“…A similar dependence was observed for different areas of the Baltic Sea (Witt, Matthäus 2001;Witt 2002). This observation may be an indication that the major part of the HCs are from natural sources, i.e., phytoplankton and terrigenous compounds.…”

Data regarding the content and composition of the hydrocarbons (HC) — aliphatic hydrocarbons (AHCs) and polycyclic aromatic hydrocarbons (PAHs) — are presented in comparison with the content of the total organic carbon (Corg) in the bottom sediments in the coastal area of the eastern part of the Gdansk Basin (Russian sector of the Baltic Sea). The HC and PAH distribution in the sediments confirm the dependence of hazardous substance accumulation on the organic carbon content and the sediment grain size of the affected sediment. Bigger concentrations of PAHs were also observed near the Pionersky port. Particular attention was paid to the PAHs content.

“…By using DNA-based stable-isotope probing, Gutierrez et al (50) identified uncultivated species of PAH degraders associated with a phytoplankton bloom. Although further research is needed to understand why these and other species of PAH-degrading bacteria might be found living with phytoplankton, current evidence correlating the influence of phytoplankton, particularly during bloom periods, with the removal of hydrocarbons from the marine water column suggests that this is a widespread lifestyle (8,9,(51)(52)(53). It has been inferred that the surface of phytoplankton cells can sequester PAHs from the surrounding seawater, subsequently transporting these compounds down to the sea floor by sedimentation (8,9).…”

f A strictly aerobic, halotolerant, rod-shaped bacterium, designated strain TG408, was isolated from a laboratory culture of the marine diatom Skeletonema costatum (CCAP1077/1C) by enrichment with polycyclic aromatic hydrocarbons (PAHs) as the sole carbon source. 16S rRNA gene sequence analysis placed this organism within the order Xanthomonadales of the class Gammaproteobacteria. Its closest relatives included representatives of the Hydrocarboniphaga-Nevskia-Sinobacter clade (<92% sequence similarity) in the family Sinobacteraceae. The strain exhibited a narrow nutritional spectrum, preferring to utilize aliphatic and aromatic hydrocarbon compounds and small organic acids. Notably, it displayed versatility in degrading two-and three-ring PAHs. Moreover, catechol 2,3-dioxygenase activity was detected in lysates, indicating that this strain utilizes the metacleavage pathway for aromatic compound degradation. Cells produced surface blebs and contained a single polar flagellum. The predominant isoprenoid quinone of strain TG408 was Q-8, and the dominant fatty acids were C 16:0 , C 16:1 7c, and C 18:1 7c. The G؉C content of the isolate's DNA was 64.3 mol% ؎ 0.34 mol%. On the basis of distinct phenotypic and genotypic characteristics, strain TG408 represents a novel genus and species in the class Gammaproteobacteria for which the name Polycyclovorans algicola gen. nov., sp. nov., is proposed. Quantitative PCR primers targeting the 16S rRNA gene of this strain were developed and used to show that this organism is found associated with other species of marine phytoplankton. Phytoplankton may be a natural biotope in the ocean where new species of hydrocarbon-degrading bacteria await discovery and which contribute significantly to natural remediation processes.

“…Among the individual PAH compounds, a clear dominance of fluoranthene, pyrene and the four-to six-ring aromatics was observed . Seasonal changes of PAH concentrations were determined by Witt (2002), the highest PAH concentrations were measured in February likely due to higher inputs from combustion sources and slower degradation.…”

ACCEPTED MANUSCRIPT AbstractMicronuclei (MN), nuclear buds (NB) and fragmented-apoptotic cells (FA) were analyzed in mature peripheral blood and immature cephalic kidney erythrocytes of flounder (Platichthys flesus), dab (Limanda limanda) and cod (Gadus morhua) from 12 offshore sites in the Baltic Sea (479 specimens) and 11 sites in the North Sea (291 specimens), which were collected during three research vessel cruises in December 2002 and in September 2004. The highest levels of environmental genotoxicity (frequencies of MN up to 0.5 ‰, NB -up to 0.75 ‰) and cytotoxicity (FA -up to 0.53 ‰) were observed in flatfishes from areas close to oil and gas platforms in the North Sea and in zones related to the extensive shipping and potentially influenced by contamination from large European Rivers (Elbe, Vistula, Oder). In dab from the offshore zones of the North Sea, the levels of nuclear abnormalities were higher as compared to those in dab from the Baltic Sea. Responses in immature kidney erythrocytes were higher than in mature erythrocytes from peripheral blood. MN frequency lower than 0.05 ‰ (the Baltic Sea) and lower than 0.1 ‰ (the North Sea) could be suspected as a reference level in the peripheral blood erythrocytes of flatfish.Keywords: Genotoxicity; Cytotoxicity; Micronuclei; Nuclear abnormalities; Erythrocytes; Baltic Sea; North Sea. ACCEPTED MANUSCRIPT 2 IntroductionSurrounded by European countries, the Baltic and the North Seas are constantly exposed to anthropogenic pressure. With pollution from land-based discharges, coastal industries, municipal outflows, agricultural activities, oil and gas industry (drilling and transportation) and transport activities, thousands of chemicals are entering the marine environment. A large proportion of these compounds are potentially toxic, genotoxic and carcinogenic to aquatic organisms (Jha, 2004(Jha, , 2008. The interaction of genotoxic contaminants with DNA causes various genetic disturbances, which often are irreversible and can be transmitted to the next generations (Depledge and Fossi, 1994;Dixon et al., 1999;Jha, 2004). The analysis of environmental genotoxicity provides early warning signs of adverse long-term effects of contamination. A number of biomarkers have been applied for assessment of environmental genotoxicity and the micronuclei (MN) test,...
