      <subfield code="a">A preliminary study of a liquid sedimentation technique is described that was used to determine respirable particle fractions for a variety of insoluble dusts. Side-by-side comparisons of sedimentation and averaged cyclone respirable fraction measurements gave fairly good agreement. This method provides a rapid, inexpensive, and easy way to obtain estimates of the respirable fraction of bulk dust samples</subfield>
