| 210Po accumulation by five species of the Black Sea molluscs inhabiting the Sevastopol bays was studied. 210Ро concentrations in investigated mollusks vary widely and depend on the type of their nutrition. The highest concentration was found in the Far-Eastern giant oyster and the lowest one – in nana. 210Po accumulation by the Black Sea mussels depends on their individual wet weight (WW), the stages of maturity of the gonads and inhabitancy condition. Such dependences were found for the Far-Eastern giant oyster. Concentration Factors (CF) of 210Po for the Black Sea molluscs vary from 7x10^3 to 5.2x10^4. This is in good agreement with World Ocean average value for 210Po CF for molluscs which equals 3x10^4. |

| To estimate methane flux from natural gas bubble streams (seepages) a combined approach was applied, inclusive of detailed echo survey of investigated area and data analysis with the use of specialized software, GIS technique and mathematic simulation. A precise location map of methane seepages in the Dnieper paleo-delta region was obtained. In total 2200 seepages were identified at the investigated area of 378.1 sq.km, which release 16.74 106 m³ at atmospheric pressure (STP), or 12.0 10-3 teragram (Tg) methane a year. Statistical distribution of individual seepage methane flux rates conforms to the lognormal law. We found that 1.9 % of methane from gas bubble streams reaches the atmosphere in gas phase, while 98.1 % dissolves in the water column. Thus,... |
