“…As a result, in the near-shore gravelly and sandy deposits the concentration of Hg are as high as in the muddy sediments. Also in this study the mercury anomaly outside Kymijoki River can be confirmed (Fig.5), even though Hg concentrations have been found to have decreased considerably during the last decades (Vallius, 2014). The highest surface concentration observed (0.58 mg/kg) is from one of the bays within one of Kymijoki outlets.…”

“…All these data were combined into a common database of heavy metals, and longitudinal geochemical profiles and geochemical maps were constructed. This study is a synthesis and further interpretation of the geochemistry of heavy metals in Gulf of Finland sediments after the studies by Kravtsov and Emelyanov (1997), Vallius (2014), and a study by Vallius (2012).…”

“…Data on high concentrations of trace elements in the sediments of the Neva Bay have also been published by VSEGEI (VSEGEI 2010;Info Bull. 2013, 2014. Simultaneously with the Russian research in the Gulf of Finland, such work was also carried out by Finnish scientists (Vallius, Leivuori 1999;Vallius, 2012).…”

“…In these studies it was found out that during years 2005-2007 the near-bottom water in the Neva Bay was highly enriched in Zn and Pb, while their concentrations in years 2008-2010 were extremely low (Shkatov et al 2011). The changes in time of the concentrations of the mentioned microelements were studied also by Vallius (2014).…”

The Gulf of Finland has during the last centuries been loaded with heavy metals of anthropogenic origin. Work with mapping of the chemistry of the sediments have been done in all surrounding countries during several decades, first in the Soviet Union and later in Russia and similarly in Finland. More recent sediment chemistry data from the last two decades was in this study combined into sediment chemistry maps added with some data from the commercial Nord Stream project. The result shows that zinc, copper and chromium are enriched in the eastern part of the Gulf of Finland, while mercury, cadmium and lead are showing the highest concentrations in the north-eastern part of the gulf.

“…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.
