Recent study follows 2020 research that linked exposure to neurological disorders among Ontario miners
The medical records of Ontario miners exposed to McIntyre Powder over the years are giving up more information about the long term impact of aluminum dust on their health.
A new study published in the American Journal of Industrial Medicine finds a link between occupational exposure to McIntyre Powder and cardiovascular disease.
McIntyre Powder was a fine dust containing aluminum developed in Timmins that was dispersed in the air before each shift and miners told to breathe it in, as a method to coat their lungs and prevent silicosis.
It was licensed for use in mines around the world including in South America and western Australia and was used between the mid-1940s and 1979.
