OK, I am not anti Azomite. I just want everybody to be informed when they are using the Azomite. I think it is best to use some form of mask when you are applying the Azomite dust so you do not breathe it in. According to the Azomite's Mineral Analysis, the two top minerals making up Azomite are Silicon Dioxide at 65.85% and Alumina at 11.43%. I don't know breathing in Silicon Dioxide is harmful or not but I know that breathing in Alumina is very harmful as aluminum is said to be a neurotoxin. Other than that, if you inhale alumina (aluminum dioxide), you can "irritate the nose, throat, and lungs" and "repeated exposure can lead to lung damage" according to NJ Health Hazardous Substance Fact Sheet.
