This book is divided into 10 chapters: the first is an introduction to the principles of chirality; Chapters 2 to 9 discuss the sources, distribution, biotransformation, toxicity, sample preparation and chiral resolution of environmental pollutants by chromatography and capillary electrophoresis. In addition, the optimization of experimental parameters for chromatographic and capillary electrophoretic techniques is presented, making this book a useful how to guide to chiral pollutants analysis. Coverage of the types, structures and properties of chiral stationary phases and their applications for the analysis of chiral pollutants is also presented. The concluding chapter reports on chiral legislation globally, and presents perspectives which could guide future research in this area.
This book will be of interest to researchers in biology, analytical chemistry and the environmental in industry, academia and governmental regulatory agencies.
