This book was released on 1996 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study investigated the pesticide cross-contamination that occurs during laundering. The effects of pesticide, water temperature, and fabric combination were examined. Pesticide soiled fabric samples were individually laundered along with the same weight fabric that had not been exposed to pesticides in an Atlas Launder-Ometer in a method to represent one home laundry cycle. Samples were individually extracted and analyzed using gas Chromatographie techniques. An analysis of variance procedure was used to test for the main effects and interactions of the main effects. All main effects were significant at the 0.01 level. Further examination of all possible pair-wise comparisons of treatment means was carried out with a Duncan's multiple range post hoc procedure. Cross-contamination of pesticide residue was found to be dependent on pesticide with individual pesticides exhibiting different patterns of residue transfer. Laundry conditions and fabrics that allow for greater removal of pesticide residue provided an opportunity for more pesticide to be transferred to other fabrics.

This book was released on 2000 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: Workers using pesticide are required by federal law to wear personal protective equipment. Thus, understanding the interaction between pesticide and the surface of protective clothing fabrics is necessary to facilitate design of fabrics that meet federal regulations and are cost-effective and comfortable to wear. Six protective clothing fabrics, two woven and four nonwoven, were investigated to determine distribution patterns of pesticide residues on the fabrics. We developed procedures to measure and describe image characteristics of these protective clothing fabrics in their natural state and related those to images with pesticide contamination. Pesticide distribution patterns were different depending on the fabric structure and fiber content. Mainly, pesticide residues crystallized on fiber surfaces except for the 100% cotton woven fabric, in which pesticide was believed to be absorbed into the cotton fibers and thus less amounts of pesticide were shown on the surface. The 100% polyethylene fabric was sheet-like, so pesticide residues spread evenly on the fabric surface. Image analysis of fabric structure with or without pesticide contamination revealed that images darkened with the addition of pesticide; however, images with pesticide contamination darkened differently between the six protective clothing fabrics.

This book was released on 2017-10-10 with total page 531 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Worldwide concern in scientific, industrial, and governmental com munities over traces of toxic chemicals in foodstuffs and in both abiotic and biotic environments has justified the present triumvirate of specialized publications in this field: comprehensive reviews, rapidly published progress reports, and archival documentations. These three publications are integrated and scheduled to provide in international communication the coherency essential for nonduplicative and current progress in a field as dynamic and complex as environmental contamination and toxicology. Until now there has been no journal or other publication series reserved exclusively for the diversified literature on "toxic" chemicals in our foods, our feeds, our geographical surroundings, our domestic animals, our wild life, and ourselves. Around the world immense efforts and many talents have been mobilized to technical and other evaluations of natures, locales, magnitudes, fates, and toxicology of the persisting residues of these chemicals loosed upon the world. Among the sequelae of this broad new emphasis has been an inescapable need for an articulated set of authorita tive publications where one could expect to find the latest important world literature produced by this emerging area of science together with documentation of pertinent ancillary legislation.
