heavy metals (cadmium, copper, lead and mercury) in common eiders (somateria mollissima) from an examination of 50 danish common eiders, the liver and kidney content of cadmium, copper, lead and mercury was determined. eiders were chosen for analysis, because this species feed almost exclusively on the common mussel (mytilus edulis), which is known to accumulate heavy metals. the concentrations recorded of cadmium, copper, and mercury were lower than what is usually regarded as toxic for birds, except for one eider which carried more than 2000 mg copper/kg liver tissue (dry weight). o ...19836674934
a broad cocktail of environmental pollutants found in eggs of three seabird species from remote colonies in norway.eggs of 3 seabird species, common eider (somateria mollisima), european shag (phalacrocorax aristotelis aristotelis), and european herring gull (larus argentatus), were surveyed for a broad range of legacy and emerging pollutants to assess chemical mixture exposure profiles of seabirds from the norwegian marine environment. in total, 201 chemical substances were targeted for analysis ranging from metals, organotin compounds, polycyclic aromatic hydrocarbons (pahs), polychlorinated biphenyls (pcb ...201525728907
persistent organic pollutant levels and the importance of source proximity in baltic and svalbard breeding common eiders.the distance to sources and the long-range transport potential of persistent organic pollutants (pops) are important in understanding the impact of anthropogenic pollution on natural seabird populations. the present study documented blood concentrations of pops in the baltic sea (tvärminne, finland) population of common eiders (somateria mollissima) in 2009 and in 2011 and compared the concentrations with the presumably less exposed arctic population in svalbard (kongsfjorden, norway). the balti ...201626553455
