title: Identification of aflatoxin B1 in grain elevator dusts in central Illinois.
abstract: Bulk dust samples obtained from grain elevators in the central Illinois area were analyzed for aflatoxin (AFT) content using instrumental two-dimensional high performance thin-layer chromatography (HP-TLC). AFT B1 levels ranged from nondetectable up to 3.5 ppb. This is the first report of AFT occurring in dust in northern grain mills. Long-term exposures of workers to AFT contaminated dust via the respiratory route could pose some hazard.
