Advancing environmental health research in the era of global change

The growing threats faced by toxic metals in the environment are directly linked to industrialization, urbanization, and climate change. These processes have intensified the global distribution of pollutants such as cadmium, lead, and mercury, creating significant public health risks. Toxic metals now infiltrate ecosystems through various pathways, including air, water, and soil, contributing to both immediate and long-term health effects. The role of cadmium in inducing oxidative stress, DNA damage, and cancer, particularly among vulnerable communities living in industrial zones has been established. Similarly, lead exposure has been linked to neurotoxicity, impaired cognitive function, and increased cancer risk. Studies on metal homeostasis using model organisms, such as yeast, have advanced our understanding of how cells respond to toxic exposure and given rise to practical solutions through biotechnological interventions. Sustainable remediation strategies that incorporate green chemistry, phytoremediation, and circular economy principles are essential to address environmental contamination. The development of stronger regulatory frameworks is critical to reducing toxic metal exposure and promoting public health. Addressing these issues requires a cross-disciplinary collaboration between molecular biologists, environmental scientists, public health experts, and policymakers. This review highlights the future of environmental health research, and its focus on creating lasting, preventive solutions that not only mitigate current contamination but also reduce the risk of future environmental toxins.
