中文摘要：2014年，10个国家的18个实验室参与了两个水平测试(PTs)：同时检测玉米中的脱氧雪腐镰刀菌烯醇、伏马菌素B1和B2、玉米赤霉烯酮、T-2及HT-2毒素、赭曲霉素A和黄曲霉毒素B1、B2、G1和G2以及小麦中的脱氧雪腐镰刀菌烯醇、玉米赤霉烯酮、T-2及HT-2毒素、赭曲霉素A。PTs的目的是检查参与者对LC–MS法的实验室性能外，用于检测多种霉菌毒素的现状。此外，还通过比较2011-2014年间组织的三次PTs评估了LC–MS法检测玉米中多种霉菌毒素的性能趋势及方法的相关问题。数据显示，实验室性能的改进为：总体上可接受的Z值从2011年的59%递增到2014年的85%，而不可接受的Z值比率则从2011年的25%下降到2014年的11%。
外文摘要：Two Proficiency Testings (PTs) involving eighteen laboratory participants from 10 Countries have been conducted in 2014 for the simultaneous determination of deoxynivalenol, fumonisins B1 and B2, zearalenone, T-2 and HT-2 toxins, ochratoxin A and aflatoxins B1, B2, G1 and G2 in maize and of deoxynivalenol, zearalenone, T-2 and HT-2 toxins and ochratoxin A in wheat, respectively. The aim of PTs was to check next to the laboratory performance the state-of-art of the LC–MS multi-mycotoxin methods used by participants. In addition, the trend of performances of LC–MS methods for multi-mycotoxin determination in maize together with method-related issues was assessed by comparing three PTs organised over the years 2011–2014. Data showed the improvement of laboratory performances with the overall acceptable z-scores that progressively increased from 59% in 2011 PT to 85% in 2014 PT, while the rate of unacceptable z-score decreased from 25% in 2011 PT to 11% in 2014 PT.
