Samples of airborne grain dust representing a variety of grains were examined for the presence of aflatoxins. Although aflatoxins could not be detected in most of the samples, one corn sample contained 130 ppb aflatoxin B1. When the components of this sample were separated according to aerodynamic diameter and analyzed for aflatoxins, it was found that particles with diameters 7-11 micrometers and less than 7 micrometers had much higher levels of aflatoxins than the sample as a whole. These findings suggest that measurements of aflatoxin in whole corn might underestimate aflatoxin levels in corn dust aerosols.
对代表各种谷物的空气中谷物粉尘样本进行了黄曲霉毒素检测。尽管在大多数样本中未检测到黄曲霉毒素，但一个玉米样本中含有130 ppb的黄曲霉毒素B1。当根据空气动力学直径对该样本的成分进行分离并分析黄曲霉毒素时，发现直径为7 - 11微米和小于7微米的颗粒中的黄曲霉毒素含量比整个样本中的含量高得多。这些发现表明，对整个玉米中黄曲霉毒素的测量可能会低估玉米粉尘气溶胶中的黄曲霉毒素水平。
