“…Both seasons for MTs, and the summer season for Cd statistically significantly (p<0.05) differ from the rest of the year, while Zn indices, although higher during summer, were not statistically significantly different from the rest of the year (p=0.2). Serafim et al (2002) reported that MT expression in gills of Cd-exposed mussels was significantly higher at higher temperature, while similar temperature dependent Cd accumulation was reported by Serra et al (1999). Greater Cd accumulation during the summer months was also observed in the study on Crassostrea virginica as a sentinel organism (Zaroogian, 1980).…”

“…The distribution of metals among the various organs seems to depend on the species and on the metals. Serra et al (1999) observed that the gills were the prefential organ for cadmium uptake in M. galloprovincialis. In this study, Cu and Cd concentration levels are higher in mussel tissues than in their shells and these results are in agreement with those obtained by Stanciu et al (2004).…”

Bioaccumulation of metals in black mussels (Mytilus galloprovincialis) in Cape Town Harbour, South Africa

Heavy metal concentrations in black mussels (Mytilus galloprovincialis) collected from Cape Town Harbour were determined using energy dispersive X-ray fluorescence (EDXRF) and inductively coupled plasma-mass spectrometry (ICP-MS). EDXRF showed that tissue portions of the mussels contained K, Ca, Fe, Cu, Zn, Si, Sr, Al and Au, while the shell portion contained K, Ca, Fe, Cr, Zn, Si and Sr. In addition to these metals, EDXRF also revealed the presence of Al in the shells of the largest mussels. Highest concentrations of Cu and Zn were recorded in the tissues of the smallest mussels. Due to poorer detection limits of EDXRF, ultra-trace elements (Mn, Pb, As, Hg, V, Cr, Sn, Cd, Ni and Co) were determined in mussels using ICP-MS. The average metal concentrations found in the mussels are as follows; Pb (7.30 ± 0.67), Cd (1.98 ± 0.13), Hg (4.92 ± 0.60), As (6.94 ± 0.04), Sn (2.63 ± 0.13), Ni (1.88 ± 0.05), Cr (3.54 ± 0.05), V (4.17 ± 0.23), Co (0.74 ± 0.01) and Mn (35.20 ± 1.46). ANOVAs, Pearson correlation and principal component analysis (PCA) were employed in data analysis. The order of the abundance of metals in the mussels isThe average metal concentrations found in the mussels were higher than the permissible Food and Agriculture Organization (FAO) limits and other international guidelines.

“…MT induction has been included in international marine monitoring programmes such as OSPAR JAMP (Joint Assessment and Monitoring Programme) (Stagg 1998) and MED POL (Mediterranean Pollution Biomonitoring Programme) (UNEP/RAMOGE 1999) as a biomarker of exposure to assess metal pollution in aquatic ecosystems. Both metal and MT levels have been shown to vary depending on body weight, gender, reproductive stage, size, season and water temperature (Hylland et al 1992, Roesijadi 1994, Olsson et al 1995, 1996, Bordin et al 1997, Serra et al 1999, Serafim et al 2002. Consequently, these natural fluctuations have strong implications for the use of MTs as a biomarker for the determination of metal pollution (Olsson et al 1998).…”

Application of two SH-based methods for metallothionein determination in mussels and intercalibration of the spectrophotometric method: laboratory and field studies in the Mediterranean Sea

et al. 2005

Metallothionein (MT) induction is widely used as a biomarker of exposure to metals in mussels. The aims of the present work were first to compare the suitability of spectrophotometry and differential pulse polarography (DPP) for MT detection in mussels exposed to 200 ppb cadmium for 9 days in a laboratory experiment and in mussels sampled in different seasons from expected pollution gradients along the Mediterranean Sea; second, to intercalibrate the widely used spectrophotometric method using mussels from Saronikos Gulf. In the intercalibration of the spectrophotometric method, similar results (p>0.05) were obtained by two different research teams indicating a good reproducibility of the technique. However, polarographic and spectrophotometric methods gave significantly (p<0.05) different results in laboratory and field studies. In the laboratory experiment, MT values detected with DPP were nine times higher than with spectrophotometry. The results obtained by the two methods were significantly correlated. Both methods could discriminate between control and exposed mussels. In field studies, MT values obtained by DPP were 34-38-fold higher than with spectrophotometry, and MT concentrations measured by both methods were not correlated. This discrepancy could be due to several factors, including the low levels of bioavailable metals in the studied areas and the possibility that the different methods can measure MT isoforms differentially. Further work is needed to decipher the functions of MT isoforms in mussels. This information is relevant for the application of MT as a biomarker in biomonitoring programmes.
