Fourteen different moss samples were used as bioindicators to study the atmospheric deposition of metals around polluted and unpolluted areas in Trabzon, Turkey. Samples were analyzed using flame and graphite furnace atomic absorption spectrometry (AAS) after microwave digestion. Good accuracy was assured by the analysis of standard reference material. A total of six trace metals (Fe, Cu, Mn, Zn, Pb, Cd) were determined. Metal concentrations were in the mu g/g range 1150.0-6137 (Fe), 13.6-33.6 (Cu), 329.2-806.0 (Mn), 84.4-144.4 (Zn), 9.230.4 (Pb), and 0.7-1.7 (Cd).
