abstract = {Human  activities,  such  as  agriculture  and  industrial,manufacturing,  have  supplied  contaminants  to  the  river,systems,  and  are  changing  their biogeochemical  propertities,and ecosystems. These human-induced impacts have put river,systems  under  great  pressure  in  the  recent  decade.  It  has,therefore  become  increasingly  important  to  evaluate  the,anthropogenic controls and quantitatively assess their relative,impacts  on  the  river  systems.  In  this  study,  we  explore  the,potential  of  the  Sr,  Nd,  and  Pb  isotope  systems  as  a,fingerprinting  tool  to  trace  anthropogenic  controls  on,historically heavily contaminated river Weser in Germany.,Sediment  samples  were  collected  along  the  river  Weser,and  its  tritutaries,  covering  areas  of  agricultural  land  and,industrial sites, and expanding to coastal areas of the North,Sea. Isotopic ratios of Sr, Nd, and Pb were measured on MC-,ICP-MS  (Multi-collector-Inductively  Coupled  Plasma-Mass,Spectrometry)  with  the  newly-developed  automated,prepFAST sample purification method [1]. The Sr, Nd and Pb,isotope results reported here are the first such dataset obtained,from the sediment of the river Weser. Using mixing models,,we  demonstrate  the  great  potential  of  the  Sr,  Nd  and  Pb,isotope systems as fingerprinting tools to identify the sources,of contaminants and to evaluate anthropogenic controls on the,load  of  contaminants  in  the  sediment.  Coupled  with,measurement of elemental compositions in the sediment and,the  principal  component  analysis,  we  further  provide  an,evaluation of  the  relative  contribution  of  various  sources  to,the  load  of  contaminants  in  the  river  Weser.  An  attempt  is,also made to quantify the flux of the river to the North Sea,,providing an insight into the contribution of the river system,to contaminants transported into the coastal zone.},
