Book Description
The participation in interlaboratory studies and the use of Certified Reference Materials (CRMs) are widely recognised tools for the verification of the accuracy of analytical measurements and they form an integral part of quality control systems used by many laboratories, e.g. in accreditation schemes. As a response to the need to improve the quality of environmental analysis, the European Commission has been active in the past fifteen years, through BCR activity (now renamed Standards, Measurements and Testing Programme) in the organisation of series of interlaboratory studies involving expert laboratories in various analytical fields (inorganic, trace organic and speciation analysis applied to a wide variety of environmental matrices). The BCR and its successor have the task of helping European laboratories to improve the quality of measurements in analytical sectors which are vital for the European Union (biomedical, agriculture, food, environment and industry); these are most often carried out in support of EC regulations, industrial needs, trade, monitoring activities (including environment, agriculture, health and safety) and, more generally, when technical difficulties hamper a good comparability of data among EC laboratories. The collaborative projects carried out so far have placed the BCR in the position of second world CRM producer (after NIST in the USA).Interlaboratory Studies and Certification of Reference Materials for Environmental Analysis gives an account of the importance of reference materials for the quality control of environmental analysis and describes in detail the procedures followed by BCR to prepare environmental reference materials, including aspects related to sampling, stabilization, homogenisation, homogeneity and stability testing, establishment of reference (or certified) values, and use of reference materials. Examples of environmental CRMs produced by BCR within the last 15 years are given, which represent more than 70 CRMs covering different types of materials (plants, biological materials, waters, sediments, soils and sludges, coals, ash and dust materials) certified for a range of chemical parameters (major and trace elements, chemical species, PAHs, PCBs, pesticides and dioxins).The final section of the book describes how to organise improvement schemes for the evaluation method and/or laboratory performance. Examples of interlaboratory studies (learning scheme, proficiency testing and intercomparison in support to prenormative research) are also given.

Book Description
Analytical Methods for Pesticides and Plant Growth Regulators, Volume XV: Principles, Statistics, and Applications covers general principles of pesticide analysis and application of the techniques. The book discusses methods dealing with the analysis of pesticide formulations and residues in biological systems, food, and the environment; government regulations for the safe use of pesticides; and the rationale for the need for pesticide analyses. The text also describes the statistics of sampling and analyses, including the application of computers; clean-up techniques; and the international acceptance and interlaboratory comparisons of pesticide residue data. A discussion, review, and description of analytical methods to meet the unique requirements imposed by analyses of active ingredients in formulations (finished products), pesticide residues in foods and the environment, and pesticide metabolites in plants and animal tissues (metabolism studies) are also considered. People involved in pesticide analysis will find the book invaluable.

Book Description
This book deals exclusively and comprehensively with the role of proficiency testing in the quality assurance of analytical data. It covers in detail proficiency testing schemes from the perspectives of scheme organisers, participant laboratories and the ultimate end-users of analytical data. A wide variety of topics are addressed including the organisation, effectiveness, applicability, and the costs and benefits of proficiency testing. Procedures for the evaluation and interpretation of laboratory proficiency, and the relation of proficiency testing to other quality assurance measures are also discussed. Proficiency Testing in Analytical Chemistry is an important addition to the literature on proficiency testing and is essential reading for practising analytical chemists and all organisations and individuals with an interest in the quality of analytical data.

Book Description
Quality control and assurance cover a diverse area of modern life and play, undeniably, an important role. This book brings together a collection of international papers that showcase examples of current research and practice in industry and the medical profession. It is hoped that engineers, researchers and scientists will be assisted in their continuous quest for excelling in qualitative aspects. The Ancient Greek word arete means excellence or virtue and defines the highest qualitative state: a mans effectiveness and skill in goodness (optimum potentiae). Indeed, Ancient Greeks believed that without quality control, specifications are useless and may result to illegitimacy, which in turn may become a threat to society itself.

Book Description
Pesticide Residues: A Contribution to their Interpretation, Relevance and Legislation contains the papers presented at two special Symposia held in the Pesticide Residues Section at the Fourth International Congress of Pesticide Chemistry (lUPAC). This book is organized into two parts encompassing 17 chapters. Part I focuses on the accuracy of any statement on the amount of residue a sample contains, which is influenced by the interaction of multiple factors. This part specifically discusses some of these factors and their bearing on the analytical result of pesticide residue analysis. Part II deals with the complex problem of whether and how the unavoidable uncertainties in analytical findings can be matched to a legislative machinery accustomed to operating with rigid data. This part also covers the principles for the permission of pesticides from the food-hygienic point of view, with emphasis on regulatory toxicology and tolerances of pesticide residues. This book will be of value to toxicologists, agriculturists, public health workers, and legislators.
