olf
n.— «The idea is to express any pollution source by a comparable known reference source. The new unit is called one “olf,” from the latin word olfactus (olfaction), although both the olfactory and the chemical sense are involved in the definition of the unit. One olf is the emission rate of air pollutants (bioeffluents) from a standard person.» —“Introduction of the olf and the decipol units to quantify air pollution perceived by humans indoors and outdoors” by P.O. Fanger Energy and Buildings Aug. 17, 1987. (source: Double-Tongued Dictionary)
