This collection of up-to-date methods for analyzing pesticide residues represents those proven methods that are of most value to the analyst. The methods chosen demonstrate a particularly high standard of reliability and have all been validated by at least one other specially qualified laboratory. They are also presented in such detailed and readily understandable form that analysts using them cannot possibly be left in doubt about how to proceed. Each of the single methods specifies the substrates to which it is suited and on which it has been validated, among them food crops, stored commodities, processed food of vegetable and animal origin, feedstuffs, forage and fodder crops, soil, and water. Both Volumes arrange the compound-specific methods in the alphabetical order of the compound names. They also contain indexes to provide quick access to the desired method. The single methods each contain the chemical name and the structural formula of the respective compound. Multiple methods are preceded by a table in which chemical names and structural formulae are presented jointly for all compounds.

Determination of Multiple Pesticides Residues in Imported Tea in UAE Using Liquid and Gas Chromatography and Tandem Mass Spectrometry Excerpt :

An accurate, rapid and reliable method for the simultaneous determination of 48 pesticide residues in United Arab Emirates imported tea (Green and Black) by liquid and gas chromatography coupled with tandem mass spectrometry LC-ESI (+) - MS/MS and GC-EI-MS/MS. Multiple reaction monitoring (MRM) mode was used in which two transitions for each compound for pesticide identification and quantification in the presence of internal standards. Modified quick, easy, cheap, effective, rugged, safe (QuEChERS) method was used for sample clean up and preparation for chromatographic analysis. The performance of the newly developed analytical method was validated in accordance with EU SANCO guidelines (SANCO/12571/2013) for monitoring pesticide multi-residues by evaluating method linearity, recoveries, precision (reproducibility and repeatability), sensitivity (limits of detection (LODs) and limits of quantification (LOQs)) for each one of the tested pesticides. LC-MS/MS was used to detect and quantitate 38 pesticides residues. For Black tea, 70% of tested pesticides spiked at levels of 10 and 100 ng.mL-1, the mean recoveries were 99.83% and 94.27%, and average RSD were 14.38% and 13.4 %, respectively. For Green tea, 80% of the tested pesticides spiked at levels of 10 and 100 ng mL-1, the mean recoveries were 93.75% and 95.08, and average RSD was 11.10% and 13.14%, respectively. GCMSMS, used to detect 10 pesticides residues. For Black tea, 70% of tested pesticides spiked at levels of 10 and 100 ng mL-1, the mean recoveries were 85.35% and 78.47%, and average RSD were 10.50% and 8.60%, respectively. For Green tea, 80% of the tested pesticides spiked at levels of 10 and 100 ng mL-1, the mean recoveries were 79.29% and 73.35%, and average RSD were 7.46% and 5.94%, respectively. The limits of detection for all targeted pesticides lower than the respective MRL established by codex and the EU legislations. Real tea samples of different types and brands were collected from UAE local mark

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.

Analysis of Chemical Contaminants in Food Excerpt :

How many times have we thought with concern about the possible contamination of food? Pollution, agricultural treatments, technological treatments, and packaging are the best-known human sources of toxic substances as food contaminants. The present book contains 11 original research papers representing various approaches of identifying and measuring toxic residues in food materials. The analytical determination of food contaminants is an indispensable tool in characterizing the adverse effects and unexpected toxicity related to food intake. No risk assessment would be possible without data from the analysis of food contaminants. This Special Issue is an interesting overview of recent methods and is highly representative of a broad worldwide outline, collecting authors from ten different countries and four continents. Very different toxics are described, from volatile organic compounds to heavy metals and from highly polar chemicals to classical organic contaminants. A wide range of analytical techniques are portrayed, including sample preparation and clean-up methodologies, classical chromatographic and hyphenated spectroscopies, and the latest high-resolution mass spectrometry applications. The presented works consider a varied selection of foods: the studied matrices are meat, fishery products, fruits, and miscellaneous beverages.

Soil Heavy Metals Excerpt :

Human activities have dramatically changed the composition and organisation of soils. Industrial and urban wastes, agricultural application and also mining activities resulted in an increased concentration of heavy metals in soils. How plants and soil microorganisms cope with this situation and the sophisticated techniques developed for survival in contaminated soils is discussed in this volume. The topics presented include: the general role of heavy metals in biological soil systems; the relation of inorganic and organic pollutions; heavy metal, salt tolerance and combined effects with salinity; effects on abuscular mycorrhizal and on saprophytic soil fungi; heavy metal resistance by streptomycetes; trace element determination of environmental samples; the use of microbiological communities as indicators; phytostabilization of lead polluted sites by native plants; effects of soil earthworms on removal of heavy metals and the remediation of heavy metal contaminated tropical land.
