Pollutants of concern to forest ecosystems:
• Aggressive gases (SO2, NOx, O3, fluoride, etc.)
• Acidifying substances (SO2/sulfate, NOx/nitrate, NH4+, etc.)
• Toxic metals (grouped according to volatility)A. HgB. Pb, Zn, Cd, As, Mo, V, - -C. Cu, Ni, Co, Ba, Cr, - -
• Persistent organic pollutantsA. Polyaromatic hydrocarbons (PAH)B. Polychlorinated compounds: PCB, DDT/DDE, HCB, HCH (lindane), - -C. Polybrominated compounds: PBB, PBDE, - -
• Influence on local - regional - continental scale

The Monchegorsk copper-nickel smelter, NW Russia
Among the largest sources of SO2 and heavy metal emissions on a world-wide scale:
• SO2: 98 000 tonnes/year
• Cu: 934 tonnes/year
• Ni: 1619 tonnes/year
• Co: 82 tonnes/year

Effects of air pollutants from copper-nickel smelters on coniferous forest ecosystems:
• Direct effects of sulphur dioxide on the forest canopy
• Toxic effects by heavy metals on soil microflora and sensitive plant species
• Indirect effects of acidic deposition via soil acidification
• Indirect effects of heavy metals by cation exchange displacement of nutrients
