Cadmium is a heavy metal with proven toxic effects, omnipresent in various sectors such as industry and agriculture. Its toxicity manifests itself principally through damage to the kidneys, liver and immune system, and it can also interfere with essential metals such as zinc, aggravating its harmful effects. Cadmium contamination poses serious environmental challenges, affecting biodiversity and ecosystem health through bioaccumulation in the food chain. Faced with these challenges, it is crucial to implement prevention strategies, such as strict regulations, sustainable agricultural practices and awareness-raising campaigns. Decontamination of polluted sites must also be a priority, using methods such as phytoremediation and soil stabilization. The mobilization of everyone, from governments to citizens, is essential to reduce cadmium exposure and ensure a safer, healthier future for all.
