Slide 1: 

Bhopal Gas Tragedy

PreviewAmongst the worst Industrail Disasters : 

PreviewAmongst the worst Industrail Disasters Occurrence: 3rd December 1984. Place of occurrence: Bhopal, Madhya Pradesh, India. Company: Union Carbide Corporation. Chemical: Methyl Isocyanate (27 tons)

Slide 3: 

Due to this disaster among the 500,000 people exposed to the gas, 20,000 have died till date and 120,000 continue to suffer devastating health effects as a result of their exposure.

Slide 4: 

The Bhopal Disaster

Slide 5: 

Bhopal Scenario Union Carbide Corporation

Slide 6: 

Started in 1969 in bhopal Phosgene, Monomethlyamine, Methyl Isocyanate (MIC) and the pesticide Carbaryl, also known as Sevin. Taken over by DOW Chemicals in 2001. DOW refused Union Carbide’s Liabilities in Bhopal, India. Union Carbide Corporation

Slide 7: 

How did this incident occur?

Slide 8: 

Union Carbide used MIC to produce a insecticide called Carbaryl MIC reacts with 1-naphthol in a hydrolysis process to produce Carbaryl What is MIC used for?

What is “MIC”(Methyl Isocyanate)? : 

What is “MIC”(Methyl Isocyanate)? Clear, colorless, sharp smelling liquid Highly flammable Extremely toxic Volatile reaction with water in about 10 minutes

Effective methods of obtaining Methyl Isocyanate:-Using a distillation column which uses a series of filtering devicesTreatment of MCC with a tertiary amine :

Methyl Isocyanate Physical and Chemical Characteristics : 

Methyl Isocyanate Physical and Chemical Characteristics Methyl Isocyanate (C2H3NO) Liquid form Volatile Colourless Strong, sharp odour Flash Point – -7oC Molecular weight: 57.05 daltons Boiling point (760 mm Hg): 102ºF (39.1ºC) Freezing point: -49ºF Vapor pressure: 348 mm Hg at 68ºF (20ºC) Vapor density: 1.42 (air = 1.00) Water solubility: Reactive 6.7% at 68ºF (20ºC) Flammability: Highly flammable Flammable Range: 5.3% to 26% (concentration in air)

Slide 12: 

Respiratory Disorders – Irritation to the lungs, causing coughing and/or shortness of breathing. Caused Asthama. Reproductive/Developmental Effects: After the Bhopal, India, accident, an unusually high percentage of survivors had disorders of the reproductive system, including leukorrhea, pelvic inflammatory disease, excessive menstrual bleeding, and suppression of lactation.  Other adverse effects included increases in the number of stillbirths, spontaneous abortions, and increased infant mortality. Animal studies have reported increased incidence of fetal deaths and decreased fertility, live litter size, fetal body weight, and neonatal survival following inhalation exposure to methyl isocyanate during pregnancy. Cancer Risk: In a study in which animals were exposed once by inhalation, no tumors were significantly associated with methyl isocyanate exposure in mice and female rats; male rats had marginally increased rates of tumors of the pancreas Effects on Human Health

Slide 13: 

Around 3000 animal were died Animal Slaughter

Chemicals Dumped by Union Carbide in Bhopal : 

Chemicals Dumped by Union Carbide in Bhopal

Haphazard dumping of Hazardous Material :

Toxic Materials in Soil and Water : 

Toxic Materials in Soil and Water

What happened to Union Carbide? : 

What happened to Union Carbide? After the Bhopal Disaster, the company went out of business. They were bought by Dow Chemical in 1999.

Remediation Process : 

Remediation Process Bhopal continues to suffer the environmental contamination produced by the release of MIC Donations and medical/volunteer assistance has been provided Union Carbide accepted responsibility and agreed to a $470 million settlement

What’s the situation now? : 

What’s the situation now? The Union Carbide location in Bhopal is not remediated. The plant still leaks toxic chemicals such as: Mercury Chlorinated organics Lead
