Twenty-seven mycotoxins in unprocessed cereals ( = 110) and pulses ( = 23) harvested in Latvia were analysed by nanoflow liquid chromatography combined with Orbitrap high-resolution mass spectrometry. One or more mycotoxins were found in 99% of the cereals and 78% of the pulses. Deoxynivalenol, zearalenone and T-2 and HT-2 toxins were prevalent in 9 to 86% of the cereals, mostly below their maximum levels as set by the European regulations. Non-regulated type A and B trichothecenes were prevalent in 5 to 87% of the cereals, at concentrations of 0.27-83 µg kg and 1.7-4,781 µg kg, respectively. Quantification of emerging mycotoxins was also provided. Enniatins were detected in 94% of the cereals (3.5-2,073 µg kg) and 13% of the pulses (4.4-17 µg kg). toxins were prevalent in 94% of the cereals at concentrations of 0.72-307 µg kg and in 39% of the pulses at 0.69-10 µg kg.
采用纳流液相色谱结合轨道阱高分辨率质谱法，对拉脱维亚收获的未加工谷物（n = 110）和豆类（n = 23）中的27种霉菌毒素进行了分析。在99%的谷物和78%的豆类中发现了一种或多种霉菌毒素。脱氧雪腐镰刀菌烯醇、玉米赤霉烯酮以及T-2毒素和HT-2毒素在9%至86%的谷物中普遍存在，大多低于欧洲法规设定的最高限量。未受监管的A类和B类单端孢霉烯族毒素在5%至87%的谷物中普遍存在，浓度分别为0.27 - 83 μg/kg和1.7 - 4781 μg/kg。还提供了新出现霉菌毒素的定量分析结果。在94%的谷物（3.5 - 2073 μg/kg）和13%的豆类（4.4 - 17 μg/kg）中检测到恩镰孢菌素。 毒素在94%的谷物中普遍存在，浓度为0.72 - 307 μg/kg，在39%的豆类中浓度为0.69 - 10 μg/kg。
