Protocols For Reliable Field Olfactometry Odor Evaluations

Specific gasses (odorants) are often poorly correlated with odors, which require human perception. Thus, olfactometry is used to quantify odors, which commonly contain a complex mixture of offensive compounds. Laboratory‐based dynamic olfactometry is expensive and time‐consuming, and it is accompanied with sample container/ preservation issues. Field olfactometry provides real‐time measurements at lower detection levels, but is influenced by environmental factors. This study explores the use of field olfactometry for quantifying dilutions‐to‐threshold (D/T) of environmental malodors. Nasal Ranger Field Olfactometer (NRO) instruments were used to collect 3096 individual D/T observations at livestock facilities in central Pennsylvania…,Get the article to read more
