Sažetak
Stream sediments from flysch-draining rivers Rižana, Dragonja, Mirna, Raša and Rječina, flowing to the North Adriatic Sea, have been studied by detailed mineralogical, chemical and geostatistical methods. Levels and sources of major and trace elements determined by ICP-MS method in sediment fraction <63 μ m were used as a data set for statistical analysis. Cluster analysis of Q-modality showed that according to geochemical composition of sediments Rižana forms a separate cluster. Raša, Dragonja and lower stretch of Mirna belong to the second cluster, while Rječina and upper stretch of Mirna belong to the third cluster. Sediments reflected anomalous concentrations of 20 elements, when using the same data set and two dimensional scatter box diagrams from program STATISTICA 6.0. Most anomalous values were found in Rižana and Rječina rivers, what can be of concern because they are used as sources of drinking water. Raša, Mirna and Dragonja present clean environments.
