Ambient air. Biomonitoring with Higher Plants. Method of the standardized tobacco exposure has-digital Operational and performance requirements include1 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. The present document 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.
