Copper, Zinc, Arsenic, Cadmium, Mercury, and Lead in Blue Mussels (Mytilus edulis) in the Bergen Harbor Area, Western Norway

Metal contamination in Portman Bay (Murcia, SE Spain) 15 years after the cessation of mining activities

“…In any case, the Cd and Pb concentrations in mussels from Portman Bay are the highest measured along the Iberian Mediterranean coast in 2005, except for the Pb concentrations found at Cartagena (8.68 mg kg -1 w.w.) (Benedicto, unpublished data). Overall, the metal concentrations recorded at Portman are also higher than the mean values obtained in previous studies carried out along the southern Mediterranean coast and North Atlantic coast of Spain (Besada et al 2002), the Mediterranean coast of France (RNO 2000), and coastal areas of western Norway (Airas et al 2004). Similar and even higher Cd and Hg concentrations than those found at Portman have been reported in mussels from harbour and industrial settings along the southern Adriatic and Ionic coasts of Italy .…”

“…(Benedicto, datos sin publicar). En general, las concentraciones de metales medidas en Portmán en 2005 son también mucho mayores que los valores medios obtenidos en estudios anteriores en la costas sur-mediterránea ) y noratlántica de España (Besada et al 2002), la costa mediterránea de Francia (RNO 2000), y en áreas costeras del oeste de Noruega (Airas et al 2004). Se han citado concentraciones de Cd y Hg similares, e incluso más elevadas, que las obtenidas en Portmán en mejillones de puertos y zonas industriales situadas en la costa sur adriática y jónica de Italia .…”

Fish Intake, Contaminants, and Human Health

“…Levels of n-3 Fatty Acids and Contaminants in Commonly Consumed Fish, Shellfish, and Other Foods* (cont) Based on data from US Department of Agriculture (USDA),121 Food and Drug Administration (FDA),110 Environmental Protection Agency,122 and other[103][104][105][106][107][108][109][111][112][113][114][115][116][117][118][119][120][123][124][125][126] sources.…”

Elevated mercury levels in a wintering population of common eiders ( Somateria mollissima ) in the northeastern United States

“…Mussels collected approximately 12 km away had a mean Hg concentration of 0.02 lg/g (ww) (Garron et al, 2005). Airas et al (2004) reported mean Hg concentrations of between 0.01 and 0.03 lg/g (ww) in mussels from Norway. Another study in Canada reported Hg concentrations in mussels ranging from 0.01 to 0.04 with a mean of 0.02 lg/g (ww) (Legrand et al, 2005).…”

“…This accumulation represents the portion of contaminants in the ecosystem that is biologically available to higher trophic level species (Leblanc et al, 2009). The blue mussel's sedentary behavior and ability to accumulate contaminants from the water column have led to its wide use as an indicator of aquatic ecosystem health (Julshamn and Grahl-Nielsen, 1996;Airas et al, 2004;Garron et al, 2005;Burger and Gochfeld, 2006). While there are currently no known studies that examine correlations between blood and prey item Hg in free-living eiders, understanding this dietary preference suggests that Hg levels in eider blood should be correlative with Hg levels found in blue mussels collected at the same location.…”
