Background While the association between occupational inhalation of silica dust and
pulmonary tuberculosis has been known for over a century, there has never been a …

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 …

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 …

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

Exposure to crystalline silica dust causes multiple diseases, but silicosis and silica dust-
associated tuberculosis (TB), in particular, are the two diseases that remain high on the list …

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 …

Aims: To examine the effect of silica exposure, in the absence of silicosis, on the prevalence
of pulmonary tuberculosis (PTB), which is epidemic among South African gold miners …

“Silica” refers to crystalline particles formed by the combination of silicon with oxygen.
Inhalation of silica particles promotes the development of pulmonary fibrosis that over …

OBJECTIVES: To investigate the following questions.(1) Is silica dust on its own, without the
presence of silicosis, associated with an increased risk of pulmonary tuberculosis (PTB) in …

Aims: To study the relation between exposure to crystalline silica and silicosis mortality.
Although mortality is an important endpoint for regulators, there have been no exposure …
