Worker Health Study Summaries

Research on long-term exposure

At NIOSH, we feel it is important to share information about our studies. This page provides summaries of worker health studies that have been done over the years.

These summaries, or worker notifications, were sent to those workers who were included in each study. We cannot reduce past exposures, but knowing about possible health problems can allow for better health monitoring and early disease detection. Most illnesses are treatable or manageable if found early. We hope those workers who are still exposed to these materials will become more aware of possible health effects and take steps to better protect themselves.

If you work with any chemical or possible hazardous material, always tell your doctor. Informing your doctor of job exposures can allow for better health monitoring to reduce future health problems.

If you have any questions about these study summaries, contact us by calling 800-CDC-INFO.

NOTICE: Many of these are NIOSH Archive Documents, and may not represent current NIOSH Policy.
