Translocation within the body is primarily in the blood plasma as silver chloride or silver albuminate (MRI 1975). About 10% of ingested silver is absorbed but only 4% retained in the tissues (Klein 1978). The mean silver intake rate from the diet is estimated at 88 µg/day (Kehoe et al. 1940). As indicated from the absorption studies mentioned above, silver is found in organs and areas of the body remote from the site of absorption, so translocation must occur. If the silver is introduced to the lungs by inhalation, some silver is cleared by the cilia and swallowed but most is dissolved and removed in the blood (Phalen and Morrow 1973).
