Trial Objectives

The purpose of this study is to better understand lung diseases that develop from inhaling mineral dust over time.

Although the causes of diseases such as "black lung" and silicosis are known, it is not well understood why some people get these diseases and others don't or how stopping exposure to mineral dust may affect the severity of these diseases. This study will be conducted through phone interviews with participants. The information our researchers collect will be used to learn more about lung diseases with workplace exposure to mineral dusts.

Who Can Participate

Adults who have at least five years of United States based work as a miner or who have been exposed to mineral dusts at work such as silica and who have evidence of lung disease due to mineral dust exposures may be eligible to participate. Medical and work history, chest imaging, pulmonary function testing or any available lung tissue specimens will be collected and analyzed. Family members may donate the lung tissue of a deceased relative if it was saved at a hospital or other health care facility.
