Sampling for airborne microorganisms downwind of waste management and intensive farming facilities is an area that requires further research – these types of facilities are known to emit bioaerosols of health significance but currently there is a lack of information on the most appropriate sampling techniques, target microorganisms, analytical approaches and the best way in which to achieve an accurate representation of emissions from facilities which recognises their spatial and temporal nature.

This project focuses on detection and characterisation of inflammatory agents in bioaerosol emitted from biowaste and intensive agriculture. It is known that cellular components (e.g. endotoxin and glucan) are emitted by composting and farming. Endotoxin binds to receptors associated with many cell types generating pro-inflammatory cytokines, resulting in inflammatory response in exposed people. Endotoxin has advantages as a bioaerosol metric – it is: • detectable through robust methods • a broad-spectrum indicator of bacterially-derived (Gram negative) bioaerosol • the only bioaerosol component for which an exposure limit to protect the general population is currently realistic. Whilst promising, only a small database exists of endotoxin concentrations around composting / farming facilities and little is known about exposure of the general population (as opposed to occupational exposure). Little knowledge exists on the size fractions that airborne endotoxin is associated with, the relative importance of whole cells (live/dead), vesicles and disrupted fragments, or its dispersion properties. Although robust detection methods exist, there are presently no rapid or continuous detection methods available.
