Colorimetry is concerned with the measurement of, and discrimination between, colours. These are important topics in a wide range of the physical sciences, life sciences, and computing and engineering. Examples of specific areas where the techniques of colorimetry are used are: manufacturers of paints, textiles, plastics and cosmetics (and quality controllers in these industries), those interested in the effect of light in human environments (for example, in terms of its direct effects on the eye, laser safety and design of eye protection and ergonomics of hospital lighting), psychology, physiology and those involved in the technical aspects of photography. The book presents the physiological background behind how colour is perceived and discusses sources of visible radiation, before going on to describe in detail colorimetric techniques for measuring and discriminating between colours. Applications of these techniques are discussed and relevant mathematical data is provided. The book gives a comprehensive account of the physiological aspects of colour, the development of photometry and colorimetry, and applications of colorimetry in a single volume.

In the early twentieth century lead had many domestic uses: in solder for cans, as a gasoline additive to prevent ""knocking"" in engines, in water pipes, and, most prominently, in interior paint prized for its durability and ability to hold color. Far from being the toxic hazard we recognize today, lead was a valuable commodity. However, by the end of the century, lead had largely disappeared from our environment as physicians discovered the threat it posed to children's health and mental development. Old Paint documents the history of lead-paint poisoning in the United States and the evolving responses of public health officials and the lead-paint industry to this hazard up to 1980, by which time lead had been banned from gasoline and paint. Peter C. English traces lead poisoning from a rare, but acute problem confined to a small group of children to the discovery by the end of the 1940s of the dangers of the crumbling lead-painted interiors of inner-city dwellings. He draws on a wide range of primary materials not only to illuminate our understanding of how this health hazard changed over time, but also to explore how diseases are constructed and evolve.

This treatise pertains to dyes composed of a central polymethine moiety and two cyclic terminal subunits. The polymethine linker can be unsubstituted or substituted, and at least one terminal subunit is a heterocyclic system. The classes of compounds reviewed range from classical cyanines, ?rst s- thesized in the 1850s, to hemicyanines, to styryl dyes, to merocyanines, to coumarinpolymethines, andtosquarylium dyesthatweresynthesized forthe ?rst time in the 1960s. These structurally diverse classes of compounds have one commondenominator, namely electronconjugation that involves the t- minalheterocyclic/aromaticsubunitsandthecentralpolymethinelinkerofthe molecule. Such conjugated molecules show absorption and ?uorescence that are a function of the structure of the three moieties. By changing the length and substitution of the polymethine linker and/or the structures of the t- minal moieties, molecules can be designed with absorption and ?uorescence ranging from the blue visible region (> 400nm) to the near-infrared region (> 700nm) of the electromagnetic spectrum. The synthetic developments of the last decade are reviewed and references to older but important work are provided tohelpdesignadye ofinterest fora desired speci?c application.

Today synthetic dyes are used extensively in the textile dyeing, paper printing, color photography, pharmaceuticals, food and drink, cosmetic and leather industries. As of now, over 100,000 different dyes are available, with an annual production of over 700,000 metric tons. These industries discharge an enormous amount of colored effluents into natural water bodies, with or without treatment. The textile industry alone discharges 280,000 tons of dyes every year, making it the largest contributor to colored effluent discharge. Although a variety of treatment technologies are available, including adsorption, chemical oxidation, precipitation, coagulation, filtration electrolysis and photodegradation, biological and microbiological methods employing activated sludge, pure cultures, microbial consortia and degradative enzymes are economically viable, effective and environmentally responsible options. As such, this book gathers review articles from international experts working on the microbial degradation of synthetic dyes, offering readers the latest information on the subject. It is intended as a quick reference guide for academics, scientists and industrialists around the world.

World-wide environmental legislation limiting the use of solvent based ink systems of the preceding decades has resulted in the development of a substitute and more environmentally safe alternative utilizing water base technologies. This has resulted in an enormous research and development effort by a multiplicity of related industries. Because of the tremendous evolution brought about by these changing technologies it has been extremely difficult for the water base ink chemist to keep abreast of the latest innovations. This book provides a working knowledge of the chemistry and technology of water base ink systems for chemists and engineers in the industry. It provides a foundation in all aspects of the industry, from the perception of color theory to the final starting point formulations. The articles in this volume have been specifically picked out to enlighten some of the most difficult problem areas in formulation and development. Highly practical, it is written by authors with many years of experience in the industry, ensuring commercial relevance throughout.

Lead-based paint has become a national issue and will continue to be a hi- priority focus ofnational, state, and local agencies until there is no lead-based paint in the United States. Lead-based paint has become a tremendous health hazard for people and animals. Lead-based paint has been in widespread use throughout Europe and the United States. Lead has been known to be a health hazard since the time ofPliny the Elder (A. D. 23-79), but it was deemed that the advantages of lead in paint outweighed the health hazards. There has been a change in outlook, and in 1973 the U. S. Congress banned all lead paint from residential structures. A voluminous number of law suits have been initiated since, and continue to be litigated with the purpose of determining the parties responsible for the lead poisoning of children and others and to exact the indemnities. Lead-based paint is still authorized for use on bridges and nonresidential structures, and thousands of city, state, military, and federal government housing projects still contain lead-based paint. This paint must be removed if these dwellings are to be safe living quarters, especially for children. Aba- ment techniques continue to be evaluated; some have been used successfully. Lead-based paint abatement will continue into the next century, and it is hoped that this comprehensive volume will serve as a guide for those seriously interested in this important subject.

Synthetic fibres are widely used for many applications, with their colour being of major commercial importance. This extensively referenced book provides a comprehensive account of the physical chemistry of the dyeing of synthetic fibres and microfibres.

The ancient Oriental dyestuff madder red was avidly sought by Europeans and finally cracked by the French in 1760, and it became the main crop in the Caspian Caucasus. The quest for Turkey Red spurred an avalanche of research that led to its chemical synthesis in 1870 and subsequently the collapse of the world-wide madder industry.

Volume 3, like the preceding volumes, focuses on the diversity of surfactants, both in terms of chemical structure and physico-chemical / surface active properties. These properties may be predictable for simple molecules but, for most commercial surfactants (which may be regarded as multi-component blends), this is not so easy. Yet it is important to develop a greater understanding of the interactions within a multi-component mixture, in order to select the most appropriate product for a particular application in which a combination of surface active properties is required.

A special feature of this volume is the initial chapter, in which the end uses of surface active agents are classified by industrial sector and the surfactant properties required for each application are presented in detail. The result is a unique guide to the influence of chemical structure on performance in end use, highlighting the benefits of particular surfactants and illustrating how some of the newer classes of surfactant may overcome the deficiencies of previously used products.

This book provides guidance on removing graffiti and protecting surfaces from further attack. It is based on experience built up by London Underground Ltd of dealing with the problem in their trains, buildings, platforms, passageways, public lavatories, bridges and other structures. It is designed to serve as a reference source for anyone who is responsible for managing and maintaining public areas prone to graffiti, and to those who supervise and carry out graffiti removal operations. Guidance on graffiti types, removal agents and equipment is given, effective mechanical and chemical treatments are explained and a series of easy-to-use guidance sheets detailing 15 proven graffiti removal methods are included. Common target locations are described, and the importance of identifying and understanding the nature of the surface before selecting the appropriate graffiti removal method is emphasized. Getting rid of graffiti lays special emphasis on safe working practices to minimize risk and takes account of current UK Health and Safety at work and COSHH legislation. Addresses of relevant sources of information and specialist materials and equipment are given in an appendix.

Colouring Textiles is an attempt to provide a new cross-cultural comparative approach to the art of dyeing and printing with natural dyestuffs in the eighteenth and nineteenth centuries. Divided into thematic chapters, it uncovers new data from the vast historical heritage of natural dyestuffs from a range of European cities, to present new historiographic insights for the understanding of this technology. Through a sort of anatomic dissection, the book explores the study and cultivation of dye-plants in botanical gardens and plantations, and the tacit values hidden in dyeing workshops, factories, laboratories, or national and international exhibitions. It metaphorically submits the natural dyestuffs of the eighteenth and nineteenth centuries to a series of systematic historical tests, and traces back the circulation of those sources of colours through colonial spaces, dye works, cross-cultural networks, schools of artistic design, and science-based industries for the making of synthetic colorants. Colouring Textiles contributes to a better understanding of the role of natural dyestuffs in the processes of industrialization in Western Europe. Audience: Historians of science and technology, historians of chemistry, philosophers, economic historians, professional chemists, arts and crafts historians, and cultural anthropologists.
