Direct Olfactometry

Measurement of odour without a time lag between sampling and analysis

The relative location of an observer with respect to a source of odour emission.

Mixing of odorous gas and odour-neutral air measured by flow rate

Dynamic Dilution Olfactometry is based on “dilution to threshold” of a gas sample with multiple components.

A device that mixes neutral gas (odourless air) with odorous gas in a specified ratio by flowrate and delivers mixture to an outlet for analysis

An electronic nose (e-nose) uses a sensor array that reacts to air pollutants by leaving behind a ‘fingerprint’ that can be attributed to an odour

Exposure is a combination of the amount of a pollutant in the air and the amount of time that a person stays in the presence of a pollutant.

FIDOL represents frequency, intensity, duration, offensiveness and location.

The assessor is presented with two or more ports, of which one presents the stimulus and the other(s) neutral gas

Unintentional emissions from, for example; flanges, valves, doors, windows; that is points which are not designated or intended as a release point
