What is BS EN 16414– Ambient air about? 
BS EN 16414 describes the sampling protocol and the preparation of samples of in situ mosses to monitor the bioaccumulation of atmospheric contaminants.
BS EN 16414 specifies the actions that shall be taken from the field sampling of mosses to their final preparation before analysis for targeted contaminants.
BS EN 16414 is of interest to all operators wishing to conduct air quality biomonitoring studies.
Who is BS EN 16414– Ambient air for? 
BS EN 16414 on ambient air is relevant to: 
- Microbiologists 
- Manufacturers and industries processing tobacco 
- Researchers and scientists 
- Environmentalists 
Why should you use BS EN 16414– Ambient air? 
It is important to emphasize that biomonitoring data are completely different from those obtained through Physico-chemical measurements and computer modelling.
BS EN 16414 specifies the actions that shall be taken following the field sampling of mosses to their final preparation to monitor the bioaccumulation of pollutants in the atmosphere.
BS EN 16414 sets out the sampling protocol and the preparation of samples of in situ mosses.
In BS EN 16414, performance criteria and test procedures for biomonitoring with mosses. 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 16414 is a best practice guidance standard that provides complete requirements and sampling procedures for standardized tobacco exposure and controlling their quality.
