      <subfield code="a">Palygorskite, a fibrous clay mineral, is being used as a substitute for asbestos in some applications. Nine specimens obtained from different geological locales were studied for mineral purity, elemental composition, fibre size distribution, and surface binding characteristics. This study shows the importance of selecting several mineral specimens for health hazard evaluation</subfield>
