The Pregolja and the Neman (its basin is situated within four states) rivers are the largestsources of load on the Vistula (Kaliningrad) and the Curonian lagoons from KaliningradRegion, Complex ecological researches of the small rivers were accomplished in 1993-1999,besides the hydrological data bank was replenished due to researches in June 200 I-July 2006,Analysis of monthly average has shown that the load from each studied river (with rareexception only) is directly proportional to size of the basin and to the total average runoffThe condition of these rivers reflects the ecological situation in the significant river waterregime phase area, Hydrochemical parameters reflect a present picture of pollution andsaprobiological parameters characterize a situation in the reservoir for some period of timeinterval before researches, The load from the river is connected with the phases of the riverflow regimes substantially and its different parameters can increase or decrease in accordancewith the changes of underground and superficial nutrition ratio and with the seasonalprevalence of the hydrobionts' vital functions.Thus, one of the criteria for estimating the ecosystem pollution may be the limit; load fromthe river is higher which ceases to be than the exceeding, this means that the load from river isnot proportional to the area of its reservoir, i.e. the river practically looses ability toautopurification.Specific load, i.e. monthly average load from the area unit of the river basin was calculatedand analyzed, The results have estimated the contribution of each river eutrophication of thereceiving water, In particular, load from the Mamonovka and the Prokhladnaya river (theirbasins are partly located in the territory of Poland) concerning the majority of riverparameters was in several times (sometimes in multiple and more) higher than the otherrivers. It was revealed, that the load from the river was substantially connected with anddifferent parameters can increase or decrease pursuant to changes in ratio betweenunderground and surface recharge and seasonality of.

AbstractDistributions of Δ14CTOC studied in bottom sediments collected during 2011–2016 in the Curonian Lagoon and in the open Baltic Sea indicated wide variations of Δ14CTOC values. Laboratory experiments on differential carbon utilization by Pseudomonas putida isolated from bottom sediments were carried out for better understanding of impacts of different sources on Δ14CTOC variations. Preferential glucose uptake (up to 80%) as a carbon source and a rather low (2–10%) inorganic carbon incorporation was found in media with diesel fuel. Pseudomonas putida a specific biomarker analyzed in biomass cultivated on the media with different carbon sources has been used to characterize microbial communities responsible for degradation of organic substances in bottom sediments. Large 14C depletions observed in sediments collected in the Gotland Deep of the Baltic Sea may indicate leakage from dumped chemical weapons.
