This book takes an in-depth look at copper (Cu) and zinc (Zn) imbalances, as well as metal poisoning, with a particular focus on mercury. Highlighting sources of contamination, health effects, mechanisms of toxicity and detoxification strategies, it offers a holistic understanding of these crucial issues. Emphasizing the importance of ongoing research, it calls for a multidisciplinary approach to better understand the interactions between metals in the human body, and to develop more effective prevention and treatment measures. This book thus provides an essential resource for health professionals, researchers and policy-makers involved in protecting public health from the dangers of heavy metals.
