  Abstract:  Soil samples were collected from 7 sampling stations (in duplicate) and associated terricolous lichen (Cladonia fimbriata and Cladonia coniocraea) and moss (Bryum argenteum) samples along an W-E transect from Zlatna plant. Cladonia and moss samples were digested with HNO3 + H2O2 mixtures and analyzed for Pb, Zn, Cu using acetylene-air flame atomic absorption spectrometry. Chemical analyses of bulk samples for soil-surface horizons were digested with Lunge mixture and analyzed also with FAAS. Lead and Cu contents decreased more-or-less linearly with increasing distance from the ore-processing plant and soil pH values increased as a function of distance. Soils (surface horizons) are acidic virtually throughout the area. Lichen and moss metal content was significantly higher than soil metal content. Metal concentrations are amongst the highest reported for natural ecosystems, the most serious being for Pb.
