对盐城自然保护区丹顶鹤食物中真菌毒素的含量进行了调查。在2013年至2015年的越冬期间，在保护区的核心区，缓冲区和实验区收集了113个食品样品，使用高效液相色谱法（HPLC）分析了黄曲霉毒素B-1，脱氧雪腐镰刀菌烯醇，玉米赤霉烯酮，T-2毒素和赭曲霉毒素A。不同地区的污染率不同，不同食物样本的霉菌毒素水平也存在差异。稻谷中霉菌毒素的平均浓度高于其他食物。在真菌毒素阳性样本中，59.3%同时被一种以上的毒素污染。本研究首次证实了盐城生物圈保护区丹顶鹤暴露于真菌毒素，并提示人工湿地不适合丹顶鹤栖息，特别是稻田。
A survey was conducted to determine whether mycotoxins were present in the foods consumed by red-crowned cranes (Grus japonensis) in the Yancheng Biosphere Reserve, China. Collected in the reserve's core, buffer, and experimental zones during overwintering periods of 2013 to 2015, a total of 113 food samples were analyzed for aflatoxin B-1, deoxynivalenol, zearalenone, T-2 toxin, and ochratoxin A using high performance liquid chromatography (HPLC). The contamination incidences vary among different zones and the mycotoxins levels of different food samples also presented disparity. Average mycotoxin concentration from rice grain was greater than that from other food types. Among mycotoxin-positive samples, 59.3% were simultaneously contaminated with more than one toxin. This study demonstrated for the first time that red-crowned cranes were exposed to mycotoxins in the Yancheng Biosphere Reserve and suggested that artificial wetlands could not be considered good habitats for the birds in this reserve, especially rice fields.
