Odour, dust and non-methane volatile organic-compound emissions from tunnel-ventilated layer-chicken sheds: a case study of two farms

“…Methods for the collection and analysis of odour, dust and NMVOC samples have previously been described by Dunlop et al (2010), Modini et al (2010), Parcsi et al (2011) and Murphy et al (2012). The following is a brief summary of these methods and also describes variations from the previously described methods.…”
