Application of Sensory Methods to Evaluate the Effectiveness of Solutions to Reduce the Exposure to Odour Nuisance and Ammonia Emissions from the Compost Heaps

open access: yesSensors
Exposure to high concentrations of odours can result in health effects associated with direct health risks and irritation from nuisance. This investigation aimed to correlate aspects of the waste composting process with the emission levels of malodourous

A Gas Chromatograph-Pedestal Olfactometer (GC-PO) for the Study of Odor Mixtures [PDF]

open access: yes, 2018
Gas chromatography - Olfactometry (GC-O) purifies odorants and delivers them as 1 to 2 second doses to an olfactometer where their odor properties (quale and intensity) can be studied independent of other odors.

Field Air Sampling with SPME for Ranking and Prioritization of Downwind Livestock Odors with MDGC‐MS‐Olfactometry [PDF]

open access: yes, 2009
Air sampling and characterization of odorous livestock gases is one of the most challenging analytical tasks. This is due to low concentrations, physicochemical properties, and problems with sample recoveries for typical odorants.

Identification of biphenyls - contaminants responsible for off-flavour in soft drinks

open access: yesCzech Journal of Food Sciences, 2018
Off-flavour in soft drinks is one of the main threats to manufacturers, which can result in expensive recalls, and discredit the brand. Off-flavours can occur for a variety of reasons (e.g . chemical contamination of raw material).
