Mosses, epiphytic lichens and tree bark as biomonitors for air pollutants – specifically for heavy metals in regional surveys
Abstract The thesis consists of regional forest condition studies, using different biomonitors. Heavy metal deposition was investigated in 1985–2000 on the basis of the heavy metal concentrations (As, Cd, Cr, Cu, Fe, Hg, Ni, Pb, V, Zn) in mosses in Finland. A comparison on the suitability of mosses,...
