Opis:
Ballast water is a significant vector for the transport and introduction of aquatic organisms, microorganisms and chemical pollutants which impacts on ecosystems worldwide. In the study, ballast water from short- and long- range vessels with treatment systems was microbiologically evaluated in spring (April 20th) and summer (July 19th) and compared with waters of the main Police Seaport in the Odra River Estuary, southern Baltic Sea. All collected samples were evaluated for their physicochemical properties by standard methods. The number of individual groups of microorganisms was determined using the indirect culture method, according to the technique of inoculation of serial dilutions of samples of the examined waters. The results showed differences in the microorganisms in analysed samples. The phylogenetic analysis of bacteria recorded from the ballast water of short-range ships in spring showed the presence of six species of the genus Bordetella, while in summer four species of the genus Clostridium. In the ballast water of long-range ships, proteolytic bacteria pre-dominated in spring and halophilic bacteria in summer. In the summer period, eight species of bacteria were recorded, of which six belonged to the genus Clostridium. The ballast water treatment processes used on ships influence the composition of bacterial communities through selective recolonisation of water, which may transform bacterial functions as an important element of the marine food web. On the other hand, the presence of pathogenic bacterial species in the tested samples indicates improvement necessity of ballast water treatment systems used on vessels.

Opis:
Roztoka Odrzańska is the last section of the Odra River estuary. Both in 1996, and in 1999 concentrations of Zn, Cu, Pb, Cd and Hg in the surface waters of Roztoka Odrzańska were within the limits for I class of purity. Maps of the heavy metal distributions in bottom sediments resemble those of TOC distribution in the < 0.20 mm fraction. Overall, 58.3% of the bottom sediments of Roztoka Odrzańska in 1996, as regards concentrations of Cd, Zn, Pb, Cu and Hg, belonged to class IV of purity; 14.6% belonged to class III; 18.8% belonged to class II and 8.3% to class I at all research stations. The excessive pollution the Roztoka Odrzańska sediments is controlled mainly by Cd and Zn concentrations and, to a much lower degree by Pb. Analyses in 1999 showed similar average concentrations of Cu, Zn and Pb, but less than half the content of cadmium. Concentrations, though, of cobalt (1.8x) and especially mercury (22.7x) were higher than the 1996 average levels. The observed concentrations fall within the concentration limits recorded in 1996 for Cu, Zn, Pb, Cd and Co, but they exceed these limits considerably for Hg.

Opis:
The entire estuary water is dominated by the discharge of the River Odra into the Szczecin Lagoon. The water body is brackish and the salinity in the central part ranges 0.5 and 2 PSU. The Lagoon has a long eutrophication history; usually, two phytoplankton biomass peaks are observed: Diatoms in spring and blue-green algae in summer. The recent data on zooplankton is limited. Rotifers and Cladocerans supply the bulk of the zooplankton biomass. The ichtiofauna is composed of fresh and brackish water, migratory and marine species. Zooplankton and water samples were collected during 2003–2005. The results suggest that during 10 season’s climate in Odra River estuary, Cladocera were the dominant group, large impact on the density of mesozooplankton were: Daphnia cucullata and Daphnia longispina, Copepoda played a lesser role in the Odra River estuary than Cladocera. Biomass of mesozooplankton from the Lagoon was significantly higher compared with the biomass of mesozooplankton from Odra River estuary, which could be related to a greater inflow of nutrients into the Lagoon and the increased growth of phytoplankton, which forms an excellent first stage food web for herbivorous and carnivorous zooplankton, and fish and consequently cormorants.

Opis:
Water and sediment in ships’ ballast tanks provide habitats for various organisms, and thus facilitate alien species introductions. Ballast tank water and sediment of 19 ships docked in the GRYFIA Szczecin Ship Repair Yard (Szczecin, Poland) located in an area connected with the River Odra estuary (Southern Baltic), were sampled in 2009–2011 to find out if the ships could be vectors of species introductions to the estuary, already known for the presence of non-indigenous taxa. This study showed the ballast water of the ships examined to house rotifers, copepods, cladocerans, and bivalve and cirriped larvae – common constituents of zooplankton assemblages in coastal waters. The ballast tank sediment supported meiobenthic foraminiferans, nematodes, harpacticoid copepods, turbellarians, bivalves, polychaetes, and chironomid and cirriped larvae. It is not possible at this stage to judge what meiofaunal taxa constitute an alien component in the estuary biota. Macrobenthos in the ships’ ballast tank sediment examined was represented mainly by nereid polychaetes. Although the unintended “biological cargo” examined proved quite diverse and abundant, it contained few identified alien taxa. It does not seem likely than any of them could pose a threat of a biological invasion in the River Odra estuary. However, numerous species remained unidentified, and therefore assessment of the risk of alien species introduction and invasion contains a large measure of uncertainty. On the other hand, the risk as such remains, since the density of ballast water-borne organisms in all ships exceeded the allowed limits.

Opis:
The content of Cu, Zn, Pb, Co, Cd and Hg accumulated in water, mollusc shells and 15-cm layer of bottom sediments in Lake D1bie, Domi1?a and Roztoka Odrzanska is analysed. The metal concentrations range from 99.82 to 99.88% in bottom sediments, from 0.09 to 0.16% in water and from 0.01 to 0.04% in shells. There is some diversity in distribution of heavy metals in bottom sediments of the study areas due to diversity of heavy metal concentrations in the Odra River Estuary. The metal successions in mollusc shells of the three areas under consideration are identical: Zn > Cu > Pb > Cd > Hg. The distribution of metals in water and mollusc shells indicates greater concentrations of metals in molluscs. In particular, when considering the mass ratio, the water mass is greater than the mass of shells, varying from 3100 (Lake Dąbie) to 20000 (Domiąża). The content of metals in the shells ranges from 7.33% to 22.39% of their total amount in the analysed ecosystems.

Opis:
Babka bycza Neogobius melanostomus (Pallas, 1814) jest rybą naturalnie bytującą w basenie pontokaspijskim. Jednak od drugiej połowy lat 80-tych ubiegłego wieku obserwuje się rozprzestrzenianie tego gatunku w wodach Europy, w tym również w wodach polskich. W ostatnim dwudziestoleciu, począwszy od 1990 roku kiedy to po raz pierwszy złowiono babkę byczą w okolicach portu rybackiego w Helu trwa masowe i szybkie rozprzestrzenianie się tej ryby po całej Zatoce Gdańskiej, Zalewie Wiślanym, wzdłuż południowego wybrzeża Bałtyku, a także w Zatoce Pomorskiej oraz estuarium Odry. W 2009 roku odnotowano pierwsze okazy babki byczej w połowach gospodarczych prowadzonych w jeziorze Dąbie. Obserwując inwazję babki byczej w polskiej strefie przybrzeżnej Bałtyku oraz estuarium Odry należy postawić pytanie czy zjawisko to może być dla człowieka ekozagrożeniem czy wręcz wzbogaceniem jego środowiska?
Round goby Neogobius melanostomus (Pallas, 1814) is a fish species of Ponto-Caspian basin origin. However, since the second part of the 80’s of the last century has observed spreading of this species in European waters, including in Polish waters. In the last two decades, from 1990 when it was first caught of round goby near the fishing port in Hel, takes a massive and rapid spread of this fish throughout the Gulf of Gdańsk, Vistula Lagoon, along the southern Baltic coastal zone and the Pomeranian Bay and also the River Odra estuary. In 2009, first round goby in commercial catches conducted in Lake Dąbie was recorded. In this situation the question is that invasion can be a eco-threat or even enrichment of the environment to the human being?
