Silver, copper, lead, zinc, and molybdenum were analyzed by ICP-AES and following a digestion of a multi acid (total digestion) solution. The laboratories analyzed the remaining elements by ICP-AES. In most instances, when the results of samples analyzed by this method exceeded the upper detection limits, the samples were not reanalyzed, but results were reported as being greater than the corresponding upper detection limit. However, values above ICP-AES detection limits were obtained for some samples using low-level assay methods consisting of a multi acid digestion and AA finish, with results reported in percent.
