Book excerpt: Knowledge of the concentration of the contaminants and the molecular state of their degradation products is helpful in assessing the environmental risks associated with the contaminants as well as evaluating the design of remediation technologies. A great deal of interest has been generated recently in the determination of explosives and explosives' by-products in plant tissues. The methods traditionally used for the analysis of explosives in solid matrixes are not adequate due to the high organic content of the plant tissues. Data that are obtained using analytical methods not designed for the specific matrix encountered may lead to incorrect quantitation of the target analyte. The methods used to detect the explosives and their degradation products require matrix-specific sample preparation, separation by reversed phase high performance liquid chromatography, and ultraviolet detection. This report addresses three important points in connection with the analysis of explosives in plant tissues: extraction, interferences, and method performance. The extraction of the contaminants from the matrix requires a different set of extraction techniques from those used for standard water and soil extractions. These exotic matrixes contain much higher organic content than soil or water and, as a result, are prone to interference from biological molecules. A liquid chromatographic cleanup step is utilized to reduce these interferences. The performance of the modified method is reported with respect to method detection limits, analyte percent recoveries, and the methods applicability for analysis of contaminated plant tissues from plant uptake studies.

Download or read book Sampling and Sample Preparation in Field and Laboratory written by Janusz Pawliszyn and published by Elsevier. This book was released on 2002-09-09 with total page 1170 pages. Available in PDF, EPUB and Kindle. Book excerpt: This title is the first comprehensive book on sampling and modern sample preparation techniques and has several main objectives: to facilitate recognition of sample preparation as both an integral part of the analytical process; to present a fundamental basis and unified theoretical approach for the professional development of sample preparation; to emphasize new developments in sample preparation technology; and to highlight the future impact of sample preparation on new directions in analytical science, particularly automation, miniaturization and field implementation. Until recently, there has been relatively little scientific interest in sampling and sample preparation, however this situation is presently changing as sampling and sample preparation become integral parts of the analytical process with their own unique challenges and research opportunities. Sampling and Sample Preparation for Field and Laboratory is an essential resource for all analytical chemists, and in particular those involved in method development. Not only does it cover the fundamental aspects of extraction, it also covers applications in various matrices and includes sampling strategies and equipment and how these can be integrated into the analytical process for maximum efficiency.

This book was released on 2019-01-30 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ambient mass spectrometry—that is the use of mass spec but in the atmospheric environment—has been widely employed in food and environmental analysis. Ambient Mass Spectroscopy Techniques in Food and the Environment presents the theoretical underpinnings of mass spectrometry, and the benefits and pitfalls of ambient mass spectrometry, as well as the latest developments of the technique, in the analysis of food and environmental parameters. It describes methods that enable the detection of surface materials like waxes, alkaloids, flavors, or pesticides by plainly exposing the corresponding items to the ionization region of the interface, without harm to samples. Features: Explains the theoretical aspects of ambient mass spectrometry Describes how to use ambient MS techniques for food safety, authenticity, and traceability screening Lists the benefits of ambient MS in analysis of food and environmental parameters Covers recent developments of ambient MS in analysis of food and environmental parameters The specialized work provides insight to professionals practicing in food and the environment, including food scientists, food engineers, food biotechnologists, chemical engineers, and those working in research labs, universities, and government regulatory agencies.

Download or read book White Biotechnology for Sustainable Chemistry written by Maria Alice Coelho and published by Royal Society of Chemistry. This book was released on 2015-11-30 with total page 434 pages. Available in PDF, EPUB and Kindle. Book excerpt: White biotechnology is the use of enzymes and microorganisms in industrial production through applied biocatalysis. This allows for milder reaction conditions (pH and temperature) and the use of more environmentally-compatible catalysts and solvents. This, in turn, leads to processes which are shorter, generate less waste, making them both environmentally and economically more attractive than conventional routes. This book describes the use of white biotechnology within the sustainable chemistry concept, covering waste minimization; the use of alternative solvents (supercritical fluids, pressurized gases, ionic liquids and micellar systems) and energies (microwaves and ultrasound); sustainable approaches for the production of fine and bulk chemicals (aromas, polymers, pharmaceuticals and enzymes); the use of renewable resources and agro-industrial residues; and biocatalysts recycling. Covering industrial processes and new technologies, this book combines expertise from academia and industry. It is a valuable resource for researchers and industrialists working in biotechnology, green chemistry and sustainability.
