The book provides information on the sources of arsenic contamination of groundwater and their impacts in the first part of the book consisting of 8 chapters. Process developments such as nano-adsorbents for removal of arsenic and other heavy metals are discussed in the second part of the book that comprises of 4 chapters. The third part of the book includes 4 chapters on technological interventions for the removal of arsenic such as indigenous ceramic membranes and Subterranean Arsenic Removal (SAR). The fourth part of the book deals with arsenic contamination in food materials and food chain systems, and consists of 5 chapters. Arsenic has long been associated with a variety of health complications in the human body. In order to address this, a chapter on arsenic contamination and impacts on human health has been included in the fifth part of the book. The book would be a valuable reference material for the scientific community in developing countries working on community water supply and treatment, food safety, public health and policy.

The important role of?nely dispersed matter and surfaces in medicine is not always fully understood and appreciated. Speci?cally,?ne particles (solid or liquid) in the size range of several nanometers to several micrometers have a tremendous effect on our lives, because they can be bene?cial or detrimental to our well-being. Such particles are present in living bodies as red blood cells or cholesterol crystals in the gall bladder. They are ubiquitous in the environment, where they can cause many diseases, such as asbestosis, silicosis, and black lung disease, but they are also used in diagnostic tests, drug delivery, and numerous other applications. More recently, evidence has become available that drug formulations with active components in a?nely dispersed state may signi?cantly affect their functionality. Furthermore, with miniaturization of medical instrumentation, the size of the components is necess- ily reduced to colloid or even smaller range. This volume is a collection of several chapters dealing with diverse topics of colloids and surfaces relevant to medical applications. Thus, Siiman describes the use of optical properties of uniform colloidal particles as probes in?ow cytometry. Giesche focuses on the preparations and properties of exceedingly uniform silica spheres for different uses, such as in chromatography. In modi?ed forms, silica p- ticles with incorporated dyes are employed in diagnostics and those combined with tiny magnetic entities in drug delivery.
