Reaction Mechanisms in Environmental Engineering: Analysis and Prediction describes the principles that govern chemical reactivity and demonstrates how these principles are used to yield more accurate predictions. The book will help users increase accuracy in analyzing and predicting the speed of pollutant conversion in engineered systems, such as water and wastewater treatment plants, or in natural systems, such as lakes and aquifers receiving industrial pollution. Using examples from air, water and soil, the book begins with a clear exposition of the properties of environmental and inorganic organic chemicals that is followed by partitioning and sorption processes and sorption and transformation processes. Kinetic principles are used to calculate or estimate the pollutants' half-lives, while physical-chemical properties of organic pollutants are used to estimate transformation mechanisms and rates. The book emphasizes how to develop an understanding of how physico-chemical and structural properties relate to transformations of organic pollutants.

Soil pollution receives less attention when compared to air pollution and water pollution. However, soil pollution is grabbing more attention nowadays. Undoubtedly, soil is an indispensable environmental matrix for the growth of any terrestrial plants. Nevertheless, the rapid growth rate of population expansion and urbanization exceeds the sustainability and recovery capability of the ecosystem. This has virtually resulted in soil pollution. The sources of soil pollution can come from various point and non-point sources. Of the obvious and commonest ones are domestic wastes, untreated or insufficient treatment of industrial discharges, husbandry wastes and agricultural uses of fertilizers, pesticides and herbicides. The purpose of this book is to provide the latest, if not the complete, updated information regarding the soil pollution from three main perspectives, namely, sources, health effects and management strategies in the agricultural and urban areas. The intended readers of this book include academicians, policy-makers, university students, teachers and researchers. This book contains eleven chapters. All chapters in this book consist of sources of pollutants (heavy metal monitoring) (Chapters One, Three, Six, Seven, Eight, Ten and Eleven), the application of the monitoring data for the human health risk assessment (Chapters One, Four, Five and Nine), and lastly, management strategies for the polluted soils (Chapters Two, Ten and Eleven). This book presents a thorough compilation of existing information on soil heavy metal pollution in the form of critical review papers (Chapters One, Two, Ten and Eleven) as well as original research papers (Chapters Three, Four, Five, Six, Seven, Eight and Nine). The invitation of prominent scientists from Japan such as Prof. Hideo Okamura (Kobe University, Japan), Prof. Hiroya Harino (Kobe College, Japan), Dr. Ye Feng and Dr. Muzembo Basilua Andre (both from the National Institute of Environmental Sciences, Tsukuba, Japan), Prof. Alireza Riyahi Bakhtiari (Tarbiat Modares University, Iran), and Dr. Salman Abdo Al-Shami (University of Tabuk, Saudi Arabia), who co-authored some of the chapters have helped to improve the quality of the chapters in this book. Additionally, chapters from Prof. Chen-Feng You from the National Cheng Kung University (Taiwan), Prof. Monica Butnariu from Banats University of Agricultural Sciences and Veterinary Medicine (Romania) and Dr. Nadi Awad Al-Harbi from Tabuk University (Saudi Arabia) are also important elements in the construction of international readership for this book.
