What is BS EN 16789– Ambient air about?
BS EN 16789 applies to the determination of the impact of ground-level ozone on a bioindicator plant species.
BS EN 16789 specifies the procedure for setting-up and use of a system designed to expose these plants to ambient air. It also describes the procedure for leaf injury assessment.
BS EN 16789 applies to the outside atmosphere in all environments. BS EN 16789 does not apply to the assessment of air quality inside buildings.
The method described in BS EN 16789 does not replace modelling or physicochemical methods of direct measurement of air pollutants.
Who is BS EN 16789– Ambient air for?
BS EN 16789 on ambient air is relevant to:
- Microbiologists
- Manufacturers and industries processing tobacco
- Researchers and scientists
- Environmentalists
Why should you use BS EN 16789– Ambient air?
When tobacco fields and greenhouses are exposed to ozone, it can cause serious injury.
In BS EN 16789, the procedure for setting up and operating a system designed to expose these plants to ambient air is described, as well as the procedure for assessing leaf injury. As a result of the standardized tobacco exposure, ozone-caused injury to bioindicators is revealed, and thus a spatial and temporal distribution of the effects of ozone on plants can be determined, as described in BS EN 16789. In BS EN 16789, performance criteria and test procedures for biomonitoring of plants. This helps create an improved solution to deal with harmful gasses emitted by stationary sources, which are very toxic and deplete the ozone layer.
BS EN 16789 is a best practice guidance standard that provides complete requirements and sampling procedures for standardized tobacco exposure and controlling their quality.
