。观察到的水平范围为 0.50ng/mL 至 2.85ng/mL。通过预算法模型计算了意大利人群的 BPA 潜在每日摄入量（PDI）。PDI 范围为 0.012 至 0.285μg/kg bw day。计算出的数值均未超过当前 4μg/kg bw day 的临时 TDI。
