“…39,40 In the lagoon, mussels are generally exposed on a chronic basis to a complex mixture of contaminants, with the result being an acclimatization of the organism to severe environmental conditions through the activation of compensatory mechanisms. 13 Moreover, the biological responses to the presence of xenobiotics could be affected both by genetic and physiology variability of the organism (size, age, growth rate).…”

The levels of tributyltin (TBT) and dibutyltin (DBT) compounds were measured by gas chromatography ion-trap mass spectrometry (GC-MS/MS) in natural and cultured mussels (Mytilus galloprovincialis) from the northern Adriatic Sea in spring 2003. The highest (725 ng g −1 dry weight) and lowest levels (198 ng g −1 dry weight) of butyltins (TBT + DBT) were found in native mussels from the Lagoon of Venice, with the higher values being detected in specimens collected next to a dockyard and the lower values in specimens from a location characterized by strong water exchanges between the lagoon and the Adriatic Sea. The two cultured samples exhibited intermediate concentrations, with marine harvested samples being more contaminated than those from the lagoon.Concentrations of TBT were higher than those of DBT for several reasons: the limited capability of bivalves to metabolize TBT and their ability to accumulate it (with recent input of TBT into the environment as TBT-based anti-fouling paints being the most important contributor of organotin contamination in our study area); and higher lipophilicity of TBT than DBT. In order to find correlations between organotin pollution and the state of nourishment of the mussels, the condition index was also evaluated as the mass ratio of meat dry weight to shell dry weight. There was no correlation between condition index and butyltin concentrations. These results indicate that condition index could not give information about stress conditions, as the contamination level is probably too low to cause significant reductions in mussel growth.

“…Biomarkers that could measure exposure and provide a reliable indication of toxic effect can be very useful for assessing the environmental impact of pollutants in the field (Walker 1995). Mussels, as sessile, filter feeding organisms have been used in the marine environment as biomonitors of trace metals and can also be used in the assessment of sub-lethal biological effects of pollution (Nasci et al 1998). Mytilus galloprovincialis has been used extensively to evaluate the accumulation of organic pollutants and trace metals (Da Ros et al 2000).…”

The aim of this study was to identify possible relationships between biochemical- superoxide dismutase (SOD), glutathione peroxidase (GPx), thiobarbituric acid reactive substances (TBARS) of mussels (Mytilus galloprovincialis) and chemical (Hg, Cd, Pb, Cr, Cu, Zn, Mn and Fe) contaminants from relatively clean area (Middle Bay) and heavily polluted area (Inner Bay) of the Izmir Bay. Sampling of mussels was performed in the beginning of May 2004. Mussel digestive glands have been used for biochemical assays. Trace metal content was determined by atomic absorption spectrophotometer using standard procedures. Metal contents in mussels collected at polluted site increased compared to the middle part of the bay. While there was a positive correlation between metals and SOD enzyme activity, there was a negative correlation between metals and GPx enzyme activity. An increase was observed in SOD enzyme activity and a decrease of GPx enzyme activity at the inner part of the bay.

“…This is slightly higher than the mean concentrations for molluscs in the central (51 ng g À1 w.w.) and the northern/southern (46 ng g À1 w.w.) parts of the Lagoon as measured between 1995 and 2002 (Miniero et al, 2006). Mean THg concentration in M. galloprovincialis collected in 1995-1996 in the contaminated canals of Venice and Porto Marghera was 98 ± 24 ng g À1 w.w. (Nasci et al, 1998). Mean THg and MMHg concentrations in mussels (M. galloprovincialis) collected in 2000 from three unspecified sites in the Lagoon of Venice were 353 and 138 ng g À1 w.w. (Bloom et al, 2004a), which seems to be exceptionally high.…”
