      <subfield code="a">The sampling convention for inhalable dust, proposed by the Comité Européen de Normalisation and the American Conference of Governmental Industrial Hygienists, is undefined for particle sizes larger than 100 mc owing to experimental difficulties in its measurements. This paper estimates lower and upper envelopes for the inhability of these larger particles, for the low air velocities predominating in indoor work places. Estimates of the inhalable aerosol mass of particles exceeding 100 mc are then obtained for the workplace particle size distributions published in the mass median aerodynamic diameter is smaller than 25 mc the inhalable mass above 100 mc is negligible</subfield>
