  1. Results also shown from fresh birch reference and previously reported values from samples from object 229 and the Oseberg ship. When available, the uncertainty is given in parenthesis as standard deviation. The * indicates that the value in the diluted solution was below the limit of quantification of the method, but above the limit of detection (LOD)
