在葫芦岛地区 ,由于锌厂常年 (尤其是近期 )排放SO2 已使该区土壤性质受到了严重的影响 .测定结果 :土壤表层 ( 0～ 2 0cm)有效S提高 1～ 5倍 ,全S含量提高 2 1 .38%～ 87.86% ,在严重影响区 pH值已下降至 5 .0 5～ 5 .0 3.锌厂排放的SO2 所形成的酸雨危害不可忽视
In Huludao area, the soil properties were seriously affected by the SO2 emission from the zinc plant all year round (especially in the near future), and the results showed that available S was increased by 1 to 5 times in the surface layer (0 ~ 20 cm) Increased by 21.38% -87.86%, and the pH value in the seriously affected area had dropped to 5.05-5.0. 3. The acid rain caused by SO2 emitted by the zinc plant can not be ignored
