McIntyre Powder Project

  • 500 Mine workers on MPP Voluntary Registry

    In April 2015, the McIntyre Powder Project began compiling a voluntary registry, documenting health issues experienced by mine workers (and in one case, a factory worker) who had been exposed to McIntyre Powder aluminum dust.  To date, 500 workers have registered with the McIntyre Powder Project or were registered by their surviving next of kin.  Nearly 200 are deceased - 38 of whom died since the MPP voluntary registry was established. 

    Most of the workers have multiple diagnosed health conditions and/or symptoms, with respiratory problems affecting 317 (172 with diagnosed conditions, 145 with symptoms but no diagnosis, 12 have sarcoidosis).  Neurological conditions were reported for 153 workers, including 99 with diagnosed conditions and 58 with symptoms but no diagnosis (55 of which involved memory issues).  Of the diagnosed neurological conditions, there are 44 with Parkinson's, 31 with Alzheimer's, 17 with dementia, and 7 with Amyotrophic Lateral Sclerosis (ALS, also known as Lou Gehrig's disease).  121 workers report cardiovascular conditions.  Cancers were reported for 110 workers, 51 of which were lung cancer, and 4 with multiple myeloma. 

    The McIntyre Powder aluminum prophylaxis program was a human experiment.  Documenting the health issues experienced by the affected workers and seeking answers for those workers and their surviving families remains the life work of the McIntyre Powder Project.  Many thanks to those who have contributed their stories. Your courage is making history and changing the future for those at risk for occupational disease.

  • McIntyre Powder Project presents to international scientific researchers at Keele 12 Meeting on Aluminum March 7, 2017

    On March 7, 2017, the McIntyre Powder Project and the Occupational Health Clinics for Ontario Workers, Inc. (OHCOW) will be presenting information about mine workers who were exposed to aluminum dust, to an international conference of scientific researchers of aluminum.  It is hoped that this meeting will result in research partnerships between OHCOW and scientists, to help determine if there are any associations between occupational aluminum dust exposure and health issues.   Our presentation abstract (summary) is below:

    PLATFORM 26 

    The McIntyre Powder Project: A retrospective study of the health effects of respirable aluminum dust in a cohort of Ontario miners 

    Martell, Janice1 ; Occupational Health Clinics for Ontario Workers, Inc. 

    1. Occupational Health Clinics for Ontario Workers, Inc. 

    Between 1943 and 1980, at least 20,000 miners were treated prophylactically with McIntyre Powder – a finely ground, respirable dust comprised of 85% aluminum oxide and 15% elemental aluminum. No other group has been exposed to aluminum in this form, intensity, duration, or by similar route of administration (an inhalable, airborne suspension). The only two clinical studies ever conducted on this specific group of workers both supported putative neurologic effects of McIntyre Powder exposure. Over an 18-month period, an informal voluntary registry of 322 exposed workers was compiled by the daughter of a McIntyre Powder-exposed miner – 65% of exposed workers had respiratory diagnoses or symptoms, and 33% had neurological disorders or symptoms. Based on these preliminary findings, a database of exposed mine workers is being compiled by the Occupational Health Clinics for Ontario Workers to investigate the causal relationship between McIntyre Powder exposure and adverse health outcomes.
