      <subfield code="a">This paper extends the idea, presented in an earlier communication, that dust sampling for studinng health effects should take account of aerodynamic processes both inside and outside the body. A rationale is described for the inhalable dust spectrometers wich have been suggested as samplers to be used in new epidemiological enquiries. By means of these versatile instruments, it is possible in principle to obtain the aerodynamic size distribution and airborne mass concentration of particles contained within the inhalable fraction and then within any number of chosen deposition sub-fraction. By way of illustration, some typical results obtained using a new inhalable dust spectrometer in a coal mine are used to examine the effects of changing breathing pattern on the dust dose received by the respiratory regions of the lungs of exposed workers</subfield>
