La Oroya, Peru
The World's Most Polluted Places
From lead in the soil to toxins in the water and radioactive fallout in the air, The Blacksmith
Institute has created a list of the world's worst ecological disaster areas.
La Oroya, Peru
Pollution from the mining and processing operations of Doe Run Peru has led to dangerously high concentrations of lead in children's blood in La Oroya.
MATHEW BURPEE
Number of people potentially affected: 35,000
Type of pollutant: Lead, copper, zinc and sulfur dioxide
Source of pollution: Heavy metal mining and processing
Lead is the contaminant that shows up most frequently on Blacksmith's list because the toll it takes on children can be so devastating. In La Oroya, a mining town in the Peruvian Andes, 99% of children have blood levels that exceed acceptable limits, thanks to an American-owned smelter that has been polluting the city since 1922. The average lead level, according to a 1999 survey, was triple the WHO limit. Even after active emissions from the smelter are reduced, the expended lead will remain in La Oroya's soil for centuries — and there's currently no plan to clean it up.
