Particle size distribution of airborne Aspergillus fumigatus spores emitted from compost using membrane filtration.
5698 - 5701.
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 50 m downwind of a green waste compost screening operation at a commercial facility. The highest concentrations (approximately 8 x 10(4) CFU m(-3)) of culturable spores were found on filters with pore diameters in the range 1-2 mu m 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 < 0.01) indicating that the two methods are directly comparable across all particles sizes for Aspergillus spores. (C) 2009 Elsevier Ltd. All rights reserved.
