The most comprehensive book to date on the history of silicosis and the strategies used to combat it. Despite the common perception that "black lung" has been relegated to the dustbin of history, silicosis remains a crucial public health problem that threatens millions of people around the world.

Three types of silicosis occur: Chronic silicosis, which results from long-term exposure (more than 20 years) to low amounts of silica dust. The silica dust causes swelling in the lungs and chest lymph nodes.

The Hawks Nest Tunnel disaster was a large-scale incident of occupational silicosis as the result of the construction of the Hawks Nest Tunnel near Gauley Bridge, West Virginia, as part of a hydroelectric project. This project is considered to be one of the worst industrial disasters in American history.

Introduction. Silicosis is caused by occupational exposure to silica and is one of the leading occupational diseases worldwide (James SL et al., ).Although efforts to reduce silica exposure have been made for many decades, millions of workers are still exposed to silica worldwide, especially in developing countries (Cohen et al., ; James SL et al., ).

"This book embodies a fascinatingly diverse set of chapters that have been successfully integrated into a refreshing narrative of not only health and medical aspects of silicosis, but also important social, economic and public health aspects of this ultimately preventable : Paul-André Rosental.

Silicosis is a condition caused by inhaling too much silica over a long period of time. Silica is a highly common, crystal-like mineral found in sand, rock, and quartz.

Silicosis is caused by inhalation of unbound (free) crystalline silica dust and is characterized by nodular pulmonary fibrosis. Chronic silicosis initially causes no symptoms or only mild dyspnea but over years can advance to involve most of the lung and cause dyspnea, hypoxemia, pulmonary hypertension, and respiratory impairment.

Silicosis: Years of potential life lost to age 65 and to life expectancy by race and sex, U.S. residents age 15 and over, – May Silicosis: Number of deaths, crude and age-adjusted death rates, U.S. residents age 15 and over, – Silicosis is a notified disease under the Mines Act () and the Factories Act ().

It should also be made a notifiable disease under the Public Health Act (), so that reporting becomes mandatory. Awareness campaigns are needed to sensitize workers about their risk of silicosis, personal protective measures and early symptoms.

Silicosis is disease produced by inhalation of one of the forms of crystalline silica, most commonly quartz (see Section 2 for mineral subtype definitions).There are several different clinical and pathologic varieties of silicosis, including simple (nodular) silicosis, acute silicosis (silicoproteinosis), complicated pneumoconiosis (progressive massive fibrosis), and true diffuse interstitial.

Accelerated silicosis, which is rare, may develop after more intense exposures over several years or months (like acute silicosis). Silica is also a cause of lung cancer. When inhaled, silica dust passes into the lungs, and scavenger cells such as macrophages engulf it (see Overview of the Immune System).

By studying this interplay in the 20 th century, both in industrialized and emerging and developing countries, the book makes silicosis a crucial test-case for rethinking social and health regulations.
