Is it possible to draw an analogy between the perception of odors and noise? Both the public and professionals are familiar with the noise measurement expressed in decibels. Noise is also formed of frequencies (treble or bass). Series of sounds can create melodies that would trigger emotions.
There are several odor measurement methods. Characterization via chemical analysis and sensory or olfactometric characterization have advantages and drawbacks. Despite the known benefits of the conventional chemical analysis characterization (accuracy, reproducibility, etc.), olfactometric measures are generally preferred due to the characteristics of the measured parameters
Odotech launched OdoView which is a tool that simplifies the collection and management of odor complaints in real time. It also converts odor complaint reporting into factual and quantifiable data and information. OdoView is a real time odor complaint management platform.
In many ways, odor modelling is not very different from dispersion modelling for criteria pollutants. The same basic models in use and referenced by U.S. EPA Guidelines and clearinghouse memorandum. However, there are some basic differences in odor modelling from criteria pollutant modelling that are not clearly understood and quite often distorted.
Odor nuisance standards do not preclude the occurrence of odors that are above the odor threshold limit. The nuisance standard only precludes that the frequency cannot be such that a person cannot enjoy the use of his property or conduct business. When conducting an odor impact assessment, one needs to define whether this translates to a 0.1, 1 or 10 percent exceedence criteria.
