Four decades of horror after India's Bhopal gas disaster

Just after midnight as poisonous plumes of smoke wafted through the Indian city of Bhopal four decades ago, Gas Devi was born, gasping for every breath.

Her feeble cries were drowned out by the screams of men, women and children as they ran to escape the cloud of highly toxic gas leaking from the Union Carbide factory on the night of December 2, 1984.

Some 3,500 people were killed in the immediate aftermath, and up to 25,000 are estimated to have died overall in the world's deadliest industrial disaster.

Forty years later, the horror continues to blight the lives of those like Devi - as well as countless others born with deformities since that fateful night.

Devi, a daily wage labourer, has constant pain in her chest, one of her lungs is not developed fully and she keeps falling sick.

"My life is a living hell," Devi said, speaking at her shanty in Bhopal, the capital of the central state of Madhya Pradesh.

Even if she wanted, she cannot forgot the night she was born.

"My parents named me Gas," she said, her eyes welling up. "I believe this name is a curse. I wish I had died that night".

Twenty-seven tonnes of methyl isocyanate (MIC), used in the production of pesticides, swept through the city of over two million people after one of the tanks storing the deadly chemical shattered its concrete casing.

As the white cloud of MIC shrouded areas close to the factory, people started collapsing in the streets.

Nathuram Soni, now 81, was among the first to rush out.

"People were frothing from their mouths. Some had defecated, some were choking in their own vomit," said Soni.

A handkerchief tied over his nose, Soni used his pushcart to carry his wailing neighbours, many of them infants, to the hospital.

Unrelenting tragedy

Rashida Bee, co-founder of the Chingari Trust charity that offers free treatment to children of gas-affected families, believes those who died were fortunate.

"At least their misery ended," she said. "The unfortunate are those who survived".

Her trust has seen more than 150 children being admitted this year alone with cerebral palsy, hearing and speech impairments and other disabilities.

She blames the disorders on the accident and the contamination of the groundwater.

Testing of groundwater near the site in the past revealed cancer- and birth defect-causing chemicals 50 times higher than what is accepted as safe by the US Environmental Protection Agency.

"This tragedy is showing no signs of relenting," said Rashida, 68, who has lost several members of her family to cancer since the accident.

"The soil and water here are contaminated - that is why kids are still being born with deformities."

Union Carbide, which was acquired by the Michigan-based Dow Chemical Company in 2001, routinely dumped chemical waste years before the disaster, campaigners say.

Large evaporation ponds outside the factory were filled with thousands of litres of liquid waste.

Toxins penetrated the soil and the water supplying several neighbourhoods.

No legal mechanism

A plea seeking compensation of 500,000 rupees ($5,920) from the Indian government for each victim diagnosed with cancer or kidney ailments is languishing in courts.

Rachna Dhingra, a social activist from the Bhopal Group for Information and Action, said true justice still evades the survivors.

"Until today, not a single individual has gone to jail - even for a day - for killing more than 25,000 people and injuring half a million people, and contaminating the soil and groundwater," she said.

"People in the city are continuing to fight because there is no legal mechanism to hold these corporations accountable worldwide.

"Bhopal has taught corporations how to get away with murder."
