Dust and odour emissions from layer sheds

Odour, dust and non-methane volatile organic compound (NMVOC) emissions were measured at tunnel ventilated layer (egg production) sheds over several seasons in Queensland and Victoria. Emission rates were found to vary between farms presumably due to management and environmental factors. Emissions data that has been collected will improve scientific understanding and support improved planning of new layer farms. NMVOCs are the building blocks of odour—mixtures of specific odorous NMVOCs combine to form what people recognise as poultry odour—and influence its character and strength. NMVOC composition of layer shed odour samples was analysed to provide knowledge that will be vital for the strategic development of odour mitigation strategies and real time monitoring
