Analytical chemistry is a science with applications throughout medicine, industry, environment, and indeed, seemingly all of the sciences. Quoting from the 2007 WebSite of the Division of Analytical Chemistry of the American Chemical Society Analytical Chemistry seeks ever improved means of measuring the chemical composition of natural and artificial materials. The techniques of this science are used to identify the substances which may be present in a material and to determine the exact amounts of the identified substances . 

A wide variety of natural and anthropogenic materials and chemicals are recognized to influence human health. In this chapter, we consider earth materials to include a fairly broad range of solids and gases that are produced by namral earth processes are liberated from the earth as a result of human activities or that are produced from the earth by humans and transformed for use in society. Examples of earth materials that have been the focus of health concerns (Tables 1 and 2) include ...

In the age of raising industrial production the problem of environmental protection becomes a vital aspect in all questions of the human society. The problem involves questions of careful utilization of natural resources (raw materials and energy), the prevention of useless or harmful side-products, environmentally-tayloring of products, and the environmentally acceptable elimination (better recycling) of consumed products. Chemical industry in the widest meaning plays a major role in the solution of these questions. Also electrochemistry can contribute as its main scientific interest lays in the interaction of energy and chemical matter. Thus, in this paper one aspect among several others is mentioned which may play a role in the efforts to find new ways of the protection of the environment.

Shiba, Tetsuo (p. 222, Plate 43) born in Hiroshima Prefecture, Japan in 1924, received his Ph.D. degree at Osaka University in 1959. After having studied at the National Institute of Health, Bethesda, USA, as Visiting Scientist for two and a half years, he returned to Osaka University as Associate Professor in 1962. In 1971 he was appointed Professor, Laboratory of Natural Product Chemistry, Department of Chemistry, Faculty of Science, Osaka University. Here he developed his structural and synthetic studies on biologically active substances (peptides and others). In the meantime, he served as Vice President of the Chemical Society of Japan, and now as a Member of the Science Council of Japan. He successfully planned the Japan Symposia of Peptide Chemistry and the first international Symposium of Peptide Chemistry in Japan as President of the Organizing Committee in 1987. 

The opening sentence of this text is, Chemistry is an active, evolving science that has vital importance to our world, in both the realm of nature and the realm of society. Throughout the text, Chanistry in Action and Chemical Mysteries give specific examples of chanistry as active and evolving in all facets of our lives. 

Color measurement n. Color is a manufactured object is normally obtained by applying a colorant (dye or pigment) to al polymer substrate, such as textile, paper or paint medium. The appearance of such surface colors depends on (1) the nature of the prevailing illumination, (2) the interaction of the illuminating radiation with the colored species in the surface layers, and (3) the ability of the radiation that is transmitted, reflected and scattered from the colored surface to induce the sensation of color in the human eye/brain system. Color measurement consists of the physical measurement of light radiated, transmitted, or reflected by a specimen under specified conditions, and mathematically transformed into standardized colorimetric terms, which can be correlated with visual evaluations of colors relative to one another.
