3. Definition of Acid Rain
Normal pH value of Rain is 5.6
pH value < 5.6 Acid Rain
All forms of precipitation, snow,
rain, hail or dust particles, that
contain a degree of acidity higher
than those which normally occur in
nature.

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.

10. 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.
15. Buildings
Construction materials such as
limestone, marble and sandstone can
also be damaged by acid rain, resulting
in eroded buildings and monuments.
Value loss
17. Human Health
Acid rain can aggravate respiratory
ailments such as bronchitis and asthma.
Drinking water which contains higher
levels of toxic metals
