<abstract displayLabel="Summary">Simultaneous airborne dust samples were taken with five types of instrument, namely, konimeter, thermal precipitator, membrane filter, tyndallometer and VC 25 gravimetric sampler, on the surface and underground at two types of asbestos mine, producing amosite and Cape crocidolite respectively. The results were analysed and compared in terms of five different concentration parameters, namely, particles plus short fibres, long fibres, particles plus short fibres plus long fibres, the volume and the mass of dust</abstract>
