This newly updated reference uses scientific laws, principles, models, and concepts to provide a basic foundation for understanding and evaluating the impact that chemicals and technology have on the environment. Designed for both professional and student use, the new Second Edition includes recent improvements in the application of new technologies and materials on the environment. It places greater emphasis on the three environmental media of air, water, and soil and discusses how technology can be used to mitigate contamination of all three. This edition has been made even more user-friendly by communicating with more environmental terms and fewer scientific ones. Major topics covered include connections between environmental science and technology, air quality, water quality, soil science, and the impact of solid and hazardous waste on the environment. Each chapter includes a list of objectives, discussion questions, and a bibliography for further research.
