Our intention in publishing this book was to discuss and interpret all of the major issues in the chemical and environmental science disciplines, because this book covers such a broad range of chemical and environmental science research area. Rather, we have selected the themes and challenges, briefly defined them and demonstrated how they connect, clarified the terminology, and indicated where further research may be accessed. We hope that the result is an excellent introduction to 'chemical and environmental science. It is primarily aimed towards researchers in chemical science and related fields, but it should be accessible to new researchers as well. We have explored into more depth on issues that have received little attention elsewhere. There are several useful sources for topics such as chemical science, environmental science, nanotechnology, ionic liquids, solid waste management, photodegradation, Nanomaterial, adsorption of hazardous metals, and conducting polymers.

However we attempted to provide up-to-current knowledge, we are well aware that books may soon go out of date if they seek to provide too much detail, so we concentrated on basic concepts that should not go out of fashion too quickly. Our book differs somewhat from other texts in the chemical and environmental sciences in its concentration. We have focused on ideas and theories because we feel that a solid grasp of them will be more useful in the long run than specifics of present systems, services, and approaches. We've also highlighted the dimension since we feel it's critical to understand where the discipline and its components originated from and why some things are the way they are.

This approach is based on the research, with several references provided at the end of each chapter for convenience. Our intention is that the content of this book will be sufficient to provide a fundamental knowledge of the entire field, and that readers will refer to the references for more information and examples of the parts of which they are most interested. The conclusion words and captions, as well as the important references, at the conclusion of each chapter are intended to present the main points in a factual way.
