The assessment of sources and sinks constitutes a logical step localized at the end of an analytical strategy. Prior to the quantification of sources and sinks, spatial and particularly time trends of the investigated elemental parameter are to be identified (Helmers, contribution in this book). Sources and sinks, are closely connected within biogeochemical cycles: The atmosphere constitutes a primary sink since aerosols possess a residence time of only several days (Buat-Ménard 1983). International exchange of Pt via the atmosphere is not considered here. In another view, the atmosphere acts as a diffuse source for Pt polluting soils as the secondary and permanent sink. Also freshwater as well as the seas are receiving Pt from diffuse (atmospheric input) or point sources (dumping) in the function of a primary sink. Anthropogenic input of metals into freshwater and seawater is then followed by e.g. scavenging generating polluted sediments as a secondary sink.
