Intercomparison of methods for the determination of mercury deposition to convention waters. Report prepared for the Paris commission

In this report, results from the intercomparison of collection and analytical methods for the determination of atmospheric mercury deposition to European marginal seas, are given. The intercomparison exercise consisted of four separate parts, to be able to separate influences from the methods of collection from effects assocaited with the analytical techniques. Six laboratories reported data in the analytical part of the intercomparison exercise, in which determined mercury levels in two precipitation samples were compared
