One of the worst pollution crises in India was the 1984 Bhopal gas tragedy. A deadly chemical
leaked out of the Union Carbide factory, killing more than 2500 people and leaving thousands sick.
The effects of this gas tragedy are felt even today. Find out more about the tragedy. What were the
health effects on people exposed to the gas that leaked? Which judgment of the court in this case
led to an uproar in the country? Present your findings in the form of a presentation or a website.

Explanation:
It was on the night of December 2, 1984, when Bhopal died a million deaths. The chemical, methyl isocyanate (MIC), that spilled out from Union Carbide India Ltd’s (UCIL’s) pesticide factory turned the city into a vast gas chamber. People ran on the streets, vomiting and dying. The city ran out of cremation grounds. It was India’s first (and so far, the only) major industrial disaster. Till then, governments had handled floods, cyclones and even earthquakes. They had no clue how to respond in this case. The US-based multinational company, Union Carbide Corporation (UCC), which owned the plant through its subsidiary UCIL, did little to help deal with the human tragedy. Thirty years later, there is no closure. Not because of what happened that fateful night, but because our response has been incompetent and callous.
Bhopal was struck by two tragedies: the one that happened immediately, and the other that unfolded in the years that followed.
The problem was nobody knew much about the toxin or its antidote. Within weeks of the accident many claimed that the worst was over—that people were suffering from common ailments of the poor, such as tuberculosis and anaemia. But till date nobody knows the health impacts of MIC and how to treat patients exposed to the gas. The health burden is compounded by two more variables—one, children born after the disaster are also its victims because of exposure to the deadly gas while they were in their mothers’ wombs; two, chemical wastes remain dumped in and around the premises of UCIL factory, contaminating the water that people drink.

All this could have been managed if the government had information about the chemical and treatment for it. But even in 2014, all that the Indian Council of Medical Research (ICMR) in Delhi can say is the “exact causative agent of the Bhopal Gas Disease is unknown”. Why?
Union Carbide used trade secrecy as a prerogative to withhold information on the exact composition of the leaked gases. Though it was known that MIC, when reacts with water at high temperatures, could release as many as 300 highly toxic chemicals, research was carried out only to check the toxicity of pure MIC—that also on animals. So, the treatment has been symptomatic. This is criminal negligence. In the first few days, there was evidence that people could be suffering from cyanide poisoning—intravenous injections of sodium thiosulphate, an antidote, was found to be working on the patients. But soon, it was discontinued, many say, under pressure from UCC and its team of lawyers.
The diseases could also have been managed had the government conducted medical research to understand the long-term impacts of the gas. The responsibility was given to ICMR, which had initiated 24 studies.Some of the studies had found high incidence of lung, eye disease and morbidity in the victims. But the studies were summarily discontinued in 1994. All research work was left to Madhya Pradesh government’s Centre for Rehabilitation Studies, which did some uninspired research. Meanwhile, some independent studies had also pointed to serious health crises, from cancer and mental problems to birth defects. But since there is no epidemiological study, it is easy to dismiss these as ailments caused by poverty and lack of hygiene. This is when the Supreme Court has repeatedly asked for the patient records to be computerised and for studies to determine health impacts of this toxic exposure.
Explanation:
11.00 PM on December 2 1984, while most of the one million residents of Bhopal slept, an operator at the plant noticed a small leak of methyl isocyanate (MIC) gas and increasing pressure inside a storage tank. The vent-gas scrubber, a safety device designer to neutralize toxic discharge from the MIC system, had been turned off three weeks prior [3]. Apparently a faulty valve had allowed one ton of water for cleaning internal pipes to mix with forty tons of MIC [1]. A 30 ton refrigeration unit that normally served as a safety component to cool the MIC storage tank had been drained of its coolant for use in another part of the plant [3]. Pressure and heat from the vigorous exothermic reaction in the tank continued to build. The gas flare safety system was out of action and had been for three months. At around 1.00 AM, December 3, loud rumbling reverberated around the plant as a safety valve gave way sending a plume of MIC gas into the early morning air [4]. Within hours, the streets of Bhopal were littered with human corpses and the carcasses of buffaloes, cows, dogs and birds. An estimated 3,800 people died immediately, mostly in the poor slum colony adjacent to the UCC plant [1,5]. Local hospitals were soon overwhelmed with the injured, a crisis further compounded by a lack of knowledge of exactly what gas was involved and what its effects were [1]. It became one of the worst chemical disasters in history and the name Bhopal became synonymous with industrial catastrophe [5].
Estimates of the number of people killed in the first few days by the plume from the UCC plant run as high as 10,000, with 15,000 to 20,000 premature deaths reportedly occurring in the subsequent two decades [6]. The Indian government reported that more than half a million people were exposed to
toxic plume had barely cleared when, on December 7, the first multi-billion dollar lawsuit was filed by an American attorney in a U.S. court. This was the beginning of years of legal machinations in which the ethical implications of the tragedy and its affect on Bhopal's people were largely ignored. In March 1985, the Indian government enacted the Bhopal Gas Leak Disaster Act as a way of ensuring that claims arising from the accident would be dealt with speedily and equitably. The Act made the government the sole representative of the victims in legal proceedings both within and outside India. Eventually all cases were taken out of the U.S. legal system under the ruling of the presiding American judge and placed entirely under Indian jurisdiction much to the detriment of the injured parties.
UCC discontinued operation at its Bhopal plant following the disaster but failed to clean up the industrial site completely. The plant continues to leak several toxic chemicals and heavy metals that have found their way into local aquifers. Dangerously contaminated water has now been added to the legacy left by the company for the people of Bhopal [1,14].
