Data on the elemental composition of lichens in the landscapes of the Central Siberian taiga
The elemental composition of lichens was identified to assess ground-level air in the landscapes of the Siberian taiga which form the ecological framework of Northern Eurasia. The samples were collected in multiple locations in the southeastern part of the Central Siberian State Biosphere Reserve (C...

The elemental composition of lichens was identified to assess ground-level air in the landscapes of the Siberian taiga which form the ecological framework of Northern Eurasia. The samples were collected in multiple locations in the southeastern part of the Central Siberian State Biosphere Reserve (CSSBR), mainly along the river valleys. This territory represents the background conditions due to its protected status. The territory is confined to the lower part of the catchment area of the Podkamennaya Tunguska River in the Evenki Municipal District of the Krasnoyarsk Territory. The samples were collected from thin branches of coniferous trees at a height of 1.5–2 m above the day-surface level from at least 10 adjacent trees within the individual areas of 10 to 20 m2 and then mixed to form composite samples for each area.
