Loose Leaf for Principles of Environmental Engineering and Science
暫譯: 環境工程與科學原則（活頁本）

Principles of Environmental Engineeringis intended for a course in introductory environmental engineering for sophomore- or junior-level students. This text provides a background in fundamental science and engineering principles of environmental engineering for students who may or may not become environmental engineers.

Principles places more emphasis on scientific principles, ethics, and safety, and focuses less on engineering design. The text exposes students to a broad range of environmental topics--including risk management, water quality and treatment, air pollution, hazardous waste, solid waste, and ionizing radiation as well as discussion of relevant regulations and practices.

The book also uses mass and energy balance as a tool for understanding environmental processes and solving environmental engineering problems.
