GermanyGermany
• Water Pollution:– Industrial wastes and oil from ships emitted
into lakes, rivers and streams– Wastes run into North Sea– Outdated sewage treatment facilities also
pollute– Baltic Sea is polluted by raw sewage

GermanyGermany
• Air Pollution:– 43 million cars and coal burning industries
contribute air pollution (leads to acid rain)– Acid rain has damaged ¼ of the Black Forest

GermanyGermany
• Solution:– Government is working to meet standards set
up by the European Union to clean and dispose of waste properly
– Also setting up nature preservation lines

United KingdomUnited Kingdom
• Not much pollution, but they are working to reduce greenhouse gas emissions– Passing laws for better cars and factories
• Big on recycling– 25% of household wastes are recycled; goal
is to increase to 35% by 2015

• Chernobyl Nuclear Power Plant
• In 1986, the USSR generated 10% of the world’s nuclear power.
• Chernobyl exploded on April 26, 1986
• 200,000 people evacuated to decrease exposure to radiation

What went wrong?What went wrong?
April 25th, 1:00 amThe reactor was scheduled to shut down for maintenance. While preparing for
the shutdown, the operators wanted to perform a test to see how long the turbines could run the emergency cooling system if power is interrupted by
an accident.

April 25April 25thth, 1:05 pm, 1:05 pm
With the reactor "slowing" down in preparation for the shutdown, the power in Reactor No. 4 drops to about 1600 mega watts. The operators make a simple but fatal error by setting the regulator improperly.

April 26April 26thth, 12:28 am, 12:28 am
The power crashes down to only 30 mega watts. The reactor is becoming hard to control.

• Thirty-six seconds after the test had begun, the shift supervisor attempts to drop all control rods back into the reactor realizing the power was rising beyond its limits. In four and a half seconds, the power level inside the reactor rises 120 times the reactor's capacity.
• The first explosion broke the pressure tubes, releasing steam which blew the containment lid off the reactor.

The second explosion was the reactor fuel and graphite inside the core exploding, sending chunks of graphite and other radioactive elements flying. It destroyed the building, and caused more than 30 roof fires.

How did the country react?How did the country react?
• The morning after the explosion, there was no hint of a disaster.
• After 36 hours of be exposed to radiation, people were told to pack their clothing and evacuate their homes.
• There as was a 30 kilometer or 18 mile evacuation.

• Due to prevailing winds, it carried the radioactive particles around the world.

What about the environment?What about the environment?• At the nuclear power
station itself, several attempts were made to clear away and contain chunks of graphite and other radioactive solids.
• They sent in volunteers.• The volunteers were only
allowed to be in the power station for 90 seconds or less.
• The radiation levels were 15,000 times greater than a normal person's exposure in a year.

What about the environment?What about the environment?
• Any movable objects near the plant were buried; cars, trucks, and even topsoil.
• Some 60,000 buildings had to be washed with special chemicals, and even some roofs had to be replaced.
• A special solution was sprayed throughout the danger zone on streets and walkways to prevent radioactive dust from blowing and further contaminating the area.
• Nearby trees that had absorbed the radiation were all cut down and buried in concrete pits.

Is it still working?Is it still working?
• Chernobyl continued to produce electricity for another 14 years, until international pressure forced its closure in 2000.
• An official exclusion zone around the plant remains in place, extending for 30 kilometers (18 miles). It is one of the most radioactive spots on Earth.

• Water Pollution:– Radiation in Dnieper River will peak in 60 to
90 years, causing multiple problems• Water is already polluted

• Agricultural Problems:– Millions of acres of farmland have been
poisoned• Causes food shortages; hurts economy
