“…In this article, authors compare ABIORAS (Kaliningrad) data with the data of the Geological Survey of Finland (GTK) (Fig. 2), which methods have been reported earlier (Vallius, 2012). There was a satisfying agreement between the results of the two institutes (Fig.…”

“…Verta et al (2009) reported that more than 30 tons of mercury was emitted to the River Kymijoki between the 1940'ies and 1971, which has been shown in many studies from the Gulf of Finland (Kokko, Turunen 1988;Vallius 2012). The concentrations of Hg in the sediments of the contaminated north-eastern part of the Gulf of Finland are very high.…”

“…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).…”

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.

“…The cooperation with the Russian and Ukrainian scientific crews worked very well, a reason why this Finnish-Russian cooperation continued until the MEP programme ended in 1995. The results of GTK work on the first MEP cruise have been reported in a couple of different papers (Vallius, Lehto 1998;Vallius 1999;Vallius 1999b;Vallius 2012;Vallius, Leivuori 1999;Vallius, Leivuori 2003).…”

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.

Survival rate, frequency of malformed embryos, and antioxidant defense system responses in the benthic amphipod Gmelinoides fasciatus from the Baltic Sea were measured to examine the effects of toxic sediments, and to assess the usefulness of these endpoints in sediment toxicity biotesting. A highly contaminated sediment sample from the Baltic Sea was diluted with sediment from a clean site to come up with a series of 5 test sediments with dilutions from 1:32 to 1:1024, and the reference sediment. The 1:32 dilution of the test sediment was analyzed for organotins (2862 µg tin [Sn] kg dry wt –1), polycyclic aromatic hydrocarbons (6064 µg kg dry wt –1), and selected trace metals (e.g., copper 352 mg kg dry wt –1). The survival rate of G. fasciatus (10‐d toxicity test) was 100% in the reference and 1:1024 treatments, and began to decline from the 1:256 dilution onward. In a 28‐d experiment, various types of morphological malformations were observed in 11 to 80% of the amphipod embryos in the 1:64, 1:128, and 1:256 dilutions, with only <5% in the reference treatment. Also, elevated activities in the antioxidant defense system enzymes glutathione S‐transferase and catalase were observed in amphipods exposed to the contaminated sediments compared with the reference treatment, with responses at lower contamination levels compared with the appearance of malformations in the embryos. The results obtained illustrate the effectiveness of the combined application of embryonic malformations and antioxidant defense system biomarkers in amphipods in the assessment of sediment toxicity, and potentially also of sublethal effects of chemical contamination in aquatic ecosystems.
