  • Convulsions
how did they fix the problem
How did they fix the problem?
  • Kumamoto University began to research the disease
  • Found animals with same problems realized it dealt with food
  • Fish main diet traced back to ocean
  • Compensation of patients
  • Wastewater treatment
prevention
Prevention
  • Prevention of Pollution-related Health Damage
  • Rules and regulations for pollution and dumping into the ocean
  • Companies like Chisso under more scrutiny
status
Status
  • Water and food sources have been cleaned
  • Now facing pollution from other sources like nuclear reactors
  • Regulations placed on fishing industry
the london fog

The London Fog

By:

Ashley Aviram, Paul Park, DaniellaShoenburg

why did this occur
Why did this occur?!?!?
  • A mass of stagnant air had collected above the sky of London, trapping all the pollutants in the air
  • The cold weather present during that time meant millions of Londoners would be burning more coal than usual
  • Vehicle exhaust also contributed to the pollution, especially the diesel-fueled buses
environmental effects
Environmental Effects :(
  • Poor visibility – people could not see past a few yards

I cant see!!!!

effects on humans1
Effects on Humans :(
  • An estimated 12,000 people died
  • Most of the victims were young, old, or had had respiratory problems
  • About 25,000 people became ill
solutions
Solutions?!?!?!?!
  • Luckily, a change of weather removed the stagnant air and the Big Smoke dispersed

YAYYYYYYY!!!!!

prevention1
Prevention!!
  • New regulations were created to restrict the use of dirty fuels and black smoke
  • Clean Air Act of 1956 and 58
    • banned emissions of black smoke
    • residents of urban areas and operators of factories must convert to smokeless fuels
currently
Currently?
  • The London Fog lasted only from 12/5/52 to 12/9/52, so it does not exist today 
  • Smog is also less prominent due to the new laws 

chernobyl ukraine

Chernobyl, Ukraine

Nuclear Disaster

slide29
Maps

hi

Chernobyl nuclear power plant is located in Ukraine, 20km south of the border with Belarus.

causes of disaster
Causes Of Disaster

26 April 1986

  • Caused by inexperienced staff working at the Chernobyl Power Plant
  • The staff wanted to test reactor 4 but another power plant went down
  • The Chernobyl plant had to produce more power than it was supposed to so it could compensate
  • The night staff who were less experienced thought they could test the reactor, but did not know that you couldn’t test while it was producing double the power
  • The emergency shutdown mechanism couldn’t stop the plant, and their Geiger counters weren’t advanced enough to tell them how high the radiation levels were
  • The crew stayed 3 days after the explosion not knowing the high radiation levels, as they were attempting to pump water into the reactor to control it
effect of disaster on the environment
Effect Of Disaster On The Environment
  • Largest uncontrolled radioactive release in environment residentially and large amounts of radioactive substances released into the air
  • Deposited in the urban areas near the power plant
  • The deposition of radioactive iodine contaminated agricultural plants, grazing animals
  • Particularly contaminated mushrooms and berries
  • Radioactive materials from Chernobyl deposited on rivers, lakes and some water reservoirs
  • The radioactive materials released by the accident had immediate harmful effects on plants and animals living within 20 to 30 km of the Chernobyl power plant
effect of disaster on humans
Effect Of Disaster On Humans
  • The current death toll =1 million people
  • Around 1800 children ages 0 to 14 were diagnosed with Thyroid Cancer
  • Up to 2.4 million Ukrainians had negative effects on their health
  • Explosion effected all of Europe
  • Higher rates of Birth defects have been linked to disaster
what is being done to fix this problem
What Is Being Done To Fix This Problem?
  • During the first years, settlements in contaminated regions of the USSR were cleaned up at a very high cost
  • In order to reduce long term contamination of milk and meat with radioactive cesium, the animals were fed crops that would trap the radioactive chemicals
  • Between May and November 1986, a Shelter was built to contain the damaged reactor to prevent further release
  • The overall plan for the long term development of the Exclusion Zone is to make the less affected areas available for use by the public.
prevention of future disasters
Prevention Of Future Disasters
  • The Soviet Union and, later, the Commonwealth of Independent States (CIS) spent large amounts of money to deal with clean-up and repair.
  • To prevent the release of more radiation a Shelter was quickly built to contain the damaged reactor. (Problems become apparent with the first shelter and a new “more durable” shelter is being built.)
  • New Safe Confinement (NSC) should provide more than 100 years of service life and is planned to cover over the existing Shelter.
current environmental status of area
Current Environmental Status Of Area
  • Large amounts of radioactive waste was generated and placed in temporary near-surface waste storage and disposal facilities.
  • An “exclusion Zone” was created extending up to 30 km in all directions around the Chernobyl nuclear power plant.
  • Restrictions have been placed on fresh water, hunting, and forest products (berries, mushrooms, and firewood) in the areas surrounding Chernobyl.
  • Since the disaster, the radiation levels have reduced significantly, but are still very high.
  • Although some animals have returned, very few people go there.

      • Hair loss, nose bleeds, fever, nausea, death, etc.
  • Feelings of fear, confusion, and hatred
what is being done to fix the problem
What is Being Done to Fix the problem?
  • Hiroshima was rebuilt after the war
  • Proclaimed a city of peace

Atomic Dome

prevention3
Prevention
  • International Atomic Energy Agency established to encourage peaceful applications of nuclear tech

environmental status
Environmental Status
  • Background radiation now at normal levels
  • Population today-about 1.12 million
  • City was rebuilt and is a major urban center

Kill a Sparrow Campaign

Presented by: Rebecca Nourafshan, AriellaMahgerefteh, and Ashley Emrani

slide48

Map of China

China was the country which was affected by the “Kill a Sparrow Campaign”

slide49

Causes of Disaster

  • Initiated in 1958 as a hygiene campaign by Mao Zedong
  • Zedong identified the need to exterminate mosquitoes, flies, rats, and sparrows
  • Tried increasing rice yields
  • Culturally influenced by TVB drama series Rosy Business
  • -peasant came up with idea of killing sparrows to improve agricultural output
slide50

Effects of Disaster on Environment

  • Increase in insects and worms since their predators (sparrows) died off
  • One of China’s greatest locus invasions of history
  • Crops died from being eaten by an abundant amount of pesticides
slide51

Effect of Disaster on Humans

  • Famine
  • 30-43 million deaths resulted from starvation
slide52

What’s being done to Fix the Problem?

  • Mao ordered end  to campaign against sparrows replacing them with bed bugs
  • Too late
  • Locust population increases
  • Increases ecological problems caused by Great Leap Forward 
  •      -widespread deforestation
  •      -misuse of poisons and pesticides
  • Great Chinese Famine
  •      -more than 30 million died of starvation 
slide53

How to Prevent Future Disasters

  • This disaster was easily preventable
  • Humans shouldn’t get involved with nature
  • In the future, humans should allow natural regulation to take its course
slide54

Current Environmental Status of China

  • STILL did not stop: in 1998 had campaign to kill cockroaches instead of sparrows
  • June 19, 1998: poster at Southwest Agricultural University in Chongqing
  • Cockroaches instead of sparrows
  • Similar campaign in the spring of 1998 in Beijing
