Food Toxicants Analysis covers different aspects from the field of analytical food toxicology including emerging analytical techniques and applications to detect food allergens, genetically modified organisms, and novel ingredients (including those of functional foods). Focus will be on natural toxins in food plants and animals, cancer modulating substances, microbial toxins in foods (algal, fungal, and bacterial) and all groups of contaminants (i.e., pesticides), persistent organic pollutants, metals, packaging materials, hormones and animal drug residues. The first section describes the current status of the regulatory framework, including the key principles of the EU food law, food safety, and the main mechanisms of enforcement. The second section addresses validation and quality assurance in food toxicants analysis and comprises a general discussion on the use of risk analysis in establishing priorities, the selection and quality control of available analytical techniques. The third section addresses new issues in food toxicant analysis including food allergens and genetically modified organisms (GMOs). The fourth section covers the analysis of organic food toxicants.* step-by-step guide to the use of food analysis techniques* eighteen chapters covering emerging fields in food toxicants analysis* assesses the latest techniques in the field of inorganic analysis

This book describes the latest molecular insights needed to understand the chemical and biological (CB) agents and their associated biotechnologies. Its primary focus is to present and discuss molecular technologies such as mass spectrometry, chemical and biological sensors, chromatographic and electrophoretic separation, and comparisons of spectroscopic, immunological and molecular analyses of chemicals used for the detection of chemical and biological agents and to prevent terrorism. This NATO-ASI book also contributes to the critical assessment of existing knowledge on new and important detection technologies. It helps to identify directions for future research and to promote closer working relationships between scientists from different professional fields.

Diet and Health examines the many complex issues concerning diet and its role in increasing or decreasing the risk of chronic disease. It proposes dietary recommendations for reducing the risk of the major diseases and causes of death today: atherosclerotic cardiovascular diseases (including heart attack and stroke), cancer, high blood pressure, obesity, osteoporosis, diabetes mellitus, liver disease, and dental caries.

Microwave-Assisted Sample Preparation for Trace Element Analysis, Second Edition, describes the principles, equipment, and applications involved in sample preparation with microwaves for detecting and analyzing trace elements. Hot topics such as sample preparation for speciation, metabolomics, and halogen determination, as well as the alternatives of sample preparation for special samples (for example, carbon nanotubes, polymers, petroleum products), are also discussed. This completely updated second edition covers all the new devices and more powerful systems that have emerged in the last several years, such as Ultrawave and Ultraclave systems. New challenges in the fields of geology, environmental and biological studies -for example, the need for further determination of rare earth elements and halogens - are currently only covered in scientific journals and not in a comprehensive way. This book offers a summary of the state-of-the-art ways to meet these challenges with microwave-assisted sample preparation. The only book to cover in depth the principles, equipment, and applications of microwave-assisted sample preparation Written by experts in the field who provide a comprehensive overview of the important concepts Introduces the latest devices and systems used for in microwave-assisted techniques, including Ultrawave and Ultraclave systems

The first Workshop on ‘Nuclear Proficiency Testing’ (PT) focused on the new topic appeared at the junction of the nuclear basic research, metrology, quality control in applications, and the new ‘Science of Analytical Performance’ (SAP), namely: ‘how to get/prove the most accurate and precise scientific/technical results in the current practice. Any analytical laboratory should fulfill this goal in order to assure the public credibility of its results, either it is part of the scientific research institute, or a laboratory dedicated to the routine control of the environment, industry, health /medicine, radioprotection, or dosimetry, as the quality of the analytical results and of the services that will be further used depend critically on the accuracy and validity of measurements (EN ISO/IEC Standard 17025: 2005). ‘Proficiency Testing’ plays a central role in this process as the best tool to prove and certify the Laboratory’s Performance & Competence; it belongs to SAP, which, in our case, should be called SNAP (Science of the Nuclear Analytical Performance), as it concerns performance in applications of the nuclear analytical techniques. The ‘PT Workshop-2007’ created the opportunity to learn the criteria / tools used for interpreting the experimental results and evaluating performance, ‘how to fit’ the laboratory’s performance with the rigor of international ‘Proficiency Testing’ evaluation, to understand the basic aspects of methods validation and traceability of the nuclear physical quantities to SI, use of the reference materials and of the statistic criteria for the fitness-for-purpose objectives, advantages of the ILC /PT exercises, and how to get the ‘Excellence’; so, it was primarily a ‘school’ , but not only, because the meeting was also a framework for participants to present their latest results and developments. The unique feature of the ‘PT Workshop-2007’ was the participation –for the first time in a scientific meeting of experts intimately involved in the development of International and National Standards and the organization of international Inter-Laboratory Comparison (ILC) and Proficiency Testing (PT) exercises, of experts involved in radionuclide metrology, who generally establish the norms and requirements for the accuracy of measurements and analytical methods, and experts and specialists involved in nuclear application, as ‘lectors’. Their presence and lessons assured the highest level of knowledge for a successful ‘school’ in the field of Nuclear Proficiency Testing, and the discussions they created were very fruitful, to the benefit of all the participants.

This book is designed to integrate the basic concepts of food safety with current developments and challenges in food safety and authentication. The first part describes basics of food safety, classification of food toxins, regulation and risk assessment. The second part focuses on particular toxins like mycotoxins, aromatic amines, heavy metals, pesticides, and polycyclic hydrocarbons. Recent developments and improvements in the detection of these contaminants are described. The third part deals with the authenticity and adulteration of food and food products, a topic which affects food trade on a national and international level.

The importance of accurate sample preparation techniques cannot be overstated--meticulous sample preparation is essential. Often overlooked, it is the midway point where the analytes from the sample matrix are transformed so they are suitable for analysis. Even the best analytical techniques cannot rectify problems generated by sloppy sample pretreatment. Devoted entirely to teaching and reinforcing these necessary pretreatment steps, Sample Preparation Techniques in Analytical Chemistry addresses diverse aspects of this important measurement step. These include: * State-of-the-art extraction techniques for organic and inorganic analytes * Sample preparation in biological measurements * Sample pretreatment in microscopy * Surface enhancement as a sample preparation tool in Raman and IR spectroscopy * Sample concentration and clean-up methods * Quality control steps Designed to serve as a text in an undergraduate or graduate level curriculum, Sample Preparation Techniques in Analytical Chemistry also provides an invaluable reference tool for analytical chemists in the chemical, biological, pharmaceutical, environmental, and materials sciences.
