The contamination level of T-2 and HT-2 toxin in cereal crops from Aba area in Sichuan Province of China was investigated by rapid liquid chromatography-tandem mass spectrometry (HPLC-MS/MS). The results revealed the high incidence of T-2 and HT-2 toxin and relatively low contamination level in the samples. The incidence of HT-2 toxin was 49.74% and its average level was 3.746 μg/kg. The incidence of toxin was 11.64% and the average level was 0.565 μg/kg. The maximum of T-2 and HT-2 toxin concentration was 3.332 and 34.510 μg/kg, respectively. In addition, contaminated samples not only included homegrown products, but included external purchased rice and flour, which may be attributed to bad storage environment and sanitary conditions.
采用快速液相色谱-串联质谱法（HPLC-MS/MS）对中国四川省阿坝地区谷物作物中 T-2 和 HT-2 毒素的污染水平进行了调查。结果表明，样品中 T-2 和 HT-2 毒素的发生率较高，污染水平相对较低。HT-2 毒素的发生率为 49.74%，平均水平为 3.746μg/kg。毒素的发生率为 11.64%，平均水平为 0.565μg/kg。T-2 和 HT-2 毒素浓度的最大值分别为 3.332μg/kg 和 34.510μg/kg。此外，受污染的样品不仅包括国产产品，还包括外部购买的大米和面粉，这可能归因于恶劣的储存环境和卫生条件。
