It was around four in the morning when the calling bell rang at D.K. Satpathy’s home in Idgah Hills on 3 December 1984.
“Try to reach the mortuary as soon as possible, there are casualties beyond our imagination,” was the message received by Satpathy, then a 35-year-old forensic doctor with the state government’s Hamidia Hospital.
On the way to the mortuary, Satpathy saw that the entire campus of the adjacent Gandhi Medical College was flooded with people who were visibly ill. Some were gasping, others were vomiting, and most were weeping.
Scores of others lay dead. Doctors were giving the patients symptomatic treatment. The casualty medical officer informed Satpathy that around midnight, people started coming in with burning eyes, breathlessness and nausea.
Unknown to Satpathy and his colleagues, four hours earlier, about 40 tonnes of methyl isocyanate (MIC) gas, along with other chemicals, had leaked into the atmosphere of Bhopal from the Union Carbide India Ltd factory, which was surrounded by several heavily inhabited settlements.
The leak of the poisonous MIC gas, the main ingredient in Sevin pesticides manufactured by Union Carbide, was caused by a backflow of water in tank E610 at the factory. It is now recognized as the worst industrial disaster in history.
By the end of the night, the lethal gas had spread across an area of around 8 sq. km. By the end of 3 December, Satpathy says he had performed autopsies on 876 bodies. By the end of December, this number rose to 1,300.
By 1996, Satpathy had performed autopsies on 11,000 bodies, all related to the gas leak. That night, Satpathy was informed, someone from the hospital had called up the medical officer of Union Carbide factory.
“It is just tear gas. Just wash their eyes and mouth with water. It will affect patients only mildly,” the medical officer had responded. By the time Satpathy reached the mortuary on the morning of 3 December, there were nearly 500 dead bodies there.
Satpathy cleared his head. His mission as a forensic expert was to identity the person, carry out the post-mortem, ascertain the cause of death and fix responsibility. There were four forensic experts at the hospital.
It seemed like an impossible task to complete autopsies on so many bodies, so they decided to choose a random sample because the symptoms were similar and they had died in similar circumstances.
The remaining bodies were merely examined externally. Each dead body was photographed. Most were unclaimed and unidentified. Without exception, every person had died of respiratory failure; there was froth in their mouths and noses, serious pulmonary damage, their eyes were red, and their skin had rashes.
Satpathy found one peculiarity: the blood in both the veins and the arteries of the bodies was red, whereas, usually that in the veins is darker. “One of the chemicals that can cause this is cyanide,” he says. The next day, Satpathy and the other doctors were informed that the leaked gas was MIC; the team stored all the collected tissue and the blood.
Meanwhile, a German scientist, Don Derreira, who had arrived in Bhopal to establish that the tissue and blood had elements of MIC, informed the doctors that the appropriate treatment for exposure to MIC was sodium thiosulfate—administered intravenously—which would cause all the toxic elements to pass out through urine.
All the tissues were analysed and upto 22 compounds were isolated, out of which all but two were identified. All 22 compounds were also found in tank E610. “This tank was responsible, the owner was the culprit. We had linked the responsibility of the deaths. We also suggested the treatment. Our job was done,” says Satpathy.
Medical research terminated “There was much misleading on the part of Union Carbide. Apart from initially claiming the leaked gas was tear gas, they also claimed that MIC could not cross the placental blood barrier of a pregnant woman to affect the foetus,” says Satpathy, now 66 and retired, sitting at the forensic museum at the Medico-Legal Institute in Bhopal that is currently exhibiting pictures of postmortems conducted by him.
Satpathy had performed an autopsy on the body of a woman who was two months pregnant, and he found that the traces of chemicals found in her were also present in the foetus. The government showed appalling negligence toward medical and scientific research which should have been carried out to find out more about the unknown effects of MIC on the human body.
In 1985, more than 20 clinical and non-clinical research projects were sanctioned on MIC’s effect on the foetus, endemic areas, and health. But all the projects were terminated by 1990, after the completion of only two or three studies. “These studies could have been crucial because even (the) third and fourth generation could face the consequences; even genetic mutations can take place. But we were a complete failure in that regard,” says Satpathy.
“God forbid something like this happens again with the same gas—we will still not know the ABC of how to manage the disaster.” Samples were collected from the bodies and sent for analysis to various labs across the country, including the All India Institute of Medical Sciences in Delhi. “It was very hard for us to preserve the tissue in a refrigerator for 30 years, for nothing.
One time, the fridge was out of power, and some tissue samples were completely decomposed,” Satpathy says Many of the foetuses from pregnant women killed in the disaster are still lying preserved at Gandhi Medical College in Bhopal, and the tissues are preserved in formalin. “They can be used for analysis, but no one is interested,” says Satpathy, pointing to an unresolved legacy from the world’s worst industrial tragedy.
