Prolonged exposure to high levels of silica has long been known to cause silicosis This
paper evaluates the evidence for an increased risk of chronic obstructive pulmonary disease …

Occupational exposure is an important risk factor for chronic obstructive pulmonary disease
(COPD), and silica dust is one of the most important occupational respiratory toxins …

Background: Although crystalline silica exposure is associated with silicosis, lung cancer,
pulmonary tuberculosis, and chronic obstructive pulmonary disease (COPD), there is less …

Background Crystalline silica is considered as one of the most common and serious
occupational hazards to workers' health. Although its association with lung cancer has been …

Background The adverse health effects of silica are still a major concern in some industries.
The purpose of this study was to evaluate pulmonary function in a group of sub-radiological …

BACKGROUND A work force based case-control study of lung cancer was performed in non-
silicotic subjects exposed to crystalline silica to investigate the association between silica …

Background: The exposure patterns of respirable crystalline silica based on environmental
records, as well as the link to different diseases, are not well described. Aims and objectives …

Epidemiologic studies of workers exposed to silica were reviewed to identify data on
airborne concentrations of quartz that are not associated with an increased risk of silicosis …

Objective This report investigates epidemiologically whether exposure to silica is associated
with lung cancer risks in individuals without silicosis. Methods We searched the PubMed …

Background Establishing a clear relationship between workplace exposures and cancer is
often difficult. The latent period for cancer development can make it difficult to establish a …
