This research classifies the physical morphology (form and structure) of bioaerosols emitted from open windrow composting. Aggregation state, shape and size of the particles captured are reported alongside the implications for bioaerosol dispersal after release. Bioaerosol sampling took place at a composting facility using personal air filter samplers. Samples were analysed using scanning electron microscopy. Particles were released mainly as small (1μm) single cells, with aggregates occurring in smaller proportions. Most aggregates consisted of clusters of 2–3 particles as opposed to chains, and were |

This research classifies the physical morphology (form and structure) of bioaerosols emitted from open windrow composting. Aggregation state, shape and size of the particles captured are reported alongside the implications for bioaerosol dispersal after release. Bioaerosol sampling took place at a composting facility using personal air filter samplers. Samples were analysed using scanning electron microscopy. Particles were released mainly as small (<1μm) single, spherical cells, followed by larger (>1μm) single cells, with aggregates occurring in smaller proportions. Most aggregates consisted of clusters of 2–3 particles as opposed to chains, and were <10μm in size. No cells were attached to soil debris or wood particles. These small single cells or small aggregates are more likely to disperse further downwind from source, and cell viability may be reduced due to increased exposure to environmental factors.</description><identifier>ISSN: 0956-053X</identifier><identifier>EISSN: 1879-2456</identifier><identifier>DOI: 10.1016/j.wasman.2014.01.021</identifier><identifier>PMID: 24565805</identifier><language>eng</language><publisher>Kidlington: Elsevier Ltd</publisher><subject>AEROSOLS ; Aerosols - analysis ; AGGLOMERATION ; Aggregates ; Aggregation ; AIR FILTERS ; Air Microbiology ; Applied sciences ; Bioaerosols ; CLASSIFICATION ; COMPOSTING ; Dispersion ; EMISSION ; Exact sciences and technology ; INORGANIC, ORGANIC, PHYSICAL AND ANALYTICAL CHEMISTRY ; Microscopy, Electron, Scanning ; MORPHOLOGY ; Other wastes and particular components of wastes ; PARTICLE SIZE ; PARTICLES ; Particulate Matter - analysis ; Pollution ; SAMPLERS ; SAMPLING ; SCANNING ELECTRON MICROSCOPY ; SEM ; Waste Disposal Facilities ; Waste management ; Wastes ; Wood</subject><ispartof>Waste management (Elmsford), 2014-07, Vol.34 (7), p.1101-1108</ispartof><rights>2014 Elsevier Ltd</rights><rights>2015 INIST-CNRS</rights><rights>Copyright © 2014 Elsevier Ltd.
