      <subfield code="a">The dimensions of airborne fibre collected at an underground mine and two mills producing crocidolite in the Kuruman area of Cape Province, South Africa, and of those collected at a plant maufacturing pipes in South Africa using Cape crocidolite and chrysotile asbestos are reported. The measurements were made using a transmission electron microscope, a scanning electron microscope and a ligh optical microscope. The proportion of long fibres in the air has been found to be very small and observations on very large numbers of fibres are necessary to confirm their presence</subfield>
