Bhopal is the capital of Madhya Pradesh and is a city known for one of the world’s worst industrial disasters: the Bhopal Gas Tragedy.
In 2024, I had the opportunity to walk around the abandoned chemical plant in Bhopal. The site remains under guard as the facility and its surroundings are still heavily contaminated. The severity of this pollution became immediately clear as I approached the wreckage of the exploded tank, which continues to emit a sweet, organic solvent odour—suggesting the persistent presence of chlorinated benzene compounds.
Bhopal’s Disaster
On the night of December 2 in 1984, a catastrophic gas leak occurred at the Union Carbide pesticide plant in Bhopal, known for its production of the pesticide Sevin. A reaction inside a storage tank containing methyl isocyanate (MIC) caused a massive release of toxic gases. The dense gas cloud drifted over the neighbourhoods surrounding the plant, exposing hundreds of thousands of unsuspecting residents.
The consequences were devastating. Thousands died within hours due to the acute toxic effects. The official death toll is estimated to be around 3,800, but independent sources suggest that the actual number of fatalities could be significantly higher, reaching tens of thousands in the immediate aftermath and subsequent years due to related illnesses.
If the story of Bhopal’s disaster is new to you, I highly recommend to watch the “The Railway Men: The Untold Story of Bhopal 1984“, a great mini-series based on railway workers who saved many lives during the gas tragedy.
The Impact on Health
The Bhopal disaster has a lasting impact on the health of the affected population. The immediate effects included severe respiratory problems, eye irritation, burning sensations in the throat and lungs, vomiting, and death. Survivors suffered or still suffer from a range of chronic health issues.
The Impact on Environment
The massive release of toxic chemicals contaminated the soil, groundwater, and surrounding ecosystems. The abandoned plant site remains a source of contamination, with toxic waste leaching into the environment which had lead to soil and groundwater contamination, which results in indirect exposure of toxic compounds to the citizens of Bhopal and its surroundings. Remediation efforts have been slow and inadequate, leaving a source of toxic chemicals that continues to threaten the environment and the health of local communities.
Contaminants in Bhopal
While MIC was the primary chemical responsible for the immediate and direct cause of death directly after the leak, the high pressure and extreme heat within the storage tank triggered a “runaway” reaction. This caused the MIC to decompose into a toxic cocktail of secondary compounds. Furthermore, decades of substandard industrial waste management and the neglect of the abandoned facility have led to the corrosion of pipes and the failure of waste pond liners.
Chemicals that are known to have been released in the environment:
- Phosgene, classified as chemical weapon, precursor of MIC
- Methylamine, precursor of MIC
- Alpha-naphtol, A chemical used in conjunction with MIC to produce Sevin (Carbaryl)
- Organochlorines, Including Chlorobenzenes, Chloroform, and Carbon Tetrachloride, which served as solvents or were created as reaction byproducts
- Heavy metals such as Mercury, Cadmium, Lead, Chromium, Nickel
Many of these compounds remain persistent in the soil and groundwater today. The presence of heavy metals is of particular concern, as their bio-accumulation in the local population, especially children, causes irreversible neurological and developmental health effects.
Bhopal Today
Over four decades after the tragedy, Bhopal continues to grapple with its aftermath. Survivors and their families continue to fight for adequate healthcare, compensation, and environmental remediation. The abandoned UCIL plant still stands as a stark reminder of the disaster, a symbol of corporate negligence and governmental inaction.
The ongoing struggles include:
- Lack of adequate healthcare: Survivors still face difficulties accessing specialised medical care for their chronic health conditions.
- Inadequate compensation: Many survivors feel that the compensation they received was insufficient to address the long-term health and economic consequences of the disaster.
- Slow progress on environmental remediation: The cleanup of the contaminated site has been slow and inadequate, posing ongoing risks to public health and the environment.
- Children continue to be born with birth defects such as cerebral palsy, musculoskeletal abnormalities, and neurological disorders, a result of both the initial gas exposure and decades of exposure to chemical waste.
Actions
The Bhopal disaster prompted significant changes in industrial safety regulations and corporate accountability worldwide. The Bhopal Gas Tragedy serves as a reminder of the consequences of industrial negligence and the importance of prioritising safety, environmental protection, corporate and governmental accountability. It is crucial to remember this tragedy and continue working towards a future where such disasters are prevented and victims receive the justice and support they deserve.
In 2025, forty years after the devastating Bhopal Gas Tragedy, significant cleanup actions are finally underway. Following a court order, approximately 377 tons of hazardous waste have been removed from the former Union Carbide factory site and transported to a disposal facility in Pithampur for incineration. This operation involves meticulous planning and safety measures, with the toxic material sealed in specialized containers and transported in fire-resistant, leak-proof trucks. The incineration process is expected to take between three to nine months. While authorities have emphasized the safety of this method, activists have raised concerns about potential environmental risks, particularly regarding water contamination, at the new disposal site.
March of Justice
Each year, on the anniversary of the disaster, the streets of Bhopal fill with thousands of survivors and activists participating in a “March for Justice.” Carrying torches and photographs of the deceased, the procession moves toward the abandoned factory in a powerful act of remembrance. By uniting generations in a demand for dignity, the march tries to achieve that Bhopal’s struggle is never forgotten. In addition, it is one of the last ways to achieve justice in the Bhopal tragedy case for right compensation and adequate cleanup of the contaminated area. Ultimately, we must hope that corporations have learned from this disaster and that such tragic incident can never happen again.
