The Bhopal Tragedy, December 1984

Bhopal is the capital city of Madhya Pradesh. It is well known for its historical records, artificial lakes, and its amazing verdure.

Most of all, this city is vastly popular across the world for the worst industrial catastrophe that occurred 35 years ago.

A gas leakage engulfed the city of Bhopal, killing thousands and maiming many residents of the city to this day.


What Happened?


Nearly 40 metric tons of methyl isocyanate otherwise known as MIC, was released from a Union Carbide pesticide plant. This occurred on the night of December 2nd till December 3rd of 1984.

The leakage had taken place at Plant Number C of the Union Carbide factory in Bhopal. The night breeze that picked up the pace, bore itself with poisonous gas that was leaking from the Union Carbide factory overwhelming the city and residents of Bhopal. The deadly gas murdered both the awake and asleep. According to a testimony given by the government, approximately 3000 people died.




Cause:


Based on official records, methyl isocyanate (MIC) got infused with water that was used to cool the plant. This particular mixture of compounds led to the generation of volumes of gases that put a colossal amount of pressure in the Tank E610.

Eventually, due to the accumulation of enormous gaseous pressure the cover of the tank gave way, spewing out the deadly poisonous gas which overwhelmed about a 7-kilometer radius from the plant and affected approximately 200,000 of Bhopal’s population.

Some years after the tragedy, the Union Carbide Corporation filed in a scientific and legal investigative report stating that the cause of this tremendous disaster was sabotage. The UCC investigation proved that the disaster was in fact caused by the direct entry of water into the Tank E610 through a hose that was connected to the tank.



Effect:


The initial effects of exposure to this deadly gas were a cough, severe eye irritation and suffocation, a burning sensation in the respiratory tract, shortness of breath, stomach aches and vomiting. The primary causes of death were choking, reflexogenic circulatory collapse and pulmonary edema which was caused by the inhalation of the lethal poisonous gas.

It is estimated that over 100,000 to 200,000 residents have permanent injuries. The reported mishaps that followed were birth defects among children born to affected women, respiratory difficulties, cardiac failure secondary to lung injury, immune and neurological disorders.

The wildlife surrounding Bhopal were also affected by the lethal poisonous gas and an extensive number of animals were found dead and needed to be removed before further contamination could occur. 







Post-Leakage:


Residents who turned to hospitals were unaware that the doctors who were present in Bhopal were clueless to a situation like this. The doctors had a lack of knowledge of this gas and the symptoms of methyl isocyanate exposure were not immediately identified. 

Based on reports, the two hospitals in Bhopal treated an approximate amount of 50,000 patients. Official reports state that the leakage was contained within 8 hours but Bhopal, to this day, has not recovered and are feeling its permanent effects.

According to Human Rights Groups, thousands of tons of hazardous waste remain buried underground, and the government has conceded the area to be contaminated. There have been no known reported researches to conclusively prove that birth defects are directly related to the drinking of the contaminated water.  






  
Till this very day, the deadly effects of methyl isocyanate are felt all across Bhopal. It has affected the second and third generation of Bhopal's residents. 

Methyl Isocyanate is an organic compound with the molecular formula of CH3NCO. It is an intermediate chemical in the production of carbamate pesticides such as carbaryl, carbofuran and methomyl.  As a highly toxic irritant, it is extremely hazardous to human health. Methyl Isocyanate is colourless, poisonous, lachrymatory and flammable. This compound is extremely toxic and its threshold limit is set at 0.02 ppm by the American Conference on Government Industrial Hygienists. Exposure by inhalation, ingestion and contact in quantities as low as 0.04 ppm would be considered toxic. Exposure symptoms includes coughing, chest pain, dyspnea, asthma, eye, nose and throat irritation and skin damage as well. At higher levels of exposure, over 21 ppm, the severe results are pulmonary edema, hemorrhages, bronchial pneumonia and death. Storage of this compound is to be taken seriously and with utmost care. Stainless glass or glass containers may be safely used and is to be stored at temperatures below 40 degrees, preferably at 4 degrees.

  1. It truly was a tragedy. Still in shock about the amount of lives that were affected - 200 000 is an extremely large number.

The Seveso Disaster, 1976

The Seveso Disaster was an industrial accident that took place on the 10th of July, 1976. The accident took place in a small chemical manufacturing plant which is approximately 20 kilometres north of Milan in the Lombardy region of Italy. It is called the Seveso Disaster because Seveso, a community populated with 17,000 residents in 1976, were the most affected by this catastrophe. Neighbouring communities that were also affected are located in Meda, Desio, Cesano Maderno, Barlassina and Bovisio Masciago. The industrial plant was located in Meda and was owned by the company Industrie Chimiche Meda Societa Azionaria or otherwise recognized as ICMESA. Residents did not perceive the factory to be a source of danger since the factory had been there for many years. In 1969, the factory produced 2,4,5-trichlorophenol (TCP),  a by-product used mainly in the preparation of an acid. The derivatives which are used as herbicides and the preparation of an antibacterial ...

HUMIC ACID FOUND IN SOIL REDUCES ANIMAL DEATHS An acid found rich in hummus soil breaks down the misfolded proteins called prions that cause chronic wasting diseases. Prions are misfolded proteins which characterize several fatal neurodegenerative diseases in animals and humans. These malformed versions of proteins affect the nearby normal proteins to take on its complex shape and is harmful to the nerve cells. Infected animals become disoriented, and are unable to chew food or drink water months before death. Chronic wasting disease is an incurable neurodegenerative disease. It has killed large populations of deer, elk and moose. This has been spread across several countries such as South Korea, Sweden and Norway.  Deers are prone to be infected when they graze in prion contaminated areas. The discovery of how humic acid affects prions makes it easier to curb this disease.  Humic acid is a substance that is found naturally in soil. It binds to a p...
