A Mexican recycling plant processing hazardous waste from the US was temporarily shut down following an investigation exposing heavy metal contamination in nearby areas. The investigation by the Guardian and Quinto Elemento Lab found high levels of toxins such as lead in local schools and homes, with one school exceeding US lead dust limits by a significant margin. The federal environmental agency, Profepa, announced the closure to inspect the plant's compliance, citing unauthorized emissions equipment. Local and federal agencies observed deficiencies in emission controls, prompting further actions. Residents and activists in Monterrey are mobilizing against the pollution, demanding transparency and stricter regulations to protect community health.
