Thanks. I am going to revise what I say about silver and EIS, in light of this info. There is such good evidence FOR silver that it is not necessary to use an inaccurate or misleading statement in its defense. paula ----- Original Message ----- From: Matthew McCann PE
Hi, Sol. According to the periodic table published by Sargent-Welch Scientific Company, the density of silver is 10.5 grams per cubic centimeter (water has a density of one gram per cubic centimeter.) Even water is toxic in amounts large enough to drown in. We cannot live without iron, copper, zinc and manganese. Their respective densities are: 7.86, 8.96, 7.14 and 7.43 grams per cubic centimeter. So they are all heavy metals according to the definition you mention. Best regards, Matthew
