摘要: A three-year (2010-2012) survey was conducted to assess the prevalence and concentrations of deoxy-nivalenol (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 chromatogra-phy-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.
