The trace metals accumulation in marine organisms of the southeastern Adriatic coast, Montenegro

The concentration and accumulation of trace metals (Co, Ni, As, Cd, Pb and
Hg) were measured in sea water, sediments and marine organisms in the
coastline of the Montenegro. The obtained results of trace metals in seagrass
and mussels were compared with those found in the water column and sediment.
Sampling was performed in the fall of 2005 at five locations in the
Montenegrin coastline, Sveta Stasija, Herceg Novi, Zanjice, Budva and Bar,
which present different levels and sources of human impact. The heavy metals
analyses in seawater, sediment, P. oceanica and M. galloprovincialis
identified the harbor of Bar as the most Hg-contaminated site, Zanjice as the
most As contaminated and Sveta Stasija as the most Pb-contaminated areas of
the Montenegrin coastal area. This study showed that P. oceanica may have a
greater bioaccumulation capacity than M. galloprovincialis for the considered
metals, except for As and Hg, and both organisms may reflect contamination in
the water column and in the sediment. For the first time, seagrass P.
oceanica and M. galloprovincialis were employed as metal bioindicators for
the southeastern Adriatic. The results of this study could serve as a
baseline in the future for the assessment of anthropogenic effects in this
marine ecosystem.
