1 Definitions

Acid rain is rain

phenomenon caused

by a gas in

water to formacid

rain different In

nature,the rain is

mainly because of

the acidrain has

dissolved CO2

(from the breath of

animals and have a

little Cl-(from

seawater) and pH

below 5.

2 Causes

The cause of acid rain phenomenon is the growing power of sulfur and nitrogen oxides in the atmosphere by human activities cause The power plants using fossil fuels for power generation has also released into the atmosphere large amounts of NOx, SO2 and by the transport active

SO2 can also be emitted from

volcanic activity When active

volcanoes usually emit H2S and

SO2 atmosphere

3 The generation of acid rain

4 Impacts

Acid rain affected directly or indirectly to the lakes and the aquatic environment through the pH

pH The expression

pH < 6,0 The lower organisms of the food chain died (as

fleeting ) this is an important source of fish food

pH < 5,5 Fish can not breed The fry are very hard to

survive Big fish are deformities due to malnutrition

pH < 5,0 Fish populations die

pH < 4,0 Emergence of new organisms other organisms

initially

The leaves fall off and the process of photosynthesis is affected seriously

The effects of acid rain on plants and soil

Affect the atmosphere

The acid fog affects the ability to spread sunlight

Affect the structures and materials

The acid rain falling buildings and the statue will corrode them damage the fabric, books and valuable antiques

Effects on people

system and cause neurological disease in humans

 The direct effects of pollution due to the acid gases including respiratory diseases such as asthma, whooping cough and

headaches, sore eyes, sore throat

5 Solutions

 By all means reduce the energy consumption of petroleum and

coal, trying to apply nuclear energy, solar energy, wind water energy and wind to reduce the amount of NO2, SO2, CO2 emissions into the air
