The Olf is a unit used to measure the strength of a pollution source. It was introduced by Danish professor P. Ole Fanger; the name "Olf" is derived from the Latin word olfactus, meaning "sense of scent".
Additional recommended knowledge
One Olf is the sensory pollution strength from a standard person defined as an average adult working in an office or similar non–industrial workplace, sedentary and in thermal comfort, with a hygienic standard equivalent of 0.7 bath baths per day and whose skin has a total area of 1.8 square metres. It was defined to quantify the strength of pollution sources which can be perceived by humans.
The perceived air quality is measured in Decipol.
