CASPIAN SEA _ AZERBAIJAN _SUMGAIT_ June 1997: An old factory with rusted machines. A pipeline secretes wastes onto the factory floor. Sumgait was once the industrial hub of chemical and heavy metal production in the Soviet Union. It had over 33 factories employing hundreds of thousands of workers, who were housed just one km from where the 300,000 tonnes of toxic waste produced each year was stored. Ten years after the collapse of the Soviet Union, 70% of the population has some form of chemical-related illness.
