Aflatoxin in respirable corn dust particles

Abstract
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 samples, 1 corn sample contained 130 ppb aflatoxin B1. When the components of this sample were separated according to aerodynamic diameter and analyzed for aflatoxins, particles with diameters 7-11 .mu.m and < 7 .mu.m had higher levels of aflatoxins than the sample as a whole. Measurements of aflatoxin in whole corn might underestimate aflatoxin levels in corn dust aerosols.
