Determination of trace metals in Mytilus galloprovincialis along the Boka Kotorska Bay, Montenegrin coast.

The concentrations of six trace metals, cadmium (Cd), copper (Cu), chromium (Cr), lead (Pb), zinc (Zn) and mercury (Hg) were determined in the soft tissues of the mussel Mytilus galloprovincialis and bottom sediments collected from the coastal area of Boka Kotorska Bay (Montenegrin coast). The mussels and sediment samples were collected at three sites along the Boka Kotorska Bay from the autumn of 2014 to the winter of 2016. The concentrations (mg/kg dw) of these metals in the mussel samples ranged from 1.01 to 2.87 for Cd, 6.08 to 13.2 for Cu, 1.37 to 3.55 for Pb, 85.6 to 241 for Zn, 0.72 to 4.05 for Cr and 0.098 to 0.269 for Hg. The concentrations (mg/kg dw) of these metals in the sediment samples ranged from 0.16 to 0.39 for Cd, 4.32 to 48.2 for Cu, 7.02 to 49.8 for Pb, 22.0 to 158 for Zn, 93.1 to 317 for Cr and 0.035 to 0.497 for Hg. The metal content in the mussel samples and the metal content in the sediment collected from three locations over four different seasons were analyzed using the Pearson correlation coefficient (r) and cluster analysis (CA). A correlation between the metal levels found in the mussel soft tissues with those found in the sediments, for both 2014 and 2015, were established. The metal pollution indexes (MPI) for the sediment and mussels were compared, indicating that the most polluted sediment was at the location Institute of Marine Biology Kotor (IBMK) and the most polluted mussels were sampled from the Zanjice location.

Human exposure to trace elements via consumption of mussels Mytilus galloprovincialis from Boka Kotorska Bay, Montenegro.

In order to assess human health risks via consumption of potentially toxic mussels, the concentrations of Al, Ba, Cd, Co, Cr, Cu, Fe, Li, Mn, Ni, Pb, Sr, Zn and Hg were studied in Mytilus galloprovincialis collected from the coastal area of Montenegro. By two approaches for the human health risk assessment (HHRA), considering oral reference doses by the United States Environmental Protection Agency (US EPA) and provisional tolerable intakes by the Joint FAO/WHO Expert Committee on Food Additives (JECFA), it has been revealed that despite the fact that trace element levels do not exceed the defined limits for mussels, they can be limiting factors for the mussel consumption. Specifically, it was noticed that the levels of Co, Pb, Cd and Li could be the limiting factors for the consumption of mussels from this coastal area. Al and Li data obtained in this study are especially important since these two elements have not been previously studied in M. galloprovincialis. Furthermore, taking into account the significant differences in concentrations of elements in different seasons, the study confirmed the starting assumption that in the calculations for the HHRA the average concentrations of elements in samples taken in different seasons during a longer period should be used.

Human exposure to trace metals and possible public health risks via consumption of mussels Mytilus galloprovincialis from the Adriatic coastal area.

Considering the growing concern due to different levels of anthropogenic loadings, the main purpose of this study was to identify the levels of trace metals (Fe, Mn, Cu, Zn, Co, Ni, Cd, Pb and Hg) in the mussels Mytilus galloprovincialis sampled along the marine coast of Boka Kotorska Bay, Montenegro. In comparison with the permissible limits set by the EU and the US FDA, all trace metal concentrations found in the mussels from the coastal area of Boka Kotorska Bay were lower than the prescribed limits. Generally, the trace metal concentrations found in Montenegrin mussels are within the range of trace metal concentrations determined in low to moderately polluted Adriatic areas. Based on these and other available literature data published by other authors for Adriatic region, the public health risks associated with the consumption of mussels in relation to reported trace metal concentrations were evaluated. In terms of the obtained trace metals concentrations in mussels and the provisional tolerable weekly intake prescribed by the JECFA and oral reference doses by the US EPA, the Pb and Cd concentrations and the Co and Cd concentrations were recognized as the limiting factor for the consumption of mussels from some Adriatic areas, respectively.
