Environmental Chemistry: A Global Perspective

0.0

Environmental Chemistry: a global perspective describes those chemical principles which underpin the natural processes occurring within and between the air, water, and soil, and explores how human activities impact on these processes, giving rise to environmental issues of global concern. Guiding us through the chemical composition of the three key environmental systems - the atmosphere, hydrosphere, and terrestrial environment - the authors explain the chemical processes which occur within and between each system. Focusing on general principles, we are introduced to the essential chemical concepts which underpin an understanding of the air, water, and soil and how they behave; careful explanations ensure that clarity is not sacrificed at the expense of thorough coverage of the underlying chemistry. We then see how human activity continues to affect the chemical behaviour of these environmental systems, and what the consequences of these natural processes being disturbed can be. Environmental Chemistry: a global perspective takes chemistry out of the laboratory, and shows us its importance in the world around us. With illuminating examples from around the globe, its rich pedagogy, and broad, carefully structured coverage, this book is the perfect resource for any environmental chemistry student wishing to develop a thorough understanding of their subject. Key Features Emphasis is on general principles, which are illuminated with global examples Chemistry is covered at just the right depth for students to develop a thorough understanding of natural processes Carefully structured explanations ensure students from a variety of backgrounds can master the important chemical concepts In-text questions and end-of-chapter problems encourage students to check their understanding, and apply what they have learned to new scenarios and issues Online Resource Centre featuring: - Illustrations available to download - Solutions manual, containing solutions to problems presented in the book New to this Edition Increased emphasis on explanation, with additional descriptive material, to aid comprehension of the concepts being presented Enriched pedagogy, making the content more readily accessible to a broader range of students New 'route maps' for each chapter show the student what will be covered More detailed walk-throughs of calculations, to guide students and give more step-by-step support More worked examples, to build students' confidence in the material being presented New in-text questions to encourage students to check their understanding as they proceed through the book More frequent sub-headings, to aid navigation through chapters, and divide material into more manageable sections Annotated reading lists to encourage students to explore the primary literature Main points given throughout each chapter, highlighting the key concepts About The Author Gary W. vanLoon Department of Chemistry, Queen's University, Ontario, Canada Stephen J.
