Background of development of Triangle Odor Bag Method

Giving an Odor to Carbon Monoxide: Malodorogenic Sensing of Carbon Monoxide via [IrCl(cod)(NHC)] Complexes

“…The formed olefin is characterized by a distinct smell, which can be detected by the human olfactory system with very high sensitivity. The odor threshold for 1,5‐cyclooctadiene determined by the triangle bag method is 0.00087 ppm, which is in the same range as that of H 2 S . The malodorogenic reaction can be viewed as a chemical translation in which odorless, but highly toxic CO is translated into strongly smelling, low‐toxicity 1,5‐cyclooctadiene.…”

Screening of deodorizing active compounds from natural materials and deodorizing properties of cineole

“…The review by Iwasaki indicated that the human olfactory sense is generally capable of clearly discriminating differences in odor intensity when there is a 10fold difference between two odor concentrations and can recognize as little as a 3-fold difference in odor concentration 14) . As such, it is preferable for newly developed deodorant products to exhibit deodorizing activity of approximately 90% against odorous gases.…”

Perception of Odour Pollution Impact from Waste Treatment Plant on Health, Psychology and Physiology of Sensitive Receivers

“…The scope of odour studies is not limited to impact on general well-being as noted by Nicell and Tsakaloyannis (2003), NRCCO (1979) and Shusterman (1992). Studies also covered perception issues (Sakawi et al, 2011;Whitherspoon and Barnes, 2009) origin and source of odour (Applied Environmental Research Centre, 2001;Sironi et al, 2005;Stern, 2007), sampling and analysis of odour (Zarra et al, 2009;Sironi et al, 2007;Sakawi et al, 2011;Davoli et al, 2003;Romain and Nicolas, 2009;Drew et al, 2007); and odour control (Morcet et al, 2003;Chen et al, 2003;Otieno and Magagula, 2001;Fukuyama, 2004;Iwasaki, 2004;Bedogni and Resola, 2002;Hurst, 2005).…”
