Acid Deposition and its Effects were Studied by Analysing the Chemistry in Precipitation, Stream Water, Soil Water and Soils in Two Catchments in Hunan.one Site, Linkesuo (Denoted LKS), is on the Outskirts of Changsha, the Provincial Capital of Hunan, the other (Bailutang, Denoted BLT) on the Outskirts of Chenzhou in Southern Hunan.Volume-weighted Average pH Values and Sulphate Concentrations in Wet Deposition were 4.58 (Blt) and 4.90 (Lks) and 174 μmolc L-1 and 152 μmolc L-1, Respectively.Wet Deposition of Sulphate has been Estimated as 4.3 ...
