Objectives Chronic obstructive pulmonary disease and silicosis are associated with
exposure to crystalline silica. We determined the exposure to respirable crystalline silica and …

The lifetime risk of silicosis associated with low-level occupational exposure to respirable
crystalline silica remains unclear because most previous radiographic studies included …

Background Crystalline silica (CS) exposure can cause serious lung disease in humans, but
mechanisms of pulmonary toxicity have not been completely elucidated. Aims To assess pro …

Background Occupational exposure to artificial stone, a popular material used for
countertops, can cause accelerated silicosis, but the precise relationship between silica …

Background In metal and nonmetal (M/NM) mines in the United States, respirable crystalline
silica (RCS) exposures are a recognized health hazard and a leading indicator of respiratory …

Background Exposure to respirable crystalline silica (RCS) causes emphysema, airflow
limitation and chronic obstructive pulmonary disease (COPD). Slate miners are exposed to …

Occupational exposure to respirable crystalline silica (RCS) is common in a range of
industries, including mining, and has been associated with adverse health effects such as …

Background Respirable crystalline silica (RCS) has been associated with severe health
risks. Exposures in Western Australia (WA) have been typically high in hard‐rock mining and …

Objective: To evaluate silica exposure and respiratory disease in granite workers. Methods:
A cross-sectional study of 440 active granite workers. Results: Seventy-seven (17.5%) have …

Occupational exposures to respirable crystalline silica are associated with the development
of silicosis, lung cancer, pulmonary tuberculosis, and airways diseases. These exposures …
