Implementation of Trophic Status Index in Brackish Water Quality Assessment of Baltic Coastal Waters The assessment of the trophic state of marine coastal waters is one of the leading initiatives declared in the European Water Framework Directive (WFD). The Baltic Sea is a semi-enclosed ecosystem which consists of subregions with wide salinity and seasonality gradients. Anthropogenic impact results in eutrophication processes on different scales. Efficient eutrophication control and environmental management in the Baltic Sea, according to WFD, requires a prerequisite of common and sensitive indicators for the European coastal waters including the Baltic Sea. In this article the Trophic Status Index TRIX, recently succcesfully implemented in Mediterranean and Northern European sea coastal waters as a holistic approach indicator, was implemented for the Gulf of Rīga and Latvian Baltic Sea coastal water quality assessment between 1999 and 2005.

This study introduces a prototype model for evaluating measures to abate agricultural nutrients in the Baltic Sea from a Finnish national perspective. The stochastic simulation model integrates nutrient dynamics of nitrogen and phosphorus in the sea basins adjoining the Finnish coast, nutrient loads from land and other sources, benefits from nutrient abatement (in the form of recreation and other ecosystem services) and the costs of agricultural abatement activities. The aim of the study is to present the overall structure of the model and to demonstrate its potential using preliminary parameters. The model is made flexible for further improvements in all of its ecological and economic components. The results of a sensitivity analysis suggest that investments in reducing the nutrient load from arable land in Finland would become profitable only if the neighboring countries in the northern Baltic committed themselves to similar reductions. Environmental investments for improving water quality yield the highest returns for the Bothnian Bay and the Gulf of Finland, with smaller returns for the Bothnian Sea. Somewhat surprisingly, in the Bothnian Bay the abatement activities become profitable from the national viewpoint, because the riverine loads from Finland represent a high proportion of the total nutrient loads. In the Gulf of Finland, this proportion is low, but the size of the coastal population benefiting from improved water quality is high.;

This report focuses on the studies o f the bathing water microbiological quality in Latvian coastal zone of the Baltic sea and the Gulf of Riga in May-October, 1998-1999. The microbiological studies has been done in the different coastal zones of Kurzeme and Vidzeme, downstreams o f small rivers and biggest rivers Venta and Gauja, discharges o f wastewater treatment plants and the public bathing waters in Ventspils and Saulkrasti municipality area to assess their quality according to the EU Blue Flag and Latvian National Standard criteria. The microbiological examinations were carried out in accordance with the International Standard Methods. A complex of indicatororganisms - total and thermotholerant coliforms (E.coli), streptococci, and heterotrophicplate count (37°,21°C) has been tested. Water quality in the Kurzeme has been found much better on the beaches of the Baltic sea than the most urbanised beaches of Gulf o f Riga. The quality o f the Ventspils public bathing waters has been evaluated as very good (80-100% o f data). Whereas as a result of anthropogenic load only 61-82% o f data conforms the obligatory requirements of the bathing water quality in Saulkrasti coastal zone. In the study the microbiological pollution, sources and levels of their dynamics and hydrological factors are interpreted. The colour maps o f the bathing waters quality are presented.
