Mining Exposures and Health

Mining Exposures and Health

The Project Continues

As part of its ongoing occupational disease cluster work with McIntyre Powder-exposed mine workers, OHCOW established an interdisciplinary team of doctors and specialists. Exposed miners report multiple diagnoses and/or symptoms related to exposure to McIntyre Powder (aluminum oxide dust) and the mining environment more generally, including cancers, respiratory and cardiovascular ailments, neurological conditions, and other health conditions. OHCOW Medical Consultants and Occupational Hygienists continue to complete literature reviews on issues common to groups of miners.

Links to the reports are provided below, and will be updated regularly.
