Ambient air. Biomonitoring with lichens. Assessing epiphytic lichen diversity Ingestion-build-65808 Figure 9 – Pressure apparatus1 Scope This European Standard aims to provide a reliable, repeatable and objective method for assessing epiphytic lichen diversity. According to international literature on the topic (see e. g. [18] for an overall outline), it provides a framework for assessing the impact of anthropogenic intervention, particularly for estimating the effects of atmospheric pollution.
