Ambient air. Biomonitoring with Higher Plants. Method of the standardized tobacco exposure has-digital for which the necessary inspection1 Scope This European Standard applies to the determination of the impact of ground level ozone on a bioindicator plant species (tobacco Nicotiana tabacum cultivars Bel W3, Bel B and Bel C) in a given environment.
