Mercury in archived samples

The re-measurement of mercury (Hg) concentrations in archived environmental samples (soils, peats) after several years of storage indicated that there is no statistical difference between new measurements and original data. As a result, archived samples can be used to evaluate historical soil mercury contamination.
