食品样品中霉菌毒素的存在及其对人体健康的影响已被广泛研究，然而，有关其在环境中的分布的信息是稀缺的，分析方法包括固相萃取程序，然后进行液相色谱串联质谱分析和验证的饮用瓶装沃茨中霉菌毒素的痕量分析。该方法达到的定量限为0.2 ng L-1之间的黄曲霉毒素和赭曲霉毒素，伏马菌素和新茄醇2.0 ng L-1。该方法应用于真实的样品。黄曲霉毒素B2是最常在水样中检测到的霉菌毒素，最高浓度为0.48 +/- 0.05 ng L-1，其次是黄曲霉毒素B1、黄曲霉毒素G1和赭曲霉毒素A。真菌中枝孢属、镰刀菌属和青霉属的检出率较高。这些结果表明，饮用这些沃茨对成人没有毒理学风险。(C)2015爱思唯尔有限公司版权所有。
The presence of mycotoxins in food samples has been widely studied as well as its impact in human health, however, information about its distribution in the environment is scarce.An analytical method comprising a solid phase extraction procedure followed by liquid chromatography tandem mass spectrometry analysis was implemented and validated for the trace analysis of mycotoxins in drinking bottled waters. Limits of quantification achieved for the method were between 0.2 ng L-1 for aflatoxins and ochratoxin, and 2.0 ng L-1 for fumonisins and neosolaniol. The method was applied to real samples. Aflatoxin B2 was the most frequently detected mycotoxin in water samples, with a maximum concentration of 0.48 +/- 0.05 ng L-1 followed by aflatoxin B1, aflatoxin G1 and ochratoxin A. The genera Cladosporium, Fusarium and Penicillium were the fungi more frequently detected. These results show that the consumption of these waters does not represent a toxicological risk for an adult. (C) 2015 Elsevier Ltd. All rights reserved.
