Xenobiotics are chemical compounds foreign to a given biological system. In animals and humans, xenobiotics include drugs, drug metabolites, and environmental pollutants. In the environment, xenobiotics include synthetic pesticides, herbicides, and industrial pollutants. Many techniques are used in xenobiotics residue analysis; the method selected depends on the complexity of the sample, the nature of the matrix/analytes, and the analytical techniques available. This reference will help the analyst develop effective and validated analytical strategies for the analysis of hundreds of different xenobiotics on hundreds of different sample types, quickly, accurately and at acceptable cost.

This volume offers the latest theory, procedures, techniques and applications pertaining to the bioremediation of pesticides, as well as current case studies. The book is composed of chapters written by global experts and is divided into three topical sections. Section A deals with concepts and mechanisms of pesticides bioremediation; Section B examines latest tools and techniques; Section C offers global case studies of pesticides bioremediation. The novel methods described here are timely, as traditional pesticide usage leads to high wastage via decay, vaporization and seepage. This of course leads to environmental contamination and has necessitated the development and use of novel technologies like bioremediation for minimizing the impact of pesticides on the environment. This volume will be of relevance to academics, researchers and students who are working in the realm of pesticide bioremediation, and will enable policy makers and managerial experts across the globe in drafting policies and strategies for the management and treatment of pesticides.

Analytical Methods for Agricultural Contaminants provides proven laboratory practices and methods necessary to control contaminants and residues in food and water. This reference provides insight into good laboratory practices and examples of methods used in individual specialist laboratories, thus enabling stakeholders in the agri-food industry to appreciate the importance of proven, reliable data and the associated quality assurance approaches for end product testing for toxic levels of contaminants and contaminant residues in food. The book offers standard operating procedures and tools for researchers, practitioners and students to confidently engage in using research methods with the aim to control contaminants. Users in a laboratory setting will find this to be a practical and useful reference on how to detect and control agricultural contaminants for a safe food supply. - Provides coverage of risk assessment and effective testing technologies - Presents the most up-to-date information in research sample preparation and method validation to detect chemical residues - Includes examples of each method for practical application - Demonstrates proven, reliable research data and the associated quality assurance approaches for end product testing

The purpose of this second edition is to bring together the current rapid developments and activities in residues of veterinary drugs within the European Community. The EEC legislation is summarised. There is information on the Reference Laboratories, the Maximum Residues Limits (MRL) and the criteria for the methods to be used for routine analysis of residues by Member States and third countries wishing to export meat to the EC. The current state of examination of residues practised and the analytical methods used in Member States is described in detail. There is a section on quality assurance in the laboratory and also supporting information on residues and chemical/physical data of the most important veterinary drugs

Time of flight mass spectrometry identifies the elements of a compound by subjecting a sample of ions to a strong electrical field. Illuminating emerging analytical techniques in high-resolution mass spectrometry, Liquid Chromatography Time-of-Flight Mass Spectrometry shows readers how to analyze unknown and emerging contaminants—such as antibiotics, steroids, analgesics—using advanced mass spectrometry techniques. The text combines theoretical discussion with concrete examples, making it suitable for analytical chemists, environmental chemists, organic chemists, medicinal chemists, university research chemists, and graduate and post-doctorate students.

Planar Chromatography-Mass Spectrometry focuses on a relatively new approach to chemical analysis in general, and to separation science in particular. It is the first book to systemically cover the theoretical background, techniques, instrumentation, and practical applications of planar chromatography-mass spectrometry as a hyphenated tool of analy
