Environmental Soil Physics

A broad range of topics are covered: the role of mineral colloids in carbon turnover and sequestration and the impact on climate change, biogeochemical interfacial reactions and dynamics of vital and toxic elements, ecotoxicology of anthropogenic organics, environmental nanoparticles and their impacts, and ecosystem health.

Incorporating fundamental principles as well as up-to-date applications in soil formation, this work emphasizes the equal importance of organic and inorganic soil constituents by delineating the role of complex carbohydrates, amino acids, proteins, lipids, nucleic acids, lignins, enzymes, and humic acids in soil reactions. This edition features coverage of the relation of pe-pH with the biochemical cycle, soil air quality and soil humidity, thermodynamics in cation exchange and its connection with the quantity ntensity ratio, and more.

The study of environmental physics requires understanding topics from many di?erent areas of physics as well as comprehension of phy- cal aspects of the world around us. Several excellent textbooks are available covering most aspects of environmental physics and of appli- tions of physics to the natural environment from various points of view. However, while teaching environmental physics to university students, I sorelymissedabookspeci?callydevotedtoexercisesfortheenvironm- tal science student. Thus, the motivation for this book came about as in physics, as well as in many other disciplines, satisfactory knowledge of a subject cannot be acquired without practice. Usually students are not familiar with the various areas of physics that are required to describe both the environment and the human impact upon it. At the same time, students need to develop skills in the manipulation of the ideas and c- cepts learned in class. Therefore, this exercise book is addressed to all levels of university students in environmental sciences. Because of the wide range of potential users this book contains both calculus-based and algebra-based problems ranging from very simple to advanced ones. Multiple solutions at di?erent levels are presented for certainproblems—thestudentwhoisjustbeginningtolearncalculuswill bene?t from the comparison of the di?erent methods of solution. The material is also useful for courses in atmospheric physics, environmental aspects of energy generation and transport, groundwater hydrology, soil physics,andoceanphysics,andselectedpartsmayevenbeusedforbasic undergraduate physics courses. This collection of exercises is based on courses taught at the University of Northern British Columbia and at the University of Victoria, Canada.
