A habitat of the polluted fungi is bog ecosystems. The places where the contaminated fruit bodies were collected do not belong to official Chernobyl trace territories specified on the map of caesium-137 pollution in the Leningrad Region. It suggests including the <em>Leccinum holopus</em> in reference group of organisms for the purposes of ecological monitoring caesium-137 in wood communities and bog ecosystems.</p> ER -
