3. Acid Rain
Acid rain, or acid deposition, is
a broad term that includes any
form of precipitation with
acidic components, such as
sulfuric or nitric acid that fall to
the ground from the
atmosphere in wet or dry
forms.
This can include rain, snow, fog,
hail or even dust that is acidic.

4. Caussess :
The major sources of SO2 and NOX in the
atmosphere are:
1. Burning of fossil fuels to generate
electricity.
2. Vehicles and heavy equipment.
3. Manufacturing, oil refineries and
other industries.

7. Effects :

8. Effect on Forests:
Forest damage due to acid rain is most evident
in Eastern Europe – especially Germany,
Poland and Switzerland.

9. Effect on Soil:
• highly impacts on soil chemistry and biology
• soil microbes and biological activity as well as soil
chemical compositions such as soil pH are damaged

10. Effect on Architecture
and Buildings:
• Acid rain on buildings, especially those constructed with
limestone, react with the minerals and corrode them away.
• Modern buildings, cars, airplanes, steel bridges and pipes
are all affected by acid rain.

11. Effect on Public Health:
Intensified levels of acid depositions in dry form in
the air can cause lung and heart problems such as
bronchitis and asthma.

12. Greenhouses
A greenhouse (also called
a glasshouse, or, if with
sufficient heating, a hothouse)
is a structure with walls and
roof made chiefly of
transparent material, such as
glass, in which plants requiring
regulated climatic conditions
are grown.
