Soil heavy metal contamination and acid deposition: experimental approach on two forest soils in Hunan, Southern China [PDF]
, 2005 In 1985, a tailing dam collapsed in Hunan province (southern China) leading to soil contamination by heavy metals from the tailings waste. Moreover, acid deposition becomes more and more serious in this area. In this context, two forest soils (a red soil
