Abstract

Information on the particle size distribution of bioaerosols emitted from open air composting operations is valuable in evaluating potential health impacts and is a requirement for improved dispersion simulation modelling. The membrane filter method was used to study the particle size distribution of Aspergillus fumigatus spores in air 50m downwind of a green waste compost screening operation at a commercial facility. The highest concentrations (approximately 8×104CFUm-3) of culturable spores were found on filters with pore diameters in the range 1-2μm which suggests that the majority of spores are emitted as single cells. The findings were compared to published data collected using an Andersen sampler. Results were significantly correlated (p
