For your information, silver is considered a hazardous constiuent per RCRA and has the same regulatory limit as chromium.
In other words any waste containing 5.0 mg/L or more would be considered a hazardous waste per RCRA.
No, household hazardous waste is not regulated (and sewage is covered by the Clean Water Act), but I bring this up to illustrate that high levels of it may not be very good for you. I would have to go back to the early Federal Registers to determine why the feds though it necessary to list silver as a hazardous constiuent.
BTW, there are only eight RCRA metals; arsenic, barium, cadmium, chromium, lead, mercury, selenium and silver.
Silver's keeping some pretty nasty company.
You might want to keep this in mind before you go dosing yourself with it.
