This book addresses all those who wish or need or care to know about the "state of the art" and the impact of modern chemistry upon the Earth's environment and the quality of life itself. An introductory chapter gives a non-mathematical account of basic chemical knowledge needed to appreciate the effects of chemistry. Then follow examples of the significance and importance of selected chemical elements and compounds in our daily lives. The broad discussion shows how the physical sciences of physics, metallurgy, geology and engineering, and the biological sciences of biology, biochemistry and microbiology, have contributed and applied their scientific principles to our use of the Earth's resources. There is interplay throughout on the industrial use of chemicals, and their beneficial and harmful effects. Dr. Barrett points out and highlights the numerous and beneficial contributions that chemists have made to industry, agriculture, medicine and other human activity. He also wears the mask of the Devil's Advocate by sounding a warning note on the toxic and otherwise harmful effects and consequences that improper use of chemicals can bring about.
