Asbestos Report: Disease Data Limitations and MSHA Samples
Read the report from the CDC regarding the lung diseases associated with exposure to asbestos and other carcinogens. This section details the disease data limitations with respect to MSHA samples noted in the final report.
In addition to samples in which quartz was identified, the respirable quartz data reported in Section 3 include MSHA samples identified as: Available exposure data for agents associated with each type of pneumoconiosis are presented in this report following the presentation of mortality data for that same condition. The reader is reminded that the time period over which the exposure data were collected does not necessarily correspond to the time period during which most of the decedents represented in the mortality data acquired their disease. For most pneumoconiosis deaths, there is a latency period of at least several years between first occupational exposure and onset of disease. Subsequent death typically occurs many years after disease onset. Courtesy of the CDC Other helpful links:
