＜p＞Aromas are an integral part of our civilised society. They are not only used in fine perfumes, but also in numerous other articles with which we have daily contact. Another new development has been the agricultural use of aromas as a "biological weapon" to combat insects and other pests. In the field of dermatology, aromas are today among the most frequent sensitizers and may trigger allergic contact eczemas. This volume presents numerous aspects of the topic for the first time in comprehensive form. In an introduction, the chemistry of frequently used aroma components is described, together with the art of perfume composition that has been refined over the centuries. In a chapter on neuropharmacology, the mechanisms of scent recognition are described in detail.＜/p＞画面が切り替わりますので、しばらくお待ち下さい。

＜p＞THE SENSE OF SMELL The nose is normally mistakenly assumed to be the organ of smell reception. It is not. The primary function of the nose is to regulate the temperature and humidity of inspired air, thereby protecting the delicate linings of the lungs. This is achieved by the breathed air passing through narrow passageways formed by three nasal turbinates in each nostril. The turbinates are covered by spongy vascular cells which can expand or contract to open or close the nasal pathways. The olfactory receptors, innervated by the 1st cranial nerve, are located at the top of the nose. There are about 50 million smell receptors in the human olfactory epithelia, the total size of which, in humans, is about that of a small postage stamp, with half being at the top of the left and half at the top of the right nostril. The receptive surfaces of olfactory cells are ciliated and extend into a covering layer of mucus. There is a constant turnover of olfactory cells. Their average active life has been estimated to be about 28 days.＜/p＞画面が切り替わりますので、しばらくお待ち下さい。

＜p＞This book offers a comprehensive and authoritative review of the key environmental areas and compartments where fragrances have been found and discusses the current challenges of their presence and potential hazards. The book starts with a chapter devoted to the manufacturing and characterization of the most relevant types of fragrances, and their emissions to the environment. Subsequent chapters cover topics such as fragrances’ toxic effects on the environment, their major routes of exposure, behaviour, and fate in different environmental matrices. Particular attention is given to ecotoxicological issues and the environmental impact of fragrances in wastewater treatment plants, surface waters, marine environments, soils, remote areas, and air. In this book, readers will find valuable insights into the bioaccessibility and availability of synthetic musks in seafood and the corresponding human exposure and health risks. The book also outlines the most promising analytical methods used for fragrance detection and quantification, and it discusses the risks and future trends in this field.＜/p＞ ＜p＞Written by a multidisciplinary team of expert contributors, and considering its scope, this book is an essential tool not only for scholars and researchers in academia and industry but also for other stakeholders and decision-makers interested in the field of fragrances and their ecotoxicology, as well as environmental impacts.＜/p＞画面が切り替わりますので、しばらくお待ち下さい。

＜p＞The quantity and composition of aroma and avour compounds in foods and food products exert a marked in uence on the consumer acceptance and, consequently, on the commercial value of the products. It has been established many times that one of the main properties employed for the evaluation of the product quality is the avour, that is, an adequate avour composition considerably enhances the m- ketability. Traditional analytical methods are generally unsuitable for the accurate determination of the quantity of this class of compounds. Moreover, they do not contain any useful information on the concentration of the individual substances and they are not suitable for their identi cation. As the stability of the aroma compounds and fragrances against hydrolysis, oxidation and other environmental and tech- logical conditions shows marked differences, the exact determination of the avour composition of a food or food product may help for the prediction of the she- life of products and the assessment of the in uence of technological steps on the aroma compounds resulting in more consumer-friendly processing methods. Furthermore, the qualitative determination and identi cation of these substances may contribute to the establishment of the provenance of the product facilitating the authenticity test. Because of the considerable commercial importance of avour composition, much effort has been devoted to the development of methods suitable for the separation and quantitative determination of avour compounds and f- grancesinfoodsandinotherindustrialproducts.＜/p＞画面が切り替わりますので、しばらくお待ち下さい。

＜p＞Regardless of the subject matter, our studies are always searching for a sense of the universal in the specific. Drawing, etchings and paintings are a way of communicating ideas and emotions. The key word here is to communicate. Whether the audience sees the work as laborious or poetic depends on the creative genius of the artist. Some painters use the play of light passing through a landscape or washing over a figure to create an evocative moment that will be both timeless and transitory. The essential role of art remains what is has always been, a way of human expression. This is the role that our participants concentrate on as they discuss art as the expression of the spirit, a creative act through which the artist makes manifest what is within him. Spirit suggests the unity of feeling and thought. Avoiding broad generalities, our participants address specific areas in orchestration with music, architecture, literature and phenomenology. Profs. Souiller, Scholz, Etlin, Sweetser, Josephs show us at what point art is an intimate, profound expression and the magic of a civilization as a whole, springing from its evolving thoughts and embodying ideals, such as the Renaissance, the Baroque, Modernism and at what point it reflects the trans formation of a particular society and its mode of life.＜/p＞画面が切り替わりますので、しばらくお待ち下さい。

＜p＞Modern flavours and fragrances are complex formulated products containing blends of aroma compounds with auxiliary materials, enabling desirable flavours or fragrances to be added to a huge range of products. The flavour and fragrance industry is a key part of the worldwide specialty chemicals industry, yet most technical recruits have minimal exposure to flavours and fragrances before recruitment. The analytical chemistry of flavour and fragrance materials presents specific challenges to the analytical chemist, as most of the chemicals involved are highly volatile, present in very small amounts and in complex mixtures.＜/p＞ ＜p＞＜em＞Analytical Methods for Flavor and Fragrance Materials＜/em＞ covers the most important methods in the analysis of flavour and fragrance materials, including traditional and newly emerging methodologies. It discusses the capabilities of the various analytical methods for flavour and fragrance analysis and guides the newcomer to the most appropriate techniques for specific analytical problems.＜/p＞画面が切り替わりますので、しばらくお待ち下さい。

＜p＞Over the last decade, synthetic musk fragrances, which after use enter the environment by different pathways, have been described as a new group of bioaccumulative and persistent xenobiotics. This book gives the first comprehensive and up-to-date overview of the environmental pollution caused by several different synthetic musks. Written by a wide range of international experts in the field, the book summarizes and critically discusses the musk levels in the different compartments of the aquatic environment, in indoor/ambient air, house dust, and in addition, in human samples. The aspects of biotransformation and metabolism of several synthetic musks in the environment and in animals/humans are particularly emphasized. Finally, a provisional toxicological assessment and risk evaluation is given. Many, as yet unpublished, data complete this survey. The volume also points out the gaps, the still missing toxicological and environmental data, and in general, the need for further research work in this field.＜/p＞画面が切り替わりますので、しばらくお待ち下さい。
