Geochemical characterization and environmental status of Makirina Bay sediments (northern Dalmatia, Republic of Croatia)

This research focuses on determination of the mineralogical composition, geochemical characteristics and evaluationof pollution status of the Makirina Bay sediments. Calculated enrichment factor (EF) values show no enrichment ( Cd > Pb > Ni > Zn > Cu > As. Principal component analysis (PCA) and correlation analysis confirmed the PTE distribution depends mainly on thegeogenic mineral components and anthropogenic activities in the areas surrounding the bay. Calculated transfer factor(TF) values from sediment to seagrass Cymodocea nodosa (C. nodosa) were < 1, showing that despite the results of thesequential extraction procedure, PTE transfer from sediment to roots was not effective.
