Odor is a human sensation that is frequently experienced and that nearly all humans understand. Most people realize that an odor is a human perception arising from small quantities of certain chemicals in the air the we breathe. When these chemicals are inhaled, they trigger nerve endings in the nose and mouth that communicate with our brain to interpret them as an odor. However, there is a certain amount of a chemical that must exist in the air we breathe prior to it being identified as an odor. The quantity of a chemical necessary to result in detection of an odor varies across the population (individual sensitivity) and also varies depending on the chemical. The science of odor has been developed around these general concepts. In this talk, I will discuss the basics of odor science, how odors can impact communities, and how we assess the potential for such impacts during project planning or litigation.
