World's Worst Polluted Places
by The Blacksmith Institute
La Oroya, Peru
Potentially affected people: 35,000
Type of pollutants: Lead, copper, zinc, and sulfur dioxide.
Site description: Since 1922, adults and children in La Oroya, Peru - a mining town in the Peruvian Andes and the site of a poly-metallic smelter - have been exposed to the toxic emissions from the plant. Currently owned by the Missouri-based Doe Run Corporation, the plant is largely responsible for the dangerously high blood lead levels found in the children of this community. Ninety-nine percent of children living in and around La Oroya have blood lead levels that exceed acceptable amounts, according to studies carried out by the Director General of Environmental Health in Peru in 1999. Lead poisoning is known to be particularly harmful to the mental development of children. A survey conducted by the Peruvian Ministry of Health in 1999 revealed blood lead levels among local children to be dangerously high, averaging 33.6 micrograms/deciliter for children between the ages 6 months to ten years, triple the WHO limit of 10 micrograms/deciliter.
Sulfur dioxide concentrations also exceed the World Health Organization emissions standards by ten fold. The vegetation in the surrounding area has been destroyed by acid rain due to high sulfur dioxide emissions. To date, the extent of soil contamination has not been studied and no plan for reduction of emissions has been agreed or implemented.
Numerous studies have been carried out to assess the levels and sources of lead and other metals still being deposited in La Oroya. Limited testing has revealed lead, arsenic and cadmium soil contamination throughout the town. However, all of these studies were focused on outdoor contamination and suspected severe indoor air pollution has not yet been assessed in detail..
Cleanup Activity
Peru's Clean Air Act cites La Oroya in a list of Peruvian towns suffering critical levels of air pollution, but action to clean up and curtail this pollution has been delayed for the 35,000 inhabitants. In 2004, Doe Run Corporation asked the government for a four year extension to the plants environmental management plan. A concerted NGO movement is now underway to pressure the company and the government to develop effective strategies for implementation of site remediation agreements and to provide health care for affected residents.
