This study describes an enhanced method for the measurements of odour impact as per VDI3940 (VDI, 2006), part 1. The methodology incorporates the use of the SM100i in-field olfactometer within the panel of assessors to determine the odour concentration in the assessed site. The results from this enhanced method will allow not only to understand the total odour load determined as per VDI3940 (VDI, 2006), but will also allow us to determine the odour concentration in terms of Odour Units obtained through a reliable in-field olfactometry protocol.
