Because of global warming and changes in farming systems, Fusarium head blight has gradually spread towards high-latitude regions such as Northwestern China. A survey was conducted to assess the prevalence and concentration of deoxynivalenol (DON) in wheat harvested during 2013 from the Shaanxi, Ningxia, Gansu, and Xinjiang provinces in China. DON concentration in 181 wheat samples was analysed by high-performance liquid chromatography combined with ultraviolet detection. Of the wheat samples, 82.9% were contaminated with DON, with a mean DON concentration of 500 μg/kg. According to the Chinese standard limits for DON, 10% of the positive samples were above the maximum limit of 1000 μg/kg. Regions with higher humidity showed higher levels of DON in the wheat samples. These results show the necessity of raising awareness of DON contamination in people from Northwestern China to protect their health from the risk of exposure to DON.
由于全球变暖和耕作制度的变化，小麦赤霉病已逐渐向中国西北等高纬度地区蔓延。本研究对2013年中国陕西、宁夏、甘肃和新疆四省收获小麦中脱氧雪腐镰刀菌烯醇（DON）的污染情况和含量水平进行了调查。采用高效液相色谱-紫外检测法对181份小麦样品中的DON含量进行了分析。结果显示，82.9%的小麦样品被DON污染，平均含量为500μg/kg。按照中国DON限量标准，10%的阳性样品超过最大限量1000μg/kg。湿度较高地区的小麦样品中DON含量较高。这些结果表明，有必要提高中国西北地区人们对DON污染的认识，以保护他们的健康免受DON暴露风险的影响。
