“…Blood concentrations of Hg, Se, As and Cd, indicating recent exposure, differed between the Baltic Sea and Svalbard eider populations. In accordance with reported sediment concentrations of elements at the two locations (Vallius 2009;Grotti et al, 2013;Lu et al, 2013;Vallius 2015a), blood concentrations of Hg were significantly higher in Baltic eiders compared to Svalbard eiders. This is consistent with previous reports indicating that Hg levels in Baltic biota, such as in fish and blue mussels from Svalbard, Western Greenland, East Canada and Finland.…”

“…Sediment analysis from the Baltic Sea (Gulf of Finland) and Svalbard (Kongsfjorden) indicates that the concentrations of Cd and Hg are higher in the Baltic Sea compared to Svalbard, but for other toxic elements, sediment concentrations may be comparable between the two locations (Grotti et al, 2013;Lu et al, 2013;Vallius, 2009Vallius, , 2015a.…”

“…Contrary to Hg, blood concentrations of Cd, Se and As were greater in Svalbard compared to Baltic eiders. Reported sediment concentrations from relevant locations in the Baltic Sea and Svalbard might indicate that exposure levels to Cd are higher in the Baltic Sea (Vallius 2009;Grotti et al, 2013;Lu et al, 2013;Vallius 2015a).…”

We report blood and feather concentrations of elements in the Baltic Sea and Arctic population of common eiders (Somateria mollissima). The endangered Baltic Sea population of eiders was demonstrably affected by element pollution in the 1990s. While blood concentrations of Hg were higher in Baltic breeding eiders, blood Se, As and Cd concentrations were higher in Arctic eiders. Blood concentrations of Pb, Cr, Zn and Cu did not differ between the two populations. While blood Pb concentrations had declined in Baltic eiders since the 1990s, Hg concentrations had not declined, and were above concentrations associated with adverse oxidative effects in other bird species. Inconsistent with blood concentrations, feather concentrations suggested that Pb, Zn, and Cd exposure was higher in Baltic eiders, and that Hg exposure was higher in Arctic eiders. Our study thus emphasizes the need for comprehensive evaluation of toxic element status, covering the annual cycle of a species.

“…The issue of the quality of the sediments has grown in importance during the last years mainly due to the increased activities at sea, which are affecting the seafloor, and knowledge of the state of the sediments is then crucial. A similar sediment quality evaluation was already earlier published (Vallius 2015a) on offshore data from the Gulf of Finland which were obtained during the Finnish-Russian TRANSIT project during the years 2007 to 2010.…”

“…While the SAMAGOL study concentrated on the eastern Gulf of Finland the aim of the TRANSIT study was to investigate the offshore middle corridor from west to east through the entire Gulf of Finland. That data were mainly reported in a geochemistry study (Vallius 2012), but also in an assessment study on the northern Baltic Sea (Vallius 2014) as well as in a study on the quality of the offshore sediments in the Gulf of Finland (Vallius 2015a). …”

Our recent knowledge of the chemistry of the seafloor of the Baltic Sea has been gained during the last century only and most of it during the last three to four decades. When thinking about the start of the industrialization it seems unfortunately late. However, fortunately the seafloor archives all environmental changes in the sedimentary column like pages in a book and they can be later observed and interpreted. The Geological Survey of Finland has performed seabed geochemistry studies for decades. The first studies were performed onboard cruises of the old research vessel Aranda and later on the new Aranda as well as on the surveys on our own vessels Geola, Kaita, and Geomari. A great part of the work has been done as collaboration in international research programmes, but especially the Marine Ecogeological Patrol by the A. P. Karpinsky Russian Geological Research Institute has been of great importance for Gulf of Finland studies and as a trigger for later studies in the Gulf of Finland as well as the Baltic Sea.

Organic carbon with variable chemical composition sourced primarily from terrestrial and aquatic biogenic input has a significant impact on sediment heavy metal mobility. The present scientific view is unclear in deciphering the role of labile organic carbon in changing sediment heavy metal concentration. The present review critically assesses the impact of various forms of carbon on different geochemically bound heavy metal fractions and their monitoring. It is evident from the review that, the biochemical form of organic carbon (based on degradability and biopolymeric forms), carbon‐geochemical association, and density of organic carbon (light or heavy carbon fractions) plays an important role in determining the bioavailability and toxicity of metals for aquatic organisms. Besides the organic carbon, various sediment conditions that define the behavior of heavy metals include pH, redox condition, sulfide concentration, salinity, temperature, etc. Therefore, it is recommended that carbon relation with heavy metal mobility and stability should be included under long‐term sediment management plans to maintain the sediment quality of the river system.
