A new report from the Environmental Investigation Agency (EIA) reveals that mercury production is "out of control" in Mexico, the world's second largest producer, driven by high gold prices and cartel involvement. Despite the 2013 Minamata Convention, which aimed to restrict mercury production and use, illegal networks are smuggling the toxic element into South American countries like Colombia, Bolivia, and Peru, fueling illegal gold mining in the Amazon. The EIA tracked 200 tonnes of mercury from Mexico's Querétaro region, where at least 19 active mines operate without oversight, to the Amazon rainforest between 2019 and 2025.
The illegal mercury trade generates billions of dollars in illegal gold profits and has attracted the attention of Mexican cartels, such as the Jalisco New Generation cartel, which exerts control over some mines through armed presence and violence. The investigation resulted in the seizure of a five-tonne mercury shipment in Peru, the largest ever confiscated in an Amazonian country, highlighting the scale of the illegal operation. The mercury pollution contaminates rivers, soil, and air, causing severe environmental and social damage, especially affecting indigenous communities who experience increased health problems.
Illegal mining in the Amazon has increased by 50% between 2018 and 2024, causing a devastating impact on the region’s biodiversity. Mercury contamination poses serious health risks, particularly to children, leading to neurological disorders and developmental problems. The report calls for stricter enforcement of the Minamata Convention, increased international cooperation, and the use of technology to combat smuggling.
Impact Statement: The uncontrolled mercury trade in Latin America poses significant environmental and health risks, demanding urgent international collaboration and stricter regulatory enforcement to mitigate the devastating consequences.
