“…In fact, in the Gulf of Trieste, Cr mostly originates from the heavy mineral fraction that in turn derives from the presence of flysh (chromites and Crbearing spinels; Lenaz et al 1996). Giani et al (1994) reported similar conclusions in an area influenced by the Po River, where the main fraction of Cr was found in the residual phase (83-95%). The significative correlation found with Al (r=0.761, p≤0.05) confirms that Cr distribution in the Gulf of Trieste is prevalently controlled by the mineralogy itself.…”

“…The strong correlation with TOC suggests a possible anthropic origin of the element probably through the complexation by organic chelating molecules and/or the association by absorption to fine particles. The low correlation with Al could indicate that a part of the Pb is bound to the more mobilizable geochemical fractions as reported in Giani et al (1994).…”

A set of ten heavy metals (Al, As, Cd, Cr, Cu, Hg, Ni, Pb, V, and Zn) was investigated in surface sediments (0-5 cm) collected in 21 sites of the Gulf of Trieste, Northern Adriatic Sea (Italy). The aim of this work was to obtain a preliminary assessment about the levels and spatial distribution of these selected elements. Ancillary parameters such as grain size, total organic carbon, and total nitrogen were also determined. The enrichment factor was calculated to discriminate if a natural condition or a status of anthropogenic contamination occurs. In addition, a set of sediment quality guidelines, mean effect low range and effect medium range quotients, was also applied in order to predict the probability of adverse biological effects on the benthic community.

“…-1 for Zn. All these data suggest that heavy metal mass fractions measured in the Plomin Bay sediments kept within in the ranges reported for other relatively unpolluted localities of the Northern Adriatic Sea (5,7,(13)(14)(15)(16)(17)(18)(19).…”

“…Heavy metal mass fractions in sediment samples from the investigated area exhibited values lower or equal to those reported for relatively unpolluted regions of the Adriatic Sea (5,(13)(14)(15)(16)(17)(18)(19). Granulometric and chemical composition of the dredged material was highly homogeneous, exhibiting no signifi cant difference between layers.…”

“…Disposal of dredged material to the sea bottom is a common route for the transport of contaminants into the open sea (5,6). Our study of the granulometric, chemical, and leaching properties of the Plomin Bay sediment was undertaken in order to assess a possible infl uence of the power plant on the quality of sediments as well as the risk of heavy metal remobilisation from dredged material into the water column and further penetration into the food chain.…”

Granulometric, chemical, and leaching properties of sediments dredged in the Plomin Bay (Northern Adriatic Sea, Croatia) were investigated in order to asses the risk of remobilisation of heavy metals into the water column. In total 65 samples from 65 sampling sites were taken from different sediment depths within the bay. Analysis of variance confi rmed the homogeneity of granulometric and elemental composition of the investigated sediment throughout its volume. Granulometric analysis showed that all samples corresponded to a pelitic fraction (<0.063 mm). Bulk elemental mass fractions in the sediments were similar to literature data on relatively unpolluted areas of the Adriatic Sea. High sedimentation rate caused by constant infl ow of material from the Boljunčica River drainage may be responsible for low levels of heavy metals and negligible infl uence of fl y and bottom ash from a nearby disposal site on the chemical composition of the sediments. In contact with sea water only 0.29 mg kg -1 of V, 0.04 mg kg -1 of Cr, 0.07 mg kg -1 of Ni, 0.33 mg kg -1 of Cu, 0.67 mg kg -1 of Zn and 0.06 mg kg -1 of Pb could be remobilised from sediment material into the water column. However, these values increased three to ten times in case of leaching with organic acids.
