This book is organized into seven sections encompassing 48 chapters. Section I reviews the anatomy and physiology of human lung. Section II describes the pulmonary response to dust in terms of airway changes and reactions to silica. Sections III and IV deal with lung clearance in animals, the retention, penetration, and elimination of inhaled dusts, and lung deposition and clearance in human. Section V emphasizes the sources of dust inhaled by the human lungs, while Section VI discusses the relationship between pneumonoconiosis and dust exposure. Section VII presents the results of the investigations of dust exposure. This book will prove useful to pulmonologists, toxicologists, and workers in the field of occupational health.
