Environmental Soil Chemistry

Environmental Soil Chemistry illustrates fundamental principles of soil chemistry with respect to environmental reactions between soils and other natural materials and heavy metals, pesticides, industrial contaminants, acid rain, and salts. Timely and comprehensive discussions of applications to real-world environmental concerns are a central focus of this established text.

Provides students with both sound contemporary training in the basics of soil chemistry and applications to real-world environmental concernsTimely and comprehensive discussion of important concepts including: sorption/desorption, oxidation-reduction of metals and organics, and effects of acidic deposition and salinity on contaminant reacionsBoxed sections focus on sample problems and explanations of key terms and parametersExtensive tables on elemental composition of soils, rocks and sediments, pesticide classes, inorganic minerals, and methods of decontaminating soilsClearly written for all students and professionals in environmental science and environmental engineering as well as soil science
