Bioavailability and remineralization rates of sediment-derived dissolved organic carbon from a Baltic Sea depositional area by Monika Lengier, Katarzyna Koziorowska-Makuch, Beata Szymczycha, Karol Kuliński

“…This pilot study investigated the bioavailability and remineralization kinetics of the sediment-derived dissolved organic carbon (DOC) from the Gdańsk Deep, a depositional area in the Baltic Sea. This was assessed in the long-lasting (126 d) incubation experiment, in which the mixture of DOC from sediment pore water and bottom water was exposed to oxic microbial respiration with incubation of bottom water as a control run. …”

Environmental Assessment with Cage Exposure in the Neva Estuary, Baltic Sea: Metal Bioaccumulation and Physiologic Activity of Bivalve Molluscs by Nadezhda Berezina, Alexey Maximov, Andrey Sharov, Yulia Gubelit, Sergei Kholodkevich

“…The use of a triadic approach (bioaccumulation, bioassay, and physiological biomarkers) has been shown to have good applicability for the comparative assessment of the environmental state of the Neva Estuary (Gulf of Finland, Baltic Sea). The novelty of the methodological approach of the study was that it involved both active and passive bio-monitoring methods for assessing the quality of estuarine environment. …”
