Carbon composition in an endangered meridional peat bog. Ribetehilo lagoon (Doñana national park; SW-Spain)
Sediment cores encompass information about past environmental changes, fire history and conditions of organic carbon deposition. The information provided is valuable for a range of research fields such as; global climate change, pollution assessment and control, etc. (González-Vila et al., 2003). During the last 30 years, a varied array of modern analytical techniques has been developed to assess the molecular composition of sedimentary organic carbon (OC) (Rothwell and Rack, 2006). In this work the modification in the down-core molecular composition of a 85 cm peat bog from the Ribetehilo lagoon (Doñana National Park; SW-Spain 37° 7'30.81>N; 6°37'50.19>O) is studied. In less than 50 years, the area occupied by peat bogs in the Gulf of Cádiz has been reduced drastically by more than 90% (Sousa and García Murillo, 1999). Therefore, this peat bog may well be considered as relict and one of the last and more Meridional still in existence. For this work, 5 samples taken at different depths were analysed in detail (0-10, 25-30, 45-50, 65-70 and 80-85 cm) using analytical pyrolysis (Py-GC/MS) and ultra-high resolution mass spectrometry (ESI-FT-ICR/MS), the latter one was used with humic extracts because solubility is required. The detected compounds were grouped into 6 main biogenic families; lipids, unspecific aromatic compounds, polyphenols, protein, carbohydrates and condensed compounds.
