● Metals are increasingly important risk factors for the evolution of antibiotic resistance in environments. The rapid development of antibiotic resistance is occurring at a global scale. We therefore stride into the post-antibiotic era and have to battle antibiotic resistance in the Anthropocene. Metals are widely used and their pollution is widespread worldwide. More importantly, metal-induced co-selection greatly expands the environmental resistomes and increases the health risk of antibiotic resistance in environments. Here, we reviewed the metal-induced co-selection and their increasingly important roles in the development of antibiotic resistance. In particular, we highlight the metal-rich environments that maintain reservoirs for high-risk antibiotic resistance genes with horizontally transferable potentials. We also call for considerations and further investigations of other co-selective agents and the efficacy of metal-based interventions to better manage and combat the global antibiotic resistance crisis within the One Health framework.
