Hugh Pickens writes "Blacksmith Institute has published their list of the most polluted sites in the world compiled by comparing the toxicity of the contamination, the likelihood of it getting into humans and the number of people affected. For example, ninety-nine percent of the children living in and around the poly-metallic smelter at La Oroya in Peru, owned by the Missouri-based Doe Run Corporation, have blood lead levels that exceed acceptable limits. Scientific American says that despite the massive pollution, it would be relatively cheap and easy to clean up the most dangerous hazards. For $15,000, the radioactive contaminated soil from the Mayak plutonium facility on the shore of the Techa River in the Russian town of Muslyomova could be dug up, saving an estimated 350 lives. 'For about $200, the cost of a refrigerator, we are able to save someone's life,' says Richard Fuller, founder of Blacksmith."
