Heavy metals can be emitted into environment by both natural and anthropogenic sources, mainly mining and industrial activity. Human exposure occurs through all environmental media. Infants are more susceptible to the adverse effects of exposure. Increasing attention is now being paid to the mental development of children exposed to heavy metals. The purpose of this book is to evaluate the existing knowledge on intellectual impairment in children exposed to heavy metals in their living environment and to identify the research needs in order to obtain a clearer picture of the situation in countries and regions at risk, in which the economy is closely related to metallurgy and heavy metals emission, and to recommend a strategy for human protection. In greater detail the main objectives could be formulated as follows: to review the principal sources of single, and complex mixtures of, heavy metal pollutants in the environment; to identify suitable methodology for chemical analyses in the environment and in humans; to evaluate the existing methods for measuring mental impairment, including their reliability and validity; to recommend a standard testing protocol to be used in future research; to assess the future role of environmental heavy metal pollution in countries and regions at risk and its effects on children's neurological development; to recommend a prevention strategy for protecting children's health and development.

Atmospheric aerosols are an important and a highly complex component of the Earth's atmosphere that alter the radiative forcing and the chemical composition of the gas phase. These effects have impacts on local air quality and the global climate. Atmospheric Aerosol Chemistry outlines research fi ndings to date in aerosol chemistry and advances in analytical tools used in laboratory settings for studying their surface and bulk reactivity.

This book explains the correct logical approach to analysis of forensic scientific evidence. The focus is on general methods of analysis applicable to all forms of evidence. It starts by explaining the general principles and then applies them to issues in DNA and other important forms of scientific evidence as examples. Like the first edition, the book analyses real legal cases and judgments rather than hypothetical examples and shows how the problems perceived in those cases would have been solved by a correct logical approach. The book is written to be understood both by forensic scientists preparing their evidence and by lawyers and judges who have to deal with it. The analysis is tied back both to basic scientific principles and to the principles of the law of evidence. This book will also be essential reading for law students taking evidence or forensic science papers and science students studying the application of their scientific specialisation to forensic questions.

Concepts & Calculations in Analytical Chemistry: A Spreadsheet Approach offers a novel approach to learning the fundamentals of chemical equilibria using the flexibility and power of a spreadsheet program. Through a conceptual presentation of chemical principles, this text will allow the reader to produce and digest large assemblies of numerical data/calculations while still focusing on the chemistry. The chapters are arranged in a logical sequence, identifying almost every equilibrium scenario that an analytical chemist is likely to encounter. The spreadsheet calculations and graphics offer an excellent solution to otherwise time-consuming operations. Worked examples are included throughout the book, and student-tested problems are featured at the end of each chapter. Spreadsheet commands for QuattroPro, Quattro, and Lotus 1-2-3 are embedded in the text.
Concepts & Calculations in Analytical Chemistry: A Spreadsheet Approach has been designed to serve both as a supplement to an undergraduate quantitative analysis course or as a text in a graduate-level advanced analytical chemistry course. Professional chemists will also find this to be an excellent introduction to spreadsheet applications in the lab and a modern overview of analytical chemistry in a self-study format.

The use of silicon-based microsystems for chemical analysis is one of the most promising concepts in the recent developments in micro system technology (MST). It is expected that chemical sensors will be increasingly integrated in so-called miniaturized total analysis systems (uTAS), a concept first presented by Ciba-Geigy. In such systems, all steps in a chemical determination, from sampling to detection and data treatment, are integrated in one miniature instrument. uTAS offer a variety of advantages over conventional analysis systems such as improved analytical performance, reduced reagent and power consumption, small size, possibility of new and more complicated functions, higher reliability and lower fabrication costs. Application of uTAS may be found in fields like process industry, environmental monitoring, medical diagnostics, aeronautics, automotive industry, and more.
