Elevated Cu concentration in forest mosses wasdetected as far as 30–40 km from the smelter in 1995 (Kubin et al.2000) (Fig.2).With the moss bag method high airborne pollution of copper,nickel,zinc,lead,cadmium (Hynninen 1986)and mercury (Hynninen and Lodenius 1986)were observed in 1982 up to a distance of 9 km.Up to 4 km during 1992–1996 bulk deposition in open areas and stand throughfall,i.e.deposition inside the stand,was contaminated with sulphate and heavy metals (Derome and Nieminen 1998).The deposition of Cu was high close to the smelter the bulk deposition being 160 mg m-2 y-1 ,and stand throughfall 360 mg m -2y-1 (Derome and Nieminen 1998).At 8 km both the bulk deposition and stand throughfall were ca.3 mg m -2y-1 .The respective values for Ni close to the smelter were 70 and 140 mg m -2y-1 and for Zn 20 and 40 mg m-2 y-1 ,whilst at 8 km the values were ca.one tenth of these.
