Airborne aflatoxin generated in rice and maize processing plants was assayed by an indirect competitive enzyme-linked immunosorbent assay. In the rice mill, levels of airborne aflatoxin were always higher in the respirable dust samples (< 7 microns) compared with the total dust samples (< 7 microns). The concentrations of total airborne aflatoxin in the respirable dusts were 26 picogram/m3 and 19 pg/m3, respectively, for the workplace and the storage area of the rice mill, while the concentrations of total dust were 12 pg/m3 for the workplace and 11 pg/m3 for the storage area. Airborne aflatoxin was not detected in control sites of either of the grain processing plants or from the total dust samples obtained from the maize plant. Three sites in the maize processing plant-the elevator (18 pg/m3), the loading/unloading area (800 pg/m3), and the oil mill (816 pg/m3)-showed the presence of airborne aflatoxin only in the respirable dust samples.
采用间接竞争酶联免疫吸附测定法对大米和玉米加工厂产生的空气中黄曲霉毒素进行了检测。在碾米厂，可吸入粉尘样本（<7微米）中的空气中黄曲霉毒素水平始终高于总粉尘样本（<7微米）。碾米厂工作场所和储存区域可吸入粉尘中空气中黄曲霉毒素的总浓度分别为26皮克/立方米和19皮克/立方米，而工作场所总粉尘浓度为12皮克/立方米，储存区域为11皮克/立方米。在这两个谷物加工厂的对照点或从玉米厂获得的总粉尘样本中均未检测到空气中黄曲霉毒素。玉米加工厂的三个地点——升降机（18皮克/立方米）、装卸区（800皮克/立方米）和榨油厂（816皮克/立方米）——仅在可吸入粉尘样本中检测到空气中黄曲霉毒素的存在。
