Book Description
In 1929, Dr. W. H. Chapin and Mr. H. A. Burnett made a study of zinc ammonium phosphate and discovered the so-called 3,2 hydrated zinc ammonium phosphate, which has the formula (ZnNH4PO4)3 .2H2O. The salt was seen under microscope to consist of crystals in the form of separate needles and characteristic bundles radiating out from a center. It is an interesting and useful development of the study of the phosphates of zinc. Cadmium and zinc are in the same group of the periodic table and they have similar properties. It might be an interesting thing to follow the same procedure to get the cadmium ammonium phosphate. Very few people have studied the phosphates of zinc and probably still less have studied those of cadmium. It is desirable, therefore, to extend the chemical view along this line. There are also very few analytical methods for cadmium in use at the present time. It is the purpose, therefore, to find just what compounds are produced under varying analytical conditions, and to develop a dependable analytical method.

Book Description
Volume 11 provides in an authoritative and timely manner in 16 stimulating chapters, written by 40 internationally recognized experts from 11 nations, and supported by more than 2600 references, 35 tables, and over 100 illustrations, many in color, a most up-to-date view on the role of cadmium for life, presently a vibrant research area. MILS-11 covers the bioinorganic chemistry of Cd(II), its biogeochemistry, anthropogenic release into the environment, and speciation in the atmosphere, waters, soils, and sediments. The analytical tools for Cd determination, its imaging in cells, and the use of 113Cd NMR to probe Zn(II) and Ca(II) proteins are summarized, as are Cd(II) interactions with nucleotides, nucleic acids, amino acids, and proteins including metallothioneins. The phytoremediation by Cd(II)-accumulating plants, etc., the toxicology of Cd(II), its damage to mammalian organs, and its role as a carcinogen for humans, are highlighted.

Book Description
As the author states in his Preface, this book is written at a time when scientific and lay communities recognize that knowledge of environmental chemistry is fundamental in understanding and predicting the fate of pollutants in soils and waters, and in making sound decisions about remediation of contaminated soils. Environmental Soil Chemistry presents the fundamental concepts of soil science and applies them to environmentally significant reactions in soil. Clearly and concisely written for undergraduate and beginning graduate students of soil science, the book is likewise accessible to all students and professionals of environmental engineering and science. Chapters cover background information useful to students new to the discipline, including the chemistry of inorganic and organic soil components, soilacidity and salinity, and ion exchange and redox phenomena. However, discussion also extends to sorption/desorption, oxidation-reduction of metals and organic chemicals, rates of pollutant reactions as well as technologies for remediating contaminated soils. Supplementary reading lists, sample problems, and extensive tables and figures make this textbook accessible to readers. Provides students with both sound contemporary training in the basics of soil chemistry and applications to real-world environmental concerns Timely and comprehensive discussion of important concepts including: Sorption/desorption, Oxidation-reduction of metals and organics, Effects of acidic deposition and salinity on contaminant reactions Boxed sections focus on sample problems and explanations of key terms and parameters Extensive tables on elemental composition of soils, rocks and sediments, pesticide classes, inorganic minerals, and methods of decontaminating soils Clearly written for all students and professionals in environmental science and environmental engineering as well as soil science
