This book provides the traditional as well as modern analytical techniques used for sample preparation of different matrices for extraction, clean-up, detection and estimation of pesticide residues in soil, water and food commodities. It touches some aspects of most extraction cum clean-up techniques known as Quenchers methods. Brief history of pesticide development, modern pesticides and metabolic pathway of selected xenobiotics from different group of pesticides, imparts information on basic nature of pesticides. The book discusses latest analytical techniques like TLC, GLC, HPLC, HPTLC, super critical extraction and chromatography in simple but vivid manner. The sampling extraction, clean-up and solid phase extraction technique for residue analysis has been explained in the detail. Recently developed multi-residue methods have been outlined in a separate . Help from a number of standard reference books and research papers have given it a modern touch. Additionally a containing glossary of pesticide residue terms can be extremely helpful for a beginner in this fields. The book will provide students with sufficient background for the pesticides, their metabolism and above all various techniques for the estimation of residues of the toxic xenobiotics in all components of the environment. In short the book offers an excellent readable material for a knowledge seeker, may be a student or a research worker.
