Much of the more than 30 million tons of asbestos used in the United States since 1900 is still present as insulation in offices and schools, as vinyl-asbestos flooring in homes, and in other common products. This volume presents a comprehensive evaluation of the relation of these fibers to specific diseases and the extent of nonoccupational risks associated with them. It covers sources of asbestiform fibers, properties of the fibers, and carcinogenic and fibrogenic risks they pose.

Humanity’s ever-increasing hunger for mineral raw materials, caused by a growing global population and ever increasing standards of living, has resulted in economic geology becoming a subject of urgent importance. This book provides a broad panorama of mineral deposits, covering their origin and geological characteristics, the principles of the search for ores and minerals, and the investigation of newly found deposits. Practical and environmental issues that arise during the life cycle of a mine and after its closure are addressed, with an emphasis on sustainable and "green" mining. The central scientific theme of the book is to place the extraordinary variability of mineral deposits in the frame of fundamental geological processes. The book is written for earth science students and practicing geologists worldwide. Professionals in administration, resource development, mining, mine reclamation, metallurgy, and mineral economics will also find the text valuable. Economic Geology is a fully revised translation of the the fifth edition of the German language text Mineralische und Energie-Rohstoffe.
