  abstract = {{T}he oxidative dissolution of mine wastes gives rise to acidic, metal-enriched mine drainage ({AMD}) and has typically posed an additional risk to the environment. {T}he poly-metallic mine {D}abaoshan in {S}outh {C}hina is an excellent test site to understand the processes affecting the surrounding polluted agricultural fields. {O}ur objectives were firstly to investigate metal ion activity in soil solution, distribution in solid constituents, and spatial distribution in samples, secondly to determine dominant environment factors controlling metal activity in the long-term {AMD}-polluted subtropical soils. {S}oil {C}olumn {D}onnan {M}embrane {T}echnology ({SC}-{DMT}) combined with sequential extraction shows that unusually large proportion of the metal ions are present as free ion in the soil solutions. {T}he narrow range of low p{H} values prevents any p{H} effects during the binding onto oxides or organic matter. {T}he differences in speciation of the soil solutions may explain the different soil degradation observed between paddy and non-paddy soils.},
