在21世纪之初，面临各种环境问题，人类清醒的认识到要走可持续发展之路，而发展环境教育是解决环境问题和实施可持续发展战略的根本。本书是在前几版的基础上进行修订而成的，它是学习环境工程专业更高级课程的基础教程。该书不同于前几版，它将物质和能量平衡单列为一章，并附有200多道新的习题，包括计算机应用问题；书中还更新了成本数据、水质和空气污染标准以及机动车排放控制，并且更新了臭氧消耗、全球变暖、室内空气以及酸雨等部分内容。本书还对于伦理学、噪声污染以及废水处理标准等进行了更广泛、深入的讨论。

本书包含了环境工程导论课程需要的基本的科学与工程原理，可以作为学习环境工程专业更高级课程的基础教程。Davos和Cornwell将可持续发展的理念以及物质与能量平衡作为解决环境工程问题的手段。本书各章后含富有启发性的问题讨论与习题。本书内容丰富、易于理解，可作为高等院校环境类及相关专业的教材，并供从事环境保护的科技工作者参考。
