This book, "Heavy Metals in Soils: Trace Metals and Metalloids in Soils and their Bioavailability," is the third edition of a comprehensive reference on heavy metals and metalloids in soils. It covers the general principles of their occurrence, chemical behavior, and interactions with soil organisms, plants, and animals, along with detailed information on 21 individual elements. The book is edited by Brian J. Alloway and includes contributions from various experts in environmental science, soil science, geochemistry, and related fields. The book is structured into three main parts. Part I covers basic principles, including toxicity in soil organisms, soil-plant relationships, heavy metals as micronutrients, and modeling of critical loads. Part II focuses on key heavy metals and metalloids, including arsenic, cadmium, chromium, cobalt, copper, lead, mercury, nickel, selenium, and zinc. Part III expands on other heavy metals and metalloids of environmental significance, such as antimony, barium, gold, molybdenum, silver, thallium, tin, tungsten, uranium, and vanadium. The book provides an in-depth understanding of the occurrence, availability, and environmental impact of heavy metals and metalloids in soils. It is a valuable resource for advanced undergraduate and postgraduate students, research scientists, and professionals in environmental science, soil science, geochemistry, agronomy, environmental health, and land management. The book also includes a glossary of specialized terms and an index for easy reference.This book, "Heavy Metals in Soils: Trace Metals and Metalloids in Soils and their Bioavailability," is the third edition of a comprehensive reference on heavy metals and metalloids in soils.
