One of the two enantiomers of a chiral pollutant may be more toxic than the other, and about 25 % of agrochemicals are chiral in nature – including pesticides, which are applied in agricultural and forestry activities in the form of their racemates. The biological transformation of chiral pollutants can be stereoselective, such that the uptake, metabolism and excretion of the enantiomers may be very different.

Therefore, the enantiomeric composition of chiral pollutants may be changed during these processes. The metabolites of chiral compounds are often chiral. Therefore, to predict the exact toxicities of pollutants, determination of the concentrations of both enantiomers is essential, and hence environmental scientists are eagerly seeking techniques for their analysis. Moreover, diverse groups of people – ranging from regulators to the materials industries, clinicians and nutritional experts, agriculturalists and environmentalists – are also now demanding data on the ratio of pollutant enantiomers, rather than their total concentrations.

Various approaches to chiral resolution have been developed for the analysis of pharmaceuticals and drugs but, unfortunately, few reports and monographs are available on the chiral separation of pollutants. Therefore, we have set out to write this book, which deals with the distribution, toxicities and art of analysis of chiral pollutants by gas chromatography and liquid chromatography; that is, by high performance liquid chromatography (HPLC), sub- and supercritical fluid chromatography (SFC), capillary electrochromatography (CEC) and thin layer chromatography (TLC).

Additionally, a chapter has been included on the chiral analysis of pollutants by capillary electrophoresis. This book also describes the types, structures and properties of chiral stationary phases, and the applications and future scope of chiral resolution. Moreover, we have attempted to explain the optimization of chiral analysis, which will be helpful in the design of future experiments in this area. Attempts have also been made to explain chiral recognition mechanisms in detail. We very much hope that this book will be a useful source of information for scientists, researchers, academics and graduate students who are working in the field of the chiral analysis of pollutants.
