Bisphenol A (BPA) is one of the most common industrial chemicals and known to exert endocrine disruption activity. The aim of this study was the quantification of BPA in food stuffs on the Greek market. The applied liquid chromatography-mass spectrometry method was validated for linearity, limit of quantification, accuracy, precision and recovery. About 41.7% of the canned solid phase samples, 25.0% of the canned liquid phase samples and 43.8% of the soft drinks were positive. Mean BPA concentrations (range) were 33.4 ± 4.4 ng/g (4.90 ± 0.64-66.0 ± 8.6 ng/g) in canned solid phase, 2.70 ± 0.08 ng/ml (1.90 ± 0.06-3.50 ± 0.11 ng/ml) in canned liquid phase and 2.30 ± 0.18 ng/ml (0.40 ± 0.03-10.2 ± 0.8 ng/ml) in soft drinks. The results of this study are comparable with those reported in the literature according to which higher concentrations of BPA were detected in the solid fraction of canned food compared to their liquid fraction.
双酚A（BPA）是最常见的工业化学品之一，已知具有内分泌干扰活性。本研究的目的是对希腊市场上食品中的双酚A进行定量分析。所应用的液相色谱 - 质谱法在线性、定量限、准确度、精密度和回收率方面进行了验证。约41.7%的罐装固相样品、25.0%的罐装液相样品和43.8%的软饮料呈阳性。罐装固相中的双酚A平均浓度（范围）为33.4±4.4纳克/克（4.90±0.64 - 66.0±8.6纳克/克），罐装液相中为2.70±0.08纳克/毫升（1.90±0.06 - 3.50±0.11纳克/毫升），软饮料中为2.30±0.18纳克/毫升（0.40±0.03 - 10.2±0.8纳克/毫升）。本研究结果与文献报道的结果具有可比性，根据文献，罐装食品的固相部分中检测到的双酚A浓度高于其液相部分。
