Abstract

A three-year (2010-2012) survey was conducted to assess the prevalence and concentrations of deoxynivalenol (DON) and zearalenone (ZEN) in wheat from several regions of Jiangsu province, China, which are heavily impacted by Fusarium head blight. A total of 180 wheat samples were obtained from the infected fields that spread 21 counties. DON and ZEN levels were determined by liquid chromatography-mass spectrometry (LC-MS/MS). DON was found in 74.4% of samples at levels ranging from 14.52 to 41157.13 μg/kg (mean 488.02 μg/kg), while ZEN was found in 12.8% of samples at levels ranging from 10.13 to 3048.88 μg/kg (mean 73.04 μg/kg). In years and regions of higher rainfall, DON and ZEN levels were higher in samples. These results are necessary to take a vigilant attitude to prevent human intake of trichothecenes and protect human's health from the risk of exposure to these toxins.

摘要

开展了一项为期三年（2010 - 2012年）的调查，以评估中国江苏省几个受赤霉病严重影响地区小麦中脱氧雪腐镰刀菌烯醇（DON）和玉米赤霉烯酮（ZEN）的污染率及含量。从分布于21个县的感染田块共采集了180份小麦样品。采用液相色谱 - 质谱联用仪（LC - MS/MS）测定DON和ZEN含量。在74.4%的样品中检测到DON，含量范围为14.52至41157.13μg/kg（平均488.02μg/kg），而在12.8%的样品中检测到ZEN，含量范围为10.13至3048.88μg/kg（平均73.04μg/kg）。在降雨较多的年份和地区，样品中的DON和ZEN含量较高。这些结果对于人们警惕摄入单端孢霉烯族毒素并保护人体健康免受这些毒素暴露风险具有重要意义。
