Rhine River pollution event
 on November 1,1986
 Basel, Switzerland

storehouse
 More than 60 million fish were poisoned, 500 kilometers on both sides
of the well water became undrinkable, near the river’s water plant shut
down. The Rhine will therefore “dead” for 20 year
Cause
Nowadays, water pollution is deteriorating. Rivers, lakes and even oceans all over the
world are becoming polluted by garbage and dangerous chemicals. Oil and other
Chemicals can kill fish and make water unsafe for drinking
1.Natural pollution
Due to the dissolution of geological, atmospheric precipitation leaching, erosion on
the ground, mix the various pollutants into the water
2. Man-made pollution
1. industrial wastewater (工业废水)
2. Daily life sewage (生活污水)
3. Pesticide and fertilizer pollution （农业化肥污染）
Influence
1.For business or industry, it affects products’ quality ,
increased corrosion of products, and so on.
2.For individual, it does damage to the human’s healthy.
There are many influence that we can’t describe them by words. So we will
show you some pictures.
The effects of water pollution are varied. They include poisonous drinking water,
poisonous food animals .
The polluted water not only kills fish, it is also harmful to our health. Many people
get sick because they drink the polluted water. In some rivers the water is so dirty that
they can even kill plants.
How to decrease those problems
1.The country should try to do somethings to change this situation .The goveronment
have done a lot of work to stop pollution.

2.In nowadays, science provides many practical solutions to minimizing the present
level at which pollutants are introduced into the environment and for remediating
(cleaning up) past problems.

3.Promote people's awareness of preserving water resource.
For government
1.The establishment of urban sewage treatment system(城市污水处理系统的建立 )

2 Industrial restructuring （产业结构调整）
3.The development of new water sources
4.To strengthen the planning and management of water resources
5.Controlling agricultural non-point source pollution.（控制农业面源污染）
For Business
1. To reduce water consumption(减少耗水量)
2. Buy equipment of sewage treatment (买污水处理设备)
3. Don‘t discharge sewage into water.(不要乱排污水)
4. Water recycling system

For individual
.Don’t use cleaner conclude P.

2. Don’t throw the garbage into the river or sea.
3.Tell the person around you to protect the water
Now more and more people have realized how serious the problem is. Our
government is doing its best to take measures to fight against pollution. We've done a
good deal of work, but there's still a long way to go. We must keep on fighting until
we find ways to protect the environment from being polluted, and do away with
pollution. We are sure that we'll win the battle.
