Odour Sampling System - Odour Sample Collection to Quantify Odour Emission Rates |
 | | Odour measurement requires representative samples of the air to be drawn into a sample bag and rapidly transported to an odour laboratory for olfactometric testing. |
| | Odours emit from various sources, such as stacks in an industrial process, aeration tanks in wastewater treatment plant, composting piles in a mushroom composting plant, chicken sheds on a poultry farm and cattle feedlots. |
| | The quantity of odour emitted is not determined directly by olfactometry but is calculated from the concentration of odour (as measured by olfactometry) which is then multiplied by the volume of air passing through the hood per unit time. |
