"Mercury Contaminated Sites" is a specialized book that addresses the issue of mercury contamination in the environment. Mercury is one of the most significant global environmental pollutants and has increasingly attracted the attention of scientists, lawmakers, and the public over the past few decades. The book highlights the anthropogenic emissions that lead to increased mercury concentrations at local, regional, and global levels. It discusses the various industrial activities that have contributed to the contamination of soils and water bodies, as well as the associated risks to human and ecological health. Despite a significant decline in direct mercury emissions in the Western world over the last thirty years, other sources, such as coal combustion and the use of mercury in mining, remain globally significant. The book provides a comprehensive analysis of the impacts of mercury on various ecosystems and discusses the long-term challenges arising from this contamination.
