Sulphur behaviour in forest soils near the largest SO2 emitter in northern Europe
The impact of 60 a of SO2 emissions from a Ni-Cu plant in the Kola Peninsula (Russia) on soil S contents was assessed in podzols under pine forests. Sulphate desorption and the possible delay of acidification reversal was investigated, because the plant will be reconstructed in 2006 with an expected...
