The Canadian Gov. silver site: http://www.env.gov.bc.ca/epd/cpr/criteria/awqcfs.html states basically that "solver ions are 300 times more effective then silver chloride (if you salt water) and 15,000 times more effective then silver sulphide. The chance of using water with sulphide in it is small but the point is that other silver compounds may be just as non-effective! As I always stress, you must know what you start with, to get an effective form of silver for delivery to your body.
<snip>silver is one of the most toxic of the heavy metals to freshwater micro-organisms. <snip> The effect of speciation on the acute and chronic toxicity of silver was compared using the fathead minnow as the test organism. Silver sulfide, silver thiosulfate and silver chloride were compared to the silver ion, added as silver nitrate. The tests were flow-through in soft water at 25°C. Silver chloride was found to be 300 times less toxic, silver sulfide was 15,000 times less toxic, and silver thiosulfate was 17,500 times less toxic than silver nitrate. Most existing silver criteria, objectives or regulated amounts are not based on the free ionic monovalent ion, which is acutely toxic to aquatic life. Instead they are based on total silver which includes the metal, complexes and precipitates, all of which are very much less toxic than the monovalent ion. </snip> [email protected] -- The silver-list is a moderated forum for discussion of colloidal silver.
