Relazioni tra contenuto di materia organica, carbonio organico e granulometria nei sedimenti di aree di transizione

To describe the geochemical features of the sediments in nine sicilian coastal lakes, 78 samples of surface sediments were collected in July 2005. Analyses of Nitrogen, Total Organic Carbon, Organic Matter, Carbonates and Grainsize were performed. A better correlation between the Organic Matter, evaluated through the Sequential-LOI, and TOC was found at 350 °C, rather than at 450 °C. Statistical analysis confirmed the similarities of the trends of TOC and LOI350 in the samples pooled according to the dominant grainsize, with the highest values associated to the medium sand fraction. The differences among the median values of the groups were significant (ANOVA, Kruskal-Wallis; P<0.001). The …

First assessment of total organic carbon/macrofauna relation in Sicilian coastal lagoons

Sediment characteristics (Total organic carbon, C/N ratio, carbonates, grain size) and macrofaunal assemblages were studied in Sum- mer 2005 in 9 coastal lagoons of eastern Sicily (Italy) belonging to 3 study areas (Capo Peloro, Marinello and Vendicari). The diffe- rent ecosystems were selected upon their differences in geographical position, size, depth, water exchange, anthropic impact and expec- ted organic matter loading. The aim of this study was to explore the relationship between the Total organic carbon (TOC) content of se- diment and macrofaunal assemblages characteristics, as indicated by the Study Group on Benthic Indicators of IOC/UNESCO (http: //ioc.unesco.org/benthicindicators…
