“…Thus, biological features of mussels may give vital information about water pollution. Several species, including mussels, have been used as indicators of life exposure, based on the assumption that metal contents in soft tissues of mussels are related to metal concentrations in the corresponding environment (Pempkowiak et al 1999;Bryan and Langston 1992;Cossa 1989;Abisil et al 1996;Hummel et al 1997). The soft tissues accumulate metals more efficiently than the shells, although shells may also give information about pollution levels in the environment.…”

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.

“…Observations of the interactions between metals and DOC are, however, conflicting. In some studies, a reduction in metal toxicity was found in the presence of natural organic matter, which was largely ascribed to the complexation of organic ligands with metals and, thus, a reduction in the concentration of available free ionic metals (Campbell 1995, Absil et al 1996. Choi et al (1998) observed a decrease in MeHg uptake by the Sacramento blackfish Orthodon microlepidotus, as well as in the MeHg level in the gills, with increasing DOC concentrations.…”

The bioavailability and toxicity of mercury to aquatic organisms are greatly dependent on its chemical species, such as inorganic and methylated mercury. We examined the influences of various physico-chemical parameters [metal concentration, salinity, dissolved organic carbon (DOC) and colloidal organic carbon (COC) on the bioavailability of inorganic mercury (Hg(II)] and monomethylmercury (MeHg) to the green mussel Perna viridis. The uptake rate constant of MeHg was about 8.5x higher than that of Hg(II). The uptake increased by 75% for Hg(II) and 117% for MeHg with decreasing salinity from 30 psu to 15 psu. Biogenic DOC derived from diatom decomposition decreased the uptake of Hg(II), consistent with the results of DOC originating from natural seawater. In contrast, the uptake of Hg(II) was enhanced considerably in the presence of humic acid. The bioavailability of MeHg was only weakly influenced by differences in DOC quality or quantity, but it was significantly decreased by estuarine DOC. The influence of COC on Hg bioavailability was also dependent on the colloidal structural properties and the colloid-metal complexation. Binding with colloidal nanoparticles increased the uptake of Hg(II) by 3.3 to 7.3 times compared to low molecular weight-complexed Hg, but decreased the uptake of MeHg by 42 to 73%. For both Hg(II) and MeHg, the uptake of the 9 d aged radiolabeled metals was lower than the uptake of the 2 d aged radiolabeled forms. Our study suggests that various mechanisms, such as facilitated transport and direct colloidal ingestion, are involved in the uptake of Hg(II) and MeHg under different dissolved and colloidal organic carbon conditions. COC and DOC need to be separately considered, given their different influences on mercury uptake.

“…Such species have limited contact with pore waters outside their tubes. Some bivalve species (e.g., the cockle Cerastoderma edule) inhabit sediments and feed from the overlying water (Absil et al 1996). Other bivalve species (e.g., the clam Macoma balthica) are facultative feeders and can change their food source if required (Stecko and Bendell-Young 2000).…”

Uncertainties in sediment quality assessments are discussed in five categories: (1) sediment sampling, transport and storage; (2) sediment chemistry; (3) ecotoxicology; (4) benthic community structure; and (5) data uncertainties and QA/QC. Three major exposure routes are considered: whole sediments, and waters in sediment pores and at the sediment-water interface. If these uncertainties are not recognized and addressed in the assessment process, then erroneous conclusions may result. Recommendations are provided for addressing the identified uncertainties in each of the key areas. The purpose of this paper is to improve the reporting of sediment quality assessments.
