Environmental pollution by man-made persistent organic chemicals (POCs) has been a serious global issue for over half a century. POCs are prevalent in air, water, soil, and organisms including wildlife and humans throughout the world. They do not degrade and cause long-term effect in organisms. Exposure to certain POCs may result in serious environ

TRAC: Trends in Analytical Chemistry, Volume 11 presents relevant topics in global analytical chemistry research. This book discusses the fundamental principle of competitive immunoassays. Organized into 27 chapters, this volume begins with an overview of the general and important contributions relating to the presentation of forensic evidence to courts of law. This text then discusses the importance of the analysis of scanned measuring quantities. Other chapters consider the advantages as well as the drawbacks of coupled chromatographic methods. This book discusses as well the status of analytical chemistry within the broader scientific arena as a practical rather than fundamentally oriented discipline. The final chapter deals with the properly functioning process control system in manufacturing insulin by reversed-phase high-performance liquid chromatography (RP–HPLC). This book is a valuable resource for analytical, organic, clinical, and regulatory chemists. Electrochemists, scientists, students, engineers, researcher workers, and other practitioners will also find this book extremely useful.

Trends in Analytical Chemistry, Volume 12 focuses on the advancements of processes, technologies, automation, and applications of analytical chemistry. The selection first offers information on single-cell analysis at the level of a single human erythrocyte and micellar catalysis in reaction-rate methods. Topics include analytical strategies, analysis of single erythrocytes, kinetic aspects of micellar catalysis, and micellar kinetic multicomponent determination. The text then takes a look at advances in the field of laser atomic spectroscopy and molecular recognition of sugars, including detection of sugar complexation, driving force and selectivity of sugar complexation, atomization/excitation source, and diagnostic tool. The manuscript examines charge-remote fragmentations for structural determination of lipids; advances in speciation analysis by capillary gas chromatography; and chemical pattern recognition and multivariate analysis for QSAR studies. The publication also ponders on in-vivo microdialysis sampling in pharmacokinetic studies; a novel single beam optical spectrophotometer for fast luminescence, absorption, and reflection measurements of turbid materials; and techniques for the study and characterization of advanced materials. The selection is a dependable reference for readers interested in the trends in analytical chemistry.

This volume is a review of the trends in the field of radiation chemistry research. It covers a broad spectrum of topics, ranging from the historical perspective, instrumentation of accelerators in the nanosecond to femtosecond region, through the use of radiation chemical methods in the study of antioxidants and nanomaterials, radiation-induced DNA damage by ionizing radiation involving both direct and indirect effects, to ultrafast events in free electron transfer, radiation-induced processes at solid-liquid interfaces and the recent work on infrared spectroscopy and radiation chemistry. The book is unique in that it covers a wide spectrum of topics that will be of great interest to beginners as well as experts. Recent data on ultrafast phenomena from the recently established world-class laser-driven accelerators facilities in the US, France and Japan are reviewed.

Trends in Analytical Chemistry, Volume 3 focuses on developments in analytical chemistry, including the adoption of automation in laboratory processes, chromatography, and flow analysis. The selection first underscores the effect of automation on the operations of analytical laboratories and techniques for the automated optimization of HPLC separations. Topics include initial requirements, window diagrams, and chemometric approaches. The text then ponders on generation of statistical tables by microcomputer; enzyme electrodes for continuous in-vivo monitoring; and enantiomeric analysis of the common protein amino acids by liquid chromatography. The publication takes a look at sample preparation for the analysis of heavy metals in foods and application of ion-selective electrodes in flow analysis, including dry ashing, acid extraction, and ion-selective electrodes in flowing systems. The text then examines trends in laboratory information management systems; zone electrophoresis in open-tubular capillaries; and using computers to interpret IR spectra of complex molecules. The selection is a valuable source of data for readers interested in the developments in analytical chemistry.
