Metal Toxicity and Human Health: Sources, Exposure Routes, and Preventive Strategies

Environmental pollution from industrial, agricultural, and nutritional sources causes metal poisoning, which is a serious health risk to humans. With an emphasis on their effects on biological systems, this overview examines the several ways that metals may enter the body, such as through the air, water, soil, and food. While hazardous metals like lead, mercury, arsenic, and cadmium disturb cellular homeostasis and result in oxidative stress, neurotoxicity, and organ destruction, essential metals like copper and zinc are essential for physiological processes. Contamination of packaged food and water increases exposure risks and can result in long-term health issues like cancer, heart disease, and developmental abnormalities. Developing preventative measures requires an understanding of the processes behind metal toxicity, such as bioaccumulation, enzyme inhibition, and DNA damage. In order to mitigate metal pollution, this chapter emphasizes the importance of industrial waste management, regulatory frameworks, and bioremediation strategies. To lessen human exposure, better packing materials and environmentally friendly farming methods are also advised. To protect the public from the harmful consequences of metal toxicity, a thorough, interdisciplinary strategy that combines technical innovation, regulatory enforcement, and public awareness is necessary.
