Although the research actIvItIes of dyestuff chemists worldwide have been influenced to a great extent, in recent years, by the need to respond to a variety of environmental issues associated with the manufacture and application of synthetic dyes and pigments, a significant level of targeted research continues to be devoted to new chemistry aimed at enhancing the technical properties of dyes in commerce. This book is a presentation of various aspects of basic research conducted during the past decade but not reported in the recent review literature. The coverage herein is unique in that it emphasizes systematic approaches commonly utilized in the design and synthesis of dyes and pigments and the required intermediates. While it is well known that certain transition metals are important in the synthesis of technically viable metallized dyes for polyamide and protein fibers, these metals are demonstrated in Chapter 1 also to be effective agents in the regiospecific placement of substituents into azo compounds. The scope and limitations of this chemistry are presented. In other synthetic work, a description of the different processes employed to produce the major families of reactive dyes is presented. In Chapter 4, special attention is given to reactive dyes containing more than one reactive group, and to the more recent developments in the field. The two chapters which follow provide a review of the recent literature pertaining to novel chromophores and dyes for the D2T2 process, respectively.
Man’s environment is pervaded by ionizing radiation of predominantly natural origin but now with an important contribution from anthropogenic activities. Exposure to ionizing radiation can have serious health implications, which is why it is of concern to us. This book brings together under one cover, the fundamentals of radiological protection, the techniques used for measuring radioactivity and radionuclides and the methods for modelling the dispersion of radionuclides in the environment. Information on radioactive decay, the interaction of ionizing radiation with matter and biological effects of radiation is provided in a form that enables the reader to quickly appreciate its importance to the environment and human health. Summaries of the effects of past releases, including the Chernobyl accident, are included as well as examples of applications of models to calculate and predict concentrations of radionuclides in our environment. This book is aimed at all those studying, at undergraduate and graduate levels, radioactivity in the environment and its impact on man. It will also serve as a handbook for workers in the fields of radiochemical analysis and environmental modelling and for scientists, consultants and environmental health and pollution officers who have to provide radiological data or information for legislative and related purposes.
