  4. Damage of Acid Rain • Soil • Forests / vegetation • Aquatic organisms • Ancient Buildings • Buildings • Human health

  5. Soil • Soils can be damaged by removing needed nutrients and dissolving toxic heavy metals from the soil. • Not Suitable for farming

  6. Forests / Vegetation • Acid rain can damage the foliage of trees (leaves etc.), and retard their growth. • Metals such as aluminum can get into the roots of plants and prevent the uptake of other important nutrients.

  7. Aquatic organisms • Increasing the concentration of toxic heavy metals in surface waters. • Acidification can hinder the ability of aquatic organisms to reproduce. • Ecosystem will be collapse.

  8. Healthy Acidize

  9. Ancient Buildings • Damage of Ancient Buildings

  10. Buildings • Construction materials such as limestone, marble and sandstone can also be damaged by acid rain, resulting in eroded buildings and monuments. • Value loss
