中文摘要：本研究中，从巴伦西亚市当地不同的超市中购得80份商业面包样品，调查其中霉菌毒素是否超标。结果发现这些样品中黄曲霉毒素(AFs)、玉米赤霉烯酮 (ZEA)及恩镰孢菌素(ENs)的检出率分别为20%、96%和65%。受黄曲霉毒素B1污染的样品其毒素含量超过了欧盟最大限量；总黄曲霉毒素超限的样品有6个；恩镰孢菌素的存在最普遍；30%受ZEN污染的样品毒素含量超限。最后，通过商业面包的消费量及面包受污染程度，估算检测到的每种霉菌毒素的每日摄入量（EDI），从而评估巴伦西亚市民膳食受AFs、ENs和ZEA毒素暴露的情况。
外文摘要：In this study, 80 commercial samples of bread loaves were purchased from different supermarkets located in Valencia (Spain). These samples were investigated for the presence of legislated and non-legislated mycotoxins. Results showed that samples were contaminated with Aflatoxins (AFs), Zearalenone (ZEA) and Enniatins (ENs) with a frequency of 20, 96, and 65% respectively. Aflatoxin B1 (AFB1), Aflatoxin B2 (AFB2) and Aflatoxin G1 (AFG1) were detected with concentrations ranged from 0.5 to 7.1 μg/kg. The samples contaminated with AFB1 showed values exceeding the maximum limit allowed in the EU. The sum of AFs also exceeded the maximum limit allowed in 6 samples. ENs contamination data ranged from 0.2 to 54 μg/kg and ENB was the most prevalent one. ZEA values ranged from 27 to 905 μg/kg and 30% of the contaminated samples were above the limits enforced by the EU. Finally, dietary exposure of the population living in Valencia to AFs, ENs and ZEA was estimated using the deterministic approach, through the evaluation of the consumption of commercial loaf bread and relating this data with the contamination of the loaf bread, for the calculation of the estimated daily intake (EDI) for each mycotoxin detected.
