"The concentrations of N, Fe, Zn, Pb, and Cu in Cladonia decreased towards the inland and northern sites, probably reflecting similar regional differences in the atmospheric fallout." The data also suggest that "... there is significant active uptake of the macronutrients P, N, and K, while Ca is primarily bound passively at the cation exchange sites and is only weakly retained by Cladonia." The author also found that "... iron and lead are concentrated in the dead basal parts, but postassium, nitrogen and phosphorus are chiefly accumulated in the living top part."]
