Protecting the health of La Oroya's residents from toxic pollution
For more than 20 years, residents of La Oroya have been seeking justice and reparations after a metallurgical complex caused heavy metal pollution in their community—in violation of their fundamental rights—and the government failed to take adequate measures to protect them.
On March 22, 2024, the Inter-American Court of Human Rights issued its judgment in the case. It found Peru responsible and ordered it to adopt comprehensive reparation measures. This decision is a historic opportunity to restore the rights of the victims, as well as an important precedent for the protection of the right to a healthy environment in Latin America and for adequate state oversight of corporate activities.
Background
La Oroya is a small city in Peru’s central mountain range, in the department of Junín, about 176 km from Lima. It has a population of around 30,000 inhabitants.
There, in 1922, the U.S. company Cerro de Pasco Cooper Corporation installed the La Oroya Metallurgical Complex to process ore concentrates with high levels of lead, copper, zinc, silver and gold, as well as other contaminants such as sulfur, cium and arsenic.
The complex was nationalized in 1974 and operated by the State until 1997, when it was acquired by the US Doe Run Company through its subsidiary Doe Run Peru. In 2009, due to the company's financial crisis, the complex's operations were suspended.
Decades of damage to public health
The Peruvian State - due to the lack of adequate control systems, constant supervision, imposition of sanctions and adoption of immediate actions - has allowed the metallurgical complex to generate very high levels of contamination for decades that have seriously affected the health of residents of La Oroya for generations.
Those living in La Oroya have a higher risk or propensity to develop cancer due to historical exposure to heavy metals. While the health effects of toxic contamination are not immediately noticeable, they may be irreversible or become evident over the long term, affecting the population at various levels. Moreover, the impacts have been differentiated —and even more severe— among children, women and the elderly.
Most of the affected people presented lead levels higher than those recommended by the World Health Organization and, in some cases, higher levels of arsenic and cium; in addition to stress, anxiety, skin disorders, gastric problems, chronic headaches and respiratory or cardiac problems, among others.
The search for justice
Over time, several actions were brought at the national and international levels to obtain oversight of the metallurgical complex and its impacts, as well as to obtain redress for the violation of the rights of affected people.
AIDA became involved with La Oroya in 1997 and, since then, we’ve employed various strategies to protect public health, the environment and the rights of its inhabitants.
In 2002, our publication La Oroya Cannot Wait helped to make La Oroya's situation visible internationally and demand remedial measures.
That same year, a group of residents of La Oroya filed an enforcement action against the Ministry of Health and the General Directorate of Environmental Health to protect their rights and those of the rest of the population.
In 2006, they obtained a partially favorable decision from the Constitutional Court that ordered protective measures. However, after more than 14 years, no measures were taken to implement the ruling and the highest court did not take action to enforce it.
Given the lack of effective responses at the national level, AIDA —together with an international coalition of organizations— took the case to the Inter-American Commission on Human Rights (IACHR) and in November 2005 requested measures to protect the right to life, personal integrity and health of the people affected. In 2006, we filed a complaint with the IACHR against the Peruvian State for the violation of the human rights of La Oroya residents.
In 2007, in response to the petition, the IACHR granted protection measures to 65 people from La Oroya and in 2016 extended them to another 15.
Current Situation
To date, the protection measures granted by the IACHR are still in effect. Although the State has issued some decisions to somewhat control the company and the levels of contamination in the area, these have not been effective in protecting the rights of the population or in urgently implementing the necessary actions in La Oroya.
Although the levels of lead and other heavy metals in the blood have decreased since the suspension of operations at the complex, this does not imply that the effects of the contamination have disappeared because the metals remain in other parts of the body and their impacts can appear over the years. The State has not carried out a comprehensive diagnosis and follow-up of the people who were highly exposed to heavy metals at La Oroya. There is also a lack of an epidemiological and blood study on children to show the current state of contamination of the population and its comparison with the studies carried out between 1999 and 2005.
The case before the Inter-American Court
As for the international complaint, in October 2021 —15 years after the process began— the IACHR adopted a decision on the merits of the case and submitted it to the Inter-American Court of Human Rights, after establishing the international responsibility of the Peruvian State in the violation of human rights of residents of La Oroya.
The Court heard the case at a public hearing in October 2022. More than a year later, on March 22, 2024, the international court issued its judgment. In its ruling, the first of its kind, it held Peru responsible for violating the rights of the residents of La Oroya and ordered the government to adopt comprehensive reparation measures, including environmental remediation, reduction and mitigation of polluting emissions, air quality monitoring, free and specialized medical care, compensation, and a resettlement plan for the affected people.

Lithium unveiled: Origins, extraction and environmental implications
One of the paradoxes of the energy transition is that it replaces the use of fossil fuels with mineral resources whose extraction and refining can have negative impacts on ecosystems, species and communities. This is happening with lithium, a mineral that has traditionally been used in glass and ceramics to provide greater adhesion and hardness, but is now being used primarily to make the batteries required by technologies that eliminate or reduce the use of fossil fuels. This has led to an increase in its demand. The serious social and environmental impacts of its extraction have been hidden or minimized. What makes lithium special? Lithium is a mineral in high demand due to its unique properties: It is the lightest metal with the highest electrochemical potential. It has a high energy storage capacity. It is malleable, so it can be adapted to different sizes, shapes and designs. These qualities make it a key material in the manufacture of batteries for cell phones, computers and, most importantly, electric vehicles. Lithium is considered key to the energy transition because it can be used to store non-conventional renewable energy, such as wind and photovoltaic power. Where it is: The so-called "lithium triangle"? The primary sources of lithium are salt flats, which are wetlands covered with a saline crust that contain brines, bodies of water in which many salts and elements, including lithium, are dissolved. Salt flats are attractive to the mining industry because of the relative technical ease of exploitation, low operating costs and low energy requirements to extract lithium from them compared to other sources. Worldwide, the salt flats of Argentina, Bolivia and Chile for 54 percent of lithium resources (potentially mineable material). In addition, Argentina and Chile hold 46 percent of the world's lithium reserves (the portion of known resources with a high level of confidence and proven economic viability). The mining industry has dubbed the region where the mineral is concentrated the "Lithium Triangle" - because that is all they see there - which includes northeastern Argentina, northern Chile and southern Bolivia. But there is much more than lithium in this region. There are also communities, ecosystems and species that depend on these salt flats. The region's inhabitants are engaged in small-scale ranching and subsistence agriculture, activities that require water, an already scarce resource in these latitudes. How is lithium mined from the salt flats? The procedure is as follows: The salt flat is drilled. The brine is poured into large pools or basins. Wait for the water to evaporate so that the lithium concentration increases. When the concentration is sufficient, the brine is sent to an industrial plant. The brine is chemically treated to produce lithium carbonate, which is marketed for battery production. Lithium extraction, especially by this method, involves huge consumption and loss of water because: Water is lost in pumping brine. Evaporation in ponds requires two million liters of water for every ton of lithium produced. Water is also needed in the final processes to obtain lithium carbonate and separate it from the rest of the compound. Lithium mining is threatening South America's salt flats, which are Andean wetlands, affecting local water availability and threatening the survival of communities and species living around these fragile ecosystems. The energy transition is urgent, but it must be equitable and not at the expense of other natural resource extraction that endangers people and the environment. sources -Maritza Tapia, “Claves del litio: el metal más liviano y con mayor potencial electroquímico”, Universidad de Chile. -Heinrich Böll Stiftung Colombia, “Litio: los costos sociales y ambientales de la transición energética global”. -Florencia Ballarino, “¿Qué es el litio, para qué sirve y de dónde se extrae en la Argentina?”, Chequeado. -Wetlands International, “El impacto de la minería de litio en los Humedales Altoandinos”. -Rodolfo Chisleanchi, “‘Triángulo de litio’: la amenaza a los salares de Bolivia, Chile y Argentina”, Mongabay Latam. -U.S. Geological Survey, Mineral Commodity Summaries, January 2023, “Lithium”.

5 years of the Kawésqar National Reserve: pending issues for its protection
Local communities denounce that the area is highly affected by salmon farming, which is failing to comply with environmental regulations.On January 30, 2019, the Official Gazette published the decree creating the Kawésqar National Reserve in Magallanes, which extends over 2,842 hectares between fjords and Patagonian peninsulas. The purpose of this classification was to guarantee the protection of the area, its territory and biodiversity, as well as to establish that it is the duty of the State to ensure its conservation. This year, 2024, marks the fifth anniversary of this milestone, which begs the question: is the reserve's objective being achieved"> Latin America is key to protecting biodiversity and combating the global climate crisis. Its forests, wetlands and marine ecosystems are among the most important carbon sinks on the planet, a service weakened by activities such as the exploitation and use of fossil fuels. At AIDA, we envision a region where the environment and communities, especially those in highly vulnerable situations, have lasting protections. To achieve this, we select precedent-setting cases that result in new, replicable tools and strategies that add to the protection of a healthy environment in the region. Having celebrated 25 years of working for the right to a healthy environment in the region, AIDA is poised to enter a new quarter century as a robust, multidisciplinary organization. In the coming years, we will continue and strengthen our pursuit of environmental and climate justice through two interconnected initiatives, each with defined lines of work: 1. Promotion of a just energy transition A just energy transition implies transforming the power relations between those who pollute the most and the rest of the world, avoiding the deepening of socio-environmental conflicts and protecting the rights of communities and people involved in energy generation processes. As this is an issue that cannot be addressed only at the national level, AIDA will contribute its regional vision to increase the scope of local and national decisions, enhance legal strategies, and strengthen a proposal for the continent’s transition. We will focus on: Avoiding dependence on oil and gas. Halting the extraction and use of coal. Promoting renewable and sustainable energies. Advocating for human rights-based climate finance and governance. 2. Protection of life-sustaining systems The ecosystem services that sustain life in Latin America and the world—including natural carbon capture and storage to mitigate the climate crisis, and the provision of clean food, air, and water - are at risk due to the lack of ambitious and effective actions. To ensure the livelihoods of life systems on the continent, both in rural communities and large cities, AIDA will focus its efforts on: Protecting the ocean, from the coasts to the high seas. Preserving freshwater sources and traditional territories. Defending culture and traditional livelihoods. Improving air quality. In the coming years, from our regional perspective, we will continue to contribute to solutions that center nature and communities, and that effectively address the continent’s social and environmental challenges.
