Nanotechnology the revolutionary science and art of manipulating matter at the atomic or molecular scale that has cut across such disciplines as chemistry physics biology and  engineering. Despite a largely unproven track record in the environmental arena, nano technology offers great promise for delivering new and improved environmental technologies. However proliferation of nano technology could also lead to new environmental problems, such as new classes of toxins or related environmental hazards. This book is an authoritative, in-depth exploration of the environmental consequences of nano technology. It provides a detailed account of the potential environmental benefits of nano technology, describing environmental technologies as well as other applications that can foster sustainable use of resources. The book will make fascinating and useful reading for engineers, scientists, administrators, environmental regulatory officials, public policy makers, and students in a range of science and engineering disciplines.
