The Material Safety Data Sheet (MSDS) on mercury says "Skin absorption is a significant route of potential over-exposure to Mercury..." It's not the principle route of entry. Inhalation of mercury vapour, which is given off at room temperature, is the principle means. > I don't know, not about to try it, but I > think it would just come out the other end if you > ate it. Oral ingestion (according to the MSDS) is said not to be a significant route of occupational over-exposure, but if ingested it does cause severe gastro-intestinal damage as well as kidney damage. Glad you're not going to try eating any. > Where is mercury found? In rocks. (Specifically > bauxite). Bauxite is the principle ore of Aluminum. If there's any Mercury in Bauxite it's there in trace amounts as an impurity. Cinnabar is the principle ore of Mercury. Cinnabar's a mineral, Mercury Sulphide. 73 - Ken _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
