Description
This book explores the concept of heavy metals, their definition, environmental significance, and the toxicological risks they pose to humans and ecosystems. It delves into the distinction between essential trace elements and harmful metals like lead, mercury, and cadmium, examining their sources, biological roles, and harmful effects. From their occurrence in nature to their concentration due to human activities, the book highlights how these metals accumulate in living organisms, leading to health issues and ecological imbalance. It also covers the methods of treating heavy metal poisoning and discusses the dual nature of metals—essential in trace amounts but toxic in excess.
