- It's true that some of the zinc would dissolve in stomach acid,
- however most of the compressed tablet would break up in the intestine
- after the acid had been neutralized. On the other hand I checked some
- vitamin books on zinc and found that it is an inhalation hazard. A
- single oral dose of 200 milligrams of zinc causes toxicity symptoms
- (some diabetics receive doses of 1 gram of chromium per day as a
- treatment); so chronic doses of zinc dust would be very low when
- toxicity symptoms occur. In general, maximum safe doses of inhalation
- hazards tend to be quite low, anyway.
