Abstract
Simultaneous samples of different aerosols generated in the laboratory or occurring in the field were obtained by using respirable-size selective gravimetric and midget impinger samplers. Dust concentrations, expressed as respirable weight per unit volume and as number of particles per unit volume, were compared, looking toward a way of converting respirable mass values to equivalent number concentrations. An empirical relationship of 5.6 million particles per cubic foot equivalent to 1 milligram of respirable dust per cubic meter was derived from 23 sets of samples.This publication has 2 references indexed in Scilit:
