In the last decades the public concern on the pesticide residues content in foods have been steadily rising. The global development of food trade implies that aliments from everywhere in the world can reach the consumer`s table. Therefore, the identification of agricultural practices that employ different pesticides combinations and application rates to protect produce must be characterized, as they left residues that could be noxious to human health. However, the possible number of pesticides (and its metabolites of toxicological relevance) to be found in a specific commodity is almost 1500, and the time needed to analyze them one by one, makes this analytical strategy a unrealistic task. To overcome this problem, the concept of Multi Residue Methods (MRM) for the analysis of pesticide traces have been developed. The advent of new and highly sensitive instrumentation, based in hyphenatedchromatographic systems to coupled mass analyzers (XC (MS/MS) or MSn) permitted simultaneously the identification and the determination of up to hundreds of pesticide residues in a single chromatographic run. Multiresidue Methods for the Analysis of Pesticide Residues in Food presents the analytical procedures developed in the literature, as well as those currently employed in the most advanced laboratories that perform routinely Pesticide Residue Analysis in foods. In addition to these points, the regulations, guidelines and recommendations from the most important regulatory agencies of the world on the topic will be commented and contrasted.

Pesticide residue analysis is a specialized field of modern analytical chemistry, where the role of LC–MS is of great importance. A highly reliable determination, including both quantification and identification, of pesticide residues in food is required nowadays because of the strict international regulations on maximum residue Limits. The increasing interest of including metabolites in analyses comes from the inclusion of pesticide-related compounds within the residue definition. The polar character of most pesticides used at present and their metabolites make LC coupled to tandem MS the technique of choice for the great majority of compounds. Thus, LC–MS/MS with a triple-quadrupole (QqQ) analyzer is highly appropriate for developing multiresidue methods, where up to 200–300 analytes can be simultaneously determined. It can also be efficiently applied to solve analytical problems associated with some problematic pesticides, such as those present as ionic compounds in the samples, which have to be determined with more specific LC–MS/MS methods. High-resolution MS using modern analyzers like time of flight or Orbitrap offers interesting features for wide-scope screening of pesticides and metabolites in food, due to their mass accuracy capabilities, with the advantage that a retrospective analysis is feasible at any time to search for other compounds that were not included in the first analysis.

This book provides a critical overview of analytical methods used for the determination of pesticide residues and other contaminants in food and environmental samples by modern instrumental analysis. It contains up-to-date material including recent trends in sample preparation, general methods used for pesticide analysis and quality assurance aspects, and chromatographic and immunoassay methods. The rest of the book describes particular analytical methods used for the determination of pesticides in food and soil, water and air. In addition, the levels of these chemicals found in food, their regulatory aspects and the monitoring of pesticides in the environment are described.

Advances in analytical chemistry methodology now allow us to detect the most minute trace amounts of pesticides. As this capacity grows, so does public concern about toxic contamination, resulting in stricter government regulations and a growing demand for even more sensitive, precise, and reliable analysis. Addressing the interplay between regulations and the development of analytical technology, this volume presents the first unified treatment of the regulatory and analytical aspects of pesticide residues. Current regulations, existing and emerging methodologies, state-of-the-art instrumentation, and the basic science of analyzing for pesticides in food and other environmental media are all covered. The book provides step-by-step guidelines to analytical techniques, along with real-world examples from the latest research-showing the reader how to analyze minute traces of pesticides quickly and accurately, using both highly sophisticated and basic, less sensitive techniques. Many safety issues are explored in depth, as are the regulatory aspects of pesticide registration, residue analysis, exposure monitoring, risk assessment, and tolerance enforcement. Timely, authoritative, and practical throughout, Pesticide Residues in Foods is an invaluable reference for analytical chemists and laboratory managers everywhere-in industry, agriculture, environmental sciences, research, and instrument manufacturing-and for anyone with an interest in the broader environmental, agricultural, and consumer-related implications of pesticide use. An invaluable resource for analytical chemists and laboratory managers, Pesticide Residues in Foods provides a complete overview of the theory, practice, and regulatory aspects of pesticide residue analysis today, including: * All regulatory issues, from risk assessment and tolerance to data-quality requirements to laboratory accreditation standards * State-of-the-art methodologies and instrumentation, including high- performance liquid chromatography and mass spectrometry * The application of analytical technology to "green chemistry," such as the reduction of solvents and toxic reagents in the laboratory * Novel solutions to the old problem of keeping the food supply safe from harmful levels of pesticides * Ample examples to help analytical chemists select the most appropriate method for a given residue analysis * Easy-to-use tables and figures throughout the text
