C, N and their Stable Isotopes in Suspended and Sedimented Matter from the PO Estuary (Italy)

C, N and their Stable Isotopes in Suspended and Sedimented Matter from the PO Estuary (Italy)

C and N content, C/N (atomic) ratio, and C and N isotopic composition (δ13C and δ15N) were determined on suspended particulate matter and sediment samples obtained from riverine, estuarine and marine environments in two cruises (September 1995 and March 1996) in the Po estuary (Italy). Isotopic trac...

Zusammenfassung:C and N content, C/N (atomic) ratio, and C and N isotopic composition (δ13C and δ15N) were determined on suspended particulate matter and sediment samples obtained from riverine, estuarine and marine environments in two cruises (September 1995 and March 1996) in the Po estuary (Italy). Isotopic tracers of C and N, reported for the first time for this environment, gave information on sources of organic matter and their distribution. An end-member mixing model based on δ13C values was applied to estimate the relative importance of riverine and marine sources of organic matter in suspended particulate matter and sediments.[PUBLICATION ABSTRACT]
