Topological maps of Kohonen self-organization (som) applied to the study of sediments contaminated with PBDEs support for climate extremes risk assessment /
Riverine sediments, collected during 2012 from ten sites in a mixed land use region of the Serbian were analysed for seven emergent PBDE congeners. All PBDEs were detected in sediments with the total concentrations range from 0.52 µg/kg (Ratno Ostrvo) to 31.19 µg/kg (Neštin) with mean levels of 8.08...

| Tartalmi kivonat: | Riverine sediments, collected during 2012 from ten sites in a mixed land use region of the Serbian were analysed for seven emergent PBDE congeners. All PBDEs were detected in sediments with the total concentrations range from 0.52 µg/kg (Ratno Ostrvo) to 31.19 µg/kg (Neštin) with mean levels of 8.08 µg/kg and median of 3.14 µg/kg. The classification of data by Kohonen's self-organizing maps (SOM) allowed understanding and visualizing the spatial distribution of samples. Principal component analysis (PCA) was used for validating the obtained results. Correlations and relationships between the samples and the variables can be easily visualized using the viewing of SOM planes of components. The results have highlighted the dependencies between the different PBDEs and the classification of studied sediments into three classes into function of ten stations coring and their pollution levels. |
