Thank you for sharing the article. In the early 90's I worked in the Advanced Ceramics R&D lab at Dow Chemical. I worked extensively with metal powers, mostly aluminum. We developed new materials/processes for making new materials the one I worked on was called self propagating high temperature synthesis; a combustion process using nitrogen as the oxidant.
At the time and since I've been concerned that I would suffer the affects of all of the aluminum powder that I certainly inhaled and assumed Alzheimer's disease would affect me.
It was interesting to read about the affects of aluminum on brain tissue RNA.
Thank you!
