Our intention has been to provide a short introduction to the chemistry and mode of action of insecticidal phosphoric acid compounds, with particular reference to the relationship between structure and activity. The yearly production of these pesticides is now approaching 100,000 tons and thus offers an important example of applied research. If, however, one examines the historical develop ment of these compounds, it is apparent that this was preceded by a hundred years of pure chemistry of phosphorus. The utility of the phosphoric acid pesticides is undisputed today - and furthermore it can be expected that they will solve many of the world's nutritional problems" yet from this field of applied research many paths are now leading back into basic research in chemistry, biochemistry, biology and toxicology etc. This clearly illustrates the problem of attempting to define pure and applied research. Originally, this book was conceived for students of chemistry who, on completion of their study, were uncertain about the place of applied research in industry but it was soon clear that such material, when supplemented with further data, would serve as an introduction to the field of pesticidal phosphoric acid compounds for many technicians, officials and scientists who, in various authorities in agriculture, in chemical and biological research, are concerned with the problems of crop protection and more recently with questions of pollution of the environ ment.

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.

In order to get a general concept of organophosphorus pesticides with such a variety in structure and biological activities, consideration of each aspect of chemistry, biochemistry, and the applied sciences is necessary. This book consists of these three main parts. After the presentation of the background of phosphorus chemistry in Chapter 1, stress was put on the chemical and biochemical reactions of organophosphorus pesticides, including synthesis, analysis, metabolism mode of action, and other interesting aspects in Chapter 2 to 4, and on the structure-pesticidal activity relationship in Chapter 5.

This book provides recent information on various analytical procedures and techniques, representing strategies for reliability, specificity, selectivity and sensitivity improvements in pesticides analysis. The volume covers three main topics: current trends in sample preparation, selective and sensitive chromatographic detection and determination of pesticides residues in food and environmental samples, and biological (immunoassays-and biosensors-based) methods application in pesticides analysis as an alternative to the chromatographic methods for "in situ" and "on line" pesticides quantification. Intended as electronic edition, providing an immediate "open access" to its content, the book is easy to follow and will be of interest to the professionals involved in pesticides analysis.

Professor Albert S. Perry passed away suddenly on February 18, 1992, leaving behind his grieving family, friends and colleagues. It was his aspiration to produce a comprehensive work on insecticides to summarize his lifelong dedication to the field of entomology and public health. On the day before his operation, he expressed his desire with the following words: . "1 am coming out of this surgery and will recuperate from it as soon as possible for the sake of my boy (then aged three) and the book". He also told me that he would like to add a chapter on IPM (Integrated Pest Management) and suggested that we write it together. The sad reality is that none of this took place the way he had planned and these became his last words. On my own, I found it difficult to proceed with the writing of the IPM chapter, since several chapters are required to cover· this subject and, in fact, several books. are already devoted to IPM. There was even an IPM article written in a journal (Awake 1983) for a general audience to which he commented that he would like to use it someday because it was well written for laymen, thus providing the readers a wide selection of journals and books to choose from.

Chemicals are used worldwide to protect crops and structures, manage pests, and prevent the spread of disease. While beneficial to society, these pesticides can pose human health and environmental risks. Pesticides provides a comprehensive and international collection of data concerning the substances used to repel or mitigate pests ranging from insects, animals and weeds to microorganisms. A valuable feature of this reference is its organization by functional category. The 1,844 chemical entities are divided into the following 17 functional categories: Acaricides, Algicides, Animal Repellants, Bactericides, Bird Repellants, Fungicides, Herbicides, Insecticides, Molluscicides, Nematicides, Piscicides, Plant Growth Regulators, Rodenticides, Safeners, Slimicides, Termiticides and Miscellaneous Chemicals. This compilation provides important chemical and toxicity data for the 1800 substances registered by the US Environmental Protection Agency and used largely in the agricultural environment. The chemical, physical and bioactivity properties of each agent are recorded along with a comprehensive listing of product trade names and synonyms as well as manufacturers. The EPA status of each agent is given and each record carries the appropriate CAS Registry Number and the associated EINECS Number where available. The Merck Index number is provided for all chemicals in this edition which also appear in the 13th edition of the Merck Index. Wherever possible, the following information is also displayed for each entry: melting point, boiling point, density or specific gravity, refractive index, optical rotation, ultraviolet absorption, and solubility as well as chronic and acute toxicities. A key strength of this new reference is the extensive coverage of synonyms. The book includes an index of 28,000 chemical synonyms and trade names with a cross-reference to their main entry. This extraordinarily comprehensive view of trade name and generic synonyms makes Pesticides one of the world's most exhaustive references for agricultural chemical synonyms.

The proposed book mainly sorts out emerging and burning issues faced day to day by municipal and industrial wastewater treatments. It also provides a comprehensive view of recent advances in hybrid treatment technologies for wastewater treatment, addresses the current limitations and challenges of applying these tools in wastewater treatment systems. This book gives an insight about recent developments in membrane technology for wastewater treatment. Industrial wastewater contains a large variety of compounds, such as heavy metals, salts and nutrients, which makes its treatment challenging. Thus, the use of conventional water treatment methods is not always effective. In this sense, membrane-based hybrid processes have emerged as a promising technology to treat complex industrial wastewater. The present book analyses and discusses the potential of membrane-based hybrid processes for the treatment of complex industrial wastewater along with the recovery of valuable compounds and water reutilization. In addition, recent and future trends in membrane technology are highlighted. FEATURES The properties, mechanisms, advantages, limitations and promising solutions of different types of membrane technologies are discussed The optimization of process parameters is addressed The performance of different membranes is described The potential of nanotechnology to improve the treatment efficiency of wastewater treatment plants is presented The application of membrane and membrane-based hybrid treatment technologies for wastewater treatment is covered
