60 samples were analyzed by the following methods and digestions: ICP after HCl:HNO3 (3:1) acid digestion and AA after HCl:HNO3 (3:1) acid digestion. Some results for bismuth are below the lower limit of 1 due to that some samples may have been run by aqua regia with a hydride method that resulted in a lower limit of 0.2 and actual results between 0.2 and 1.
