This introductory text explains the fundamentals of the chemistry of the natural environment and the effects of mankind's activities on the earth's chemical systems. Retains an emphasis on describing how natural geochemical processes operate over a variety of scales in time and space, and how the effects of human perturbation can be measured. Topics range from familiar global issues such as atmospheric pollution and its effect on global warming and ozone destruction, to microbiological processes that cause pollution of drinking water deltas. Contains sections and information boxes that explain the basic chemistry underpinning the subject covered. Each chapter contains a list of further reading on the subject area. Updated case studies. No prior chemistry knowledge required. Suitable for introductory level courses.

The Progress and Prosperity of any country mainly depend upon the quality of its human resource,which in turn,depends upon the quality of its educational system.Higher and technical education,being at the apex of the pyramid of education,play a major role in the overall development of any country.One of the major drawbacks of the higher and technical education in our country,is the palpable gap between the world of learning and the world of work.

What does matter look like at the molecular and atomic level? Why are leaves green? Why do colored fabrics fade upon repeated exposure to sunlight? Why does a pencil leave a mark when dragged across a sheet of paper? All of these basic questions have molecular answers that teach and illustrate chemical principles. Nivaldo Tro introduces each concept with a thought experiment, then develops the chemical principles and concepts involved in a molecular understanding of the experiment. Once students have grasped the basic concepts, they are introduced to consumer applications and environmental problems related to the concepts. Mathematical aspects of chemistry are optional.

This guide to environmental chemistry covers major topical issues, including the greenhouse effect, the ozone layer, pesticides, and air and water pollution. The text offers an active problem-solving approach, with exercises incorporated throughout each chapter.

This clearly written, class-tested manual has long given students hands-on experience covering all the essential topics in general chemistry. Stand alone experiments provide all the background introduction necessary to work with any general chemistry text. This revised edition offers new experiments and expanded information on applications to real world situations.
