    摘要:

    目的 了解黑龙江省玉米真菌毒素污染状况,分析污染原因以及提出防治措施。方法 采集黑龙江省各地玉米样品473份,对玉米样品中黄曲霉毒素(aflatoxins,Afs)、伏马毒素(fumonisins, FBs)、脱氧雪腐镰刀菌烯醇(deoxynivalenol, DON)及其代谢物、玉米赤霉烯酮(zearalenone, ZEN)、赭曲霉毒素A(ochratoxin A,OTA)、交链孢酚(alternariol, AOH)、交链孢酚单甲醚(alternariol monomethyl ether ,AME)、腾毒素(tentoxin, TEN)、交链孢菌酮酸(tenuazonic Acid, TeA)等16种真菌毒素进行检测,采用超高效液相色谱串联质谱同位素内标法检测和定量。 结果 玉米样品全部检出真菌毒素,检出率100%,每份样品受到一种及多种毒素共同污染;16种真菌毒素检出率范围为0.21%~98.31%;平均污染水平从0.67μ g/kg~259.19μ g/kg不等;3种毒素存在超标,超标率分别为脱氧雪腐镰刀菌烯醇(2.54%,12/473)、玉米赤霉烯酮(4.02%,19/473)和伏马毒素(2.54%,12/473);超标样本地区分布在牡丹江、双鸭山、鸡西、哈尔滨和齐齐哈尔。 结论 黑龙江省玉米受到多种真菌毒素联合污染,需要从多个环节加强监测以及采用多种途径和控制措施降低玉米污染。

    Abstract:

    Objective To understand the situation of corn mycotoxins contamination in Heilongjiang Province , and to analyze the causes of pollution and propose prevention and control measures. Methods Among the 473 corn samples were collected from various regions in Heilongjiang Province , and 16 mycotoxins , including aflatoxins , fumonisins, deoxynivalenol and their metabolites , zearalenone , ochratoxin A , alternariol , alternariol monomethyl ether , tentoxin , and tenuazonic acid , were detected in the corn samples. The detection and quantification were carried out using ultra-high performance liquid chromatography tandem mass spectrometry isotope internal standard method. Results All samples were detected with mycotoxins, the detection rate was 100%, and each sample was contaminated by one or more mycotoxins. The detection rate of 16 mycotoxins ranged from 0.21% to 98.31%. The average contamination level ranged from 0.67 μ g/kg-259.19 μ g/kg. Three types of toxins exceeded the standard, with exceeding rates of deoxynivalenol (2.54%, 12/473), zearalenone (4.02% ,19/473), and fumonisins (2.54%,12/473), respectively. The samples exceeding the standard were distributed in Mudanjiang, Shuangyashan, Jixi, Harbin, and Qiqihar. Conclusion Corn in Heilongjiang Province is contaminated by a combination of mycotoxins. It is necessary to strengthen monitoring from multiple links and adopt a variety of ways and control measures to reduce corn contamination.
