Comparison of odour emission rates measured from various sources using two sampling devicesN Hudson
International Laboratory for Air Quality and Health, School of Physical and Chemical Sciences, Queensland University of Technology, Brisbane, Queensland, Australia
Bioresour Technol 100:118-24. 2009..These results have great significance for users of odour dispersion models, for which an odour emission rate is a key input parameter...

International Laboratory for Air Quality and Health, School of Physical and Chemical Sciences, Queensland University of Technology, GPO 2434, Brisbane, Queensland 4001, Australia
Bioresour Technol 99:6409-18. 2008..A plausible hypothesis, consistent with likely mechanisms for the odour reduction and the olfactometric method used to quantifying the efficacy of the covers, is offered...
Odour sampling 1: Physical chemistry considerationsN Hudson
International Laboratory for Air Quality and Health, School of Physical and Chemical Sciences, Queensland University of Technology, GPO 2434, Brisbane Queensland 4001, Australia
Bioresour Technol 99:3982-92. 2008..Such consideration may identify the most appropriate situations under which the use of these devices may or may not be correct...

Evaluation of a novel wind tunnel for the measurement of the kinetics of odour emissions from piggery effluentJ H Sohn
Intensive Livestock Systems Unit, Queensland Department of Primary Industries and Fisheries, PO Box 102, 203 Tor Street, Toowoomba, Queensland, Australia
Water Sci Technol 50:49-55. 2004..0 L/min respectively. This study suggested that the wind tunnel would provide precise estimates of odour emission rate. However, the wind tunnel needs to be calibrated to compensate for errors caused by different air flow-rates...
Laboratory investigation of supported permeable organic covers for the management of odour emissions from anaerobic piggery waste pondsN Hudson
Intensive Livestock Environmental Management Services, Queensland Department of Primary Industries, PO Box 102, Toowoomba, Queensland 4350, Australia
Water Sci Technol 44:317-26. 2001..While greenhouse gas emissions appear to vary according to cover type, the overall significance of these emissions is not yet clear. The impact of permeable pond covers on overall pond performance requires additional research...
Odour emissions from anaerobic piggery ponds. 1. Results of a three season, 14-month surveyN Hudson
