Results and discussion

Any other information on results incl. tables

The Sr- baseline levels that are presented below were used for the construction of an environmental concentration distribution for Europe. It was decided, however, to exclude the countries that do not belong to the EU-27+Norway. The overall median in Europe (50th percentile of the generated log-logistic distribution) of background Sr is 76.0 mg Sr/kg dry wt.
