At the junction of the Mantaro and Yauli rivers in Peru, over 12,000 feet up in the Andes, is a small city of about 35,000 people. It is a community built on the mineral wealth of the mountains and exists only to serve the mines and the smelting company that processes the ore. In 1922 the Cerro de Pasco Corporation, A US-owned company with operations in South America, built a smelting plant in La Oroya, Peru. It was part of the expansion of North American and European corporate expansion into the resource-rich continent. A town grew up around the industrial complex.
The plant has changed hands many times over the years, including being owned by the Peruvian government from 1974 until 1997, when it was privatized and purchased by the Doe Run company of Missouri.
The plant gives off a list of toxins that includes high levels of lead, arsenic, cadmium, and zinc. A 1999 study of school children in La Oroya found that 99 percent of them were suffering from lead poisoning and 20 percent were so contaminated that they should have been hospitalized. They couldn’t be hospitalized because the facilities do not exist to treat such a large portion of the population, unfortunately.
Doe Run has taken some measures, though they are largely insufficient and seem more related to public relations than improving the lives of residents. Children under six years of age and having more than 45 micrograms of lead per decilitre of blood are bused to Casaracra, a 30 minute bus ride away, for eight hours a day. The World Health Organisation limit for lead is 10 micrograms per decilitre of blood, so to qualify the children have be 4.5 times the acceptable limit. Being removed from the environment for eight hours a day may reduce exposure somewhat, but the children still spend two thirds of their lives surrounded by emissions known to be toxic. The program also applies only to those six and under, leaving school-aged children exposed to the toxins 24 hours a day.
“Exposure to lead is more dangerous for young and unborn children. Unborn children can be exposed to lead through their mothers. Harmful effects include premature births, smaller babies, decreased mental ability in the infant, learning difficulties, and reduced growth in young children. These effects are more common if the mother or baby was exposed to high Center for Disease Control
Other pollutants, most notably cadmium, arsenic and sulphur dioxide, are also well above the acceptable limits set by the WHO. Children are not only more susceptible to the effects of exposure, but more likely to be exposed because they play in the dust and tend to put contaminated objects, such as toys, in their mouths.
As part of the privatization process, Doe Run was supposed to reduce toxic emissions and clean up the facility. In May 2006 Doe Run received its fourth extension to reduce toxic emissions and now has until 2009 to meet its targets. Given the lackadaisical attitude the company has exhibited so far, it is unlikely that it will do so without some sort of outside intervention.

The 2006 extension came in the wake of a civil court suit in which the Peruvian government was found at fault for failing to comply with the National General Health Law, the National Air and Environmental Quality Standards, and a Supreme Decree regarding declaring States of Emergency in cases of contamination.
Carlos Chirinos, the Peruvian Society for Environmental Law (SPDA) attorney who handled the case said, “This decision confirms the urgent need to implement measures to protect the health and lives of the people in La Oroya that are affected by the smelter. We will closely monitor compliance with the court order, to ensure improvements in the quality of life and health for the populace, and the economic benefits that this will bring to the region.â€

The Peruvian government has little power in their relationship with large companies. Not only does the government desperately need the revenue such companies provide, but the development and jobs are all that stand between many of the citizens and destitution. La Oroya is a perfect example of this kind of catch-22.
The land surrounding the complex is incapable of supporting crops. It is high in the mountains, where few crops can survive. It was marginal before the toxins released by the plant were a factor and is now incapable of supporting any sort of crop. The jobs that aren’t directly related to mining and smelting are spin-offs of those industries. Without the Doe Run plant, there would be no stores, schools, daycare, or medical facilities.

La Oroya supports about 35,000 people locally but it also supports many more in various other parts of Peru. Office workers, executives, hotel and restaurant workers and a variety of others across the country depend on the mining and smelting industry for their incomes. To close down a major facility would be a severe economic blow and is not a viable option. So when Doe Run asks for an extension from the Peruvian government, it gets an extension.
Doe Run has also arguably made things better than when the plant was run by the Peruvian government. Lead emissions have been reduced by 35%, sulphur dioxide emissions by 5%, and waste water treatment has been improved. There have been attempts to recover land formerly contaminated by slag heaps.

Emissions are still well above limits set by the WHO and the Peruvian government though. If Doe Run’s La Oroya operation were subject to the same laws they have to comply with in the United States, they would be forced not only to drastically reduce their emissions, but to clean up the surrounding area to a much larger degree than they already have.

Given the greatly reduced costs of operating in countries such as Peru, with their reduced wage and operating costs, there is little excuse for the continued contamination of La Oroya and its citizens. The kind of procrastination and evasion practised by companies like Doe Run in the developing world would never be tolerated in the developed world. Doe Run was forced to clean up its Herculaneum, Missouri operation. Why not La Oroya?
I have just returned from a trip to La Oroya and am in complete dismay to see how much teh Peruvian Company, Doe Run, seems to be misinforming the public. Sure some action has been taken, but when such a large percent of the children there are forced to live in an enviroment that is slowly killing the children, more action is obviously needed. Doe Run is the economic base of this community and the company and the people are aware of this, but that should now allow the company to bypass nationally set standards and continually be given extensions on their contracts formed back in 1997, when the company was bought.
POLLUTION TO THE OROYA CITY PERÚ
The years 2006 and 2007 the Blacksmith Institute have accomplished a research about the cities more contaminated to the world and arrived to the conclusion that the Oroya city was between the 10 cities more polluted of the world and, the environment Graffiti 2008 said that is between five more pollute too to the world. This qualifications are benevolents; according to my researchs to many years who I am publishing, the Oroya city is the most polluted to Peru, Latin America and of the world and every day is being more polluted: lead in blood in children in the Ancient Oroya in average 53.7 ug/dl ( DIGESA 1999); pregnancies women 39.49 ig/dl ( UNES 2000), new borns children 19.06 ug/dl, puerperal 319 ug/100 grams/placenta ( Castro 2003) and workers 50 ug/dl ( Doe Run 2003).Top lead in blood accepted 10 ug/dl; present day is 0 ug/dl ( Pediatric of Academy to USA)
When the Oroya city was in hands to the CentroMin eliminated only by the upper chimney to 167.500 meters, in average by day in tons: sulfur dioxide 1000, lead 2500, arsenic 2500, cadmium 40, particulate matter 50 and so on, more 24,000 to toxis gas product to the incomplete combustion of the coal, without count it is eliminated by industrial incinerator y by the 97 smalls chimneys, it is estimated 15,000; overall 45,000 tons for day (PAMA . El Complejo Metalúrgico de la Oroya, 1996); other research say that by this chimney only eliminate overall 119¨917,440 tons too every day to a velocity to 8.7 meters by second ( Chuquimantari C. Yauli-La Oroya Minería y Ciudades Empresas Pág. 57, 1992)
Doe Run envoy every three months the concentrations of the heavy metals to the Ministry to the Energy and Mines and with the sames datums Ceverstav have demostrated the pollution was increased; for example the sulfur dioxide it have increased in near to 300 %, by increment to the production (Cederstav. La Oroya no Espera 2002
The American Association to the Environment say that the environmental quality to the Oroya it is serious deteriorated since that Doe Run was owner and the same enterprise
declared that the concentrations of the heavy metals gas is ncreased in the air: lead 1160 %, cadmium 1990 % and arsenic 6006 % (Portugal, et al. Los Humos de Doe Run 2003)
