Abstract

Two different methods were applied for estimating the yearly emission rate of a fly-ash storage site. In applying the first method, the dust emissions from the individual sources were assessed and then added up, resulting in an estimate of the yearly dust emission. In applying the second method, a series of long-term meteorological data, and measurements of fugitive-dust concen- trations and size distributions at various receptor points were entered into a fugitive-dust dispersion model. Fugitive dust was sampled using Coarse Dust Recorders. The samples were analysed by means of automatic image analysis. The measurement- and analytical methods applied were found to be usable for assessing the yearly dust emission of a fly-ash storage site. The yearly dust emission of the storage site under investigation was estimated at between
