Thirty-two years after the world’s worst chemical disaster struck Bhopal, the city’s residents continue to be exposed to chemical toxins through soil, groundwater and air. Studies by Sambhavna Trust Clinic, which has been providing free medical care to 32,000 survivors, reveal that the contaminated area around the abandoned Union Carbide pesticide factory has increased by at least two square kilometres in the last four years...They said so long as thousands of tonnes of toxic waste remain buried in and around the factory, the contamination will continue to spread and find new victims.
