Set Up

This study aimed to develop scenarios for a further decrease of point source nutrient load in Estonia to achieve the nutrient reduction target levels set up by the HELCOM Baltic Sea Action Plan produced in 2007. A possible reduction in the total phosphorus (TP) and total nitrogen (TN) load has been assessed based on the requirements set up by Estonian and EU legislation as well as the HELCOM recommendations. Scenarios were developed for four urban pollution load classes with different requirements for waste water quality at the outlet of the wastewater treatment plant (WWTP). The results revealed that the load of TP and TN to the sea and to inland surface water bodies can be reduced by 68 and 352 tonnes, respectively, when following the most stringent HELCOM recommendation for the quality of sewerage outlets. These possibly reduced loads form only about 30% of required TP and 40% of TN annual reduction levels in Estonia which are 220 tons of phosphorus and 900 tons of nitrogen. Therefore, further decrease can mostly be made possible by lowering the diffuse load and that can also be problematic.

AbstractIn this review, I would like to summarize the current knowledge on the microbiology of soda lakes and pans of the Carpathian Basin. First, the characteristic physical and chemical features of these sites are described. Most of the microbiological information presented deals with prokaryotes and algae, but protists and viruses are also mentioned. Planktonic bacterial communities are dominated by members of the phyla Actinobacteria, Bacteroidetes and Proteobacteria; small-sized trebouxiophycean green algae and Synechococcus/Cyanobium picocyanobacteria are the most important components of phytoplankton. Based on the current knowledge, it seems that mainly temperature, salinity, turbidity and grazing pressure regulate community composition and the abundance of individual microbial groups, but the external nutrient load from birds also has a significant impact on the ecological processes.
