1984- Bhopal Gas Leak, India Occurred on the 2-3rd of December, 1984 in Bhopal, India.
It occurred at the Union Carbide India Limited (UCIL) pesticide plant over night.
Caused by a leak in the piped, which occurred because of poor maintenance and lack of routinely pipe checks. A factory that produced pesticides leaked a poisonous gas called methyl isocynate and a whole range of fatal chemicals into the atmosphere, creating a dense toxic cloud over the region. The accident has been referred to as the worst industrial accident of all time. It killed over 8,000 in two weeks.
Describes as the world’s greatest industrial accident, the gas leak caused over 16,000 people with at the least 550,000 injuries. Instead of being cleaned up, the accefted area was converted into a dumping ground for chemicals.
The UCC was convicted and blamed for the gas leak, and was mined millions of dollars.
1986- Chernobyl nuclear accident
Occurred on the 26th of April, at the nuclear power plant in Chernobyl, Ukraine.
Overheating of the reactors, which caused an explosion and a fire that released radioactive particles into the atmosphere. Radioactive clouds formed, and spread across vast areas of Europe.
The clean up of the accident included 500,000 workers and 31 people died from the explosion.
Increased chance of cancer development and gene mutation in humans.
- The site is still too dangerous for human life
-Thousands of people died due to illnesses caused by the radiation
-The rate of cancers and birth defects increased dramatically
-Higher death rates in affected areas

...e 6 nuclear reactor in the plant melted down. It is the largest nuclear accident since Chernobyl. 15,884 people died in that area as a result of the meltdown and the earthquake that preceded it. 300,000 people were evacuated form the area. The incident is expected to take decades to clean up. Many people’s chances of developing caner were increased as a result of the massive radiation released by the incident. Japanese authorities implemented a 20km2 exclusion zone around the affected area.
The radiation near the affected area caused a higher risk of different cancers in people (namely leukaemia and thyroid)
Soil in the area has been exposed to radiation, which means that it’ll take years and years until crops can be grown once again in that area. Contaminated water made its way into the rivers and oceans, contaminating marine life, making it dangerous to eat.
...r. Iodine 131, another radioactive element, can dilute very quickly in the air, but if it is deposited on grass eaten by cows, the cows then re-concentrate it in their milk. Absorbed into the body's thyroid gland in a concentrated dose, Iodine 131 can cause cancer. In the Chernobyl disaster, the biggest health effect has been cases of thyroid cancer especially in children living near the nuclear plant. Therefore, because of the Chernobyl disaster we know to test the grass, soil, and milk for radiation. Also, an evacuation of the Chernobyl area was not ordered until over 24 hours after the incident. Japanese authorities evacuated 200,000 people from the area of Fukushima within hours of the initial alert. From the mistakes and magnitude of the disaster at Chernobyl, the world learned how to better deal with the long and short term effect of a Nuclear Fallout.
On April 26th, 1986, operators at the Chernobyl Power Plant in Chernobyl, Ukraine, ran what they thought to be a routine safety test. But fate was not on the side of these operators. Without warning, reactor #4 became unstable, as it had been operating at a low power for a possible shutdown and the reactor’s design caused it to be unsafe at this level of power. Internal temperatures rose. Attempts to cool the system produced the opposite effect. Instantly, the nuclear core surged with power. At 1:23 p.m., the reactor exploded. The first blast ripped off the reactor's steel roof. The second blast released a large plume of radiation into the sky. Flames engulfed the building. For ten long days, fire fighters and power plant workers attempted to overcome the inferno. Thirty-one of them died of radiation poisoning. Chernobyl was the worst nuclear disaster in history. It unleashed radiation hundreds of times greater than the atomic bombs exploded over Japan during World War II. [1]
The Meltdown happened at 1:23 AM, beginning a fire that scattered vast amounts of radioactive materials into the air. The measure of radioactive material discharged was 400 times more than the sum the nuclear bombing of Hiroshima discharged. The aftermath was being recognized in all parts of Europe, especially some parts in Asia.
British Petroleum (“BP”) is the company that is being blamed for the incident. Employing 80,000 people, BP is an international oil company that puts different technology to use for finding oil and gas under the Earth’s surface. One of the oilrigs, Deepwater Horizon has drilled 35,000 ft. making it to be the deepest drilling of oil and gas (Walsh). Deepwater Horizon was drilling in the Gulf of Mexico about 52 miles southeast of Venice on Louisiana's tip. After the explosion, helicopters searched for 11 crewmembers that reported missing. 17 people were injured (BP Internal Investigation Team). A day later, the rig was found upside down (BP Oil Spill Timeline). The cost to clean up the damage is approximately $760 million (Walsh).
Hopefully, with accurate analysis and innovation, my research will teach the world of its past so this disaster doesn’t occur in the future. B - Summary of Evidence Chernobyl (chrn byl) is an uninhibited city in north Ukraine, near the Belarus boundary, on the Pripyat River. Ten miles to the north, in the town of Pripyat, is the Chernobyl nuclear powerstation, site of the worst nuclear reactor disaster in history ("Chernobyl", Columbia Encyclopedia). To specify, on April 26, 1986, Unit Four of the Chernobyl nuclear reactor exploded in Ukraine, injuring human immune systems and the genetic structure of cells, contaminating soils and waterways. Nearly 7 tons of irradiated reactor fuel was released into the environment—roughly 340 million curies.
"The tops are leaping off the reactor lip" this was the first warning which the control room received before the destructive explosion in Chernobyl that occurred at 1:23 AM local time. Twenty three minute after the warning in the morning of 26 April 1989, the reactor exploded. The Chernobyl nuclear accident was an unexpected catastrophe that can happen in the history of producing nuclear power. International Atomic Energy Agency (IAEA) defined a nuclear accident as an accident that includes any activities that lead to the release of radioactive material and causes significant consequences. The location of Chernobyl city is in the north of Ukraine near the Belarus border. That nuclear accident happened when in reactor number 4 in the Chernobyl nuclear power in the Soviet Union exploded. Because of that extreme explosion, the radioactive emissions dispensed into the environment and caused immediate deaths, illnesses and many health problems. World Health Association (2013) reports that during the accident, one person died immediately and another one died in the hospital due to the harmful injuries he received. Health World Organization (WHO) (2006) also reports that a few weeks after the disaster 28 people died because of the Acute Radiation Sickness(ARS). The Chernobyl nuclear accident is one of the major disasters in the history of nuclear power which had many serious effects on humans and the environment.
It was clear that the governments in America would not issue a permit to Union Carbide plant under such circumstances, which lacked severe environmental standards and permitted slum dwellers to live near the plant and so on. Such actions were the ones that led to more deaths. Before the major gas leakage from the MCI unit on December 3, 1984, some people were killed because of phosgene gas leakage. However, no one took it seriously, despite the media report. One of the reasons that people ignore this was because people didnt know the potential danger of the chemical plant.
Accidents are an inevitable part of life. Children learn this at an early age by bumping their head, scraping their knees, or falling off the swings. They learn that sometimes painful experiences just happen, seemingly without cause or reason. These children carry these lessons into adulthood, and then project their tolerance for accidents onto their families and occupation. The chemical industry, while one of the safest industries, has the potential for catastrophic accidents. Through experience and renewed focus on the conservation of life, the chemical industry has improved its safety considerably. In 2005, chemical industry fatality rate (the number of fatalities per year per total number of people in the applicable population) was the third lowest when compared to industries such as agriculture, coal mining, and construction1. However, accidents still occur, sometimes with regrettable repercussions. In 2005, Formosa Plastics Corporation in Point Comfort, Texas experienced an accident with severe consequences.
Radiation exposure can affect children as well an children have the risk of being the most harmfully effected by radiation because their body absorbs substances differently also their bodies can or are more likely to get certain kinds of cancers from too much exposure, “they are also closer to the ground, where radioactive fallouts settle.”
Chernobyl was the greatest nuclear disaster of the 20th century. On April 26th, 1986, one of four nuclear reactors located in the Soviet Union melted down and contaminated a vast area of Eastern Europe. The meltdown, a result of human error, lapsed safety precautions, and lack of a containment vessel, was barely contained by dropping sand and releasing huge amounts of deadly radioactive isotopes into the atmosphere. The resulting contamination killed or injured hundreds of thousands of people and devastated the environment. The affects of this accident are still being felt today and will be felt for generations to come.
One of the most significant environmentally damaging instances in history was the Chernobyl incident. In 1986, the Chernobyl Nuclear Plant in Ukraine exploded. It became one of the most significant disasters in the engineering community. There are different factors that contributed to the disaster. The personnel that were tasked with operating the plant were unqualified. The plant’s design was a complex one. The RBMK reactor was Soviet design, and the staff had not be acquainted with this particular design. As the operators performed tests on the reactor, they disabled the automatic shutdown mechanism. After the test, the attempt to shut down the reactor was unsuccessful as it was unstable. This is the immediate cause of the Chernobyl Accident. It later became the most significant nuclear disaster in the history of the
On the summer of 2010, the petroleum industry was shaken by one of the largest disasters in history known as the BP Deepwater Horizon Oil Spill. This resulted in the killing of eleven people, injuring of seventeen and an immeasurable damage to the ocean and the surrounding communities. BP had to immediately respond to the crisis and handle their financial and reputational risks.
One of the worst cases of catastrophic event in history is the Bhopal Union Carbide case.
Just after midnight on 3 December 1984, a dense gas cloud formed and rolled through the city of Bhopal and its surrounding villages. The people that inhaled the gas immediately started feeling its affect. They coughed uncontrollably, the gas burning their eyes, noses, and throats. The gas then attacked their central nervous system and, if they were unable to escape the cloud, they fell dead.
On April26, 1986, the nuclear power plant was exploded in Chernobyl, Ukraine. At 1:23 AM, while everyone were sleeping, Reactor #4 exploded, and 40 hours later, all the city residence were forcefully moved to other cities, and they never return to their home. The Chernobyl disaster is ranked the worst nuclear accident. The Chernobyl nuclear power plant was ran by the Soviet Union central nuclear energy corporation.
