In 1992, a monitoring survey on a national scale was carried out using Hypogymnia physodes as a biomonitor for trace element air pollution. The primary aim was to analyse epiphytic lichens to gain information about the levels of elements in the atmosphere and to identify significant pollution sources. The geographical concentration patterns of the trace elements obtained from the lichen data were mapped and compared with the Index of Atmospheric Purity (IAP) calculated on the basis of data from lichen thalli type mapping, obtained on a more dense bioindication grid in 1991.
