| Abstract: | Although the soils in the Huludao area can accommodate a certain amount of acid rain, continuing discharge of SO 2 from the zinc plant has caused noticeable deterioration of the agro-ecological system in the area, especially in the recent years. Soil survey indicated that the effective sulfur content of the surface soil(0-20cm)has increased by 100 to 500%, while the total sulfur content by 21.38% to 87.86%. In some severely affected areas, the pH value has lowered to 5.05 - 5.53. Acid rain, as a result of the SO 2 discharge, is causing more and more damage to the agro-ecological system. Measures must be taken to control the SO 2 discharge from the zinc plant. |
