Top Ten most Polluted Places

Sumqayit in Azerbaijan gained the dubious distinction this week of being added to Blacksmith Institute's top 10 list of the world's most polluted sites. Yet another heir to the toxic legacy of Soviet industry, the city of 275,000 souls bears heavy metal, oil and chemical contamination from its days as a center of chemical production. As a result, local Azeris suffer cancer rates 22 to 51 percent higher than their countrymen and their children suffer from a host of genetic defects ranging from mental retardation to bone diseases.

"As much as 120,000 tons of harmful emissions were released on an annual basis, including mercury," says Richard Fuller, founder of Blacksmith, an environmental health organization based in New York City. "There are huge untreated dumps of industrial sludge."
