Abstract The Baltic Sea is the youngest sea on our planet, the environment of the sea is considered to be unique and fragile. It is affected by various human activities resulting in the impairment of water quality. Riverine nutrient (nitrogen and phosphorus) loads are among the major causes of eutrophication of the Baltic Sea. This study examines temporal trends in water discharge, total phosphorus (TP) and orthophosphate-phosphorus (PO4-P) concentrations and losses from three agricultural runoff monitoring sites in Latvia including Berze, Mellupite, and Vienziemite. The annual datasets of TP and PO4-P concentrations and losses were tested for statistical trends using a nonparametric test - the Mann-Kendall trend test. The timeframe of this study was from 1995 until 2018. The results show a large variety of annual mean concentrations and losses of TP and PO4-P in the study period. No statistically significant trend was detected for TP losses. Meanwhile, statistically significant downward trends were observed for TP concentrations in four out of six study sites and in two study sites for PO4-P concentrations.

AbstractVast quantities of German chemical warfare agents (CWA) were stored in Wolgast, on the Baltic shore, at the end of World War II. Those munitions, together with others collected by allies after the war, were disposed in the Baltic Sea. Altogether, an estimated 50,000 tonnes of chemical weapons were sunk in the Baltic Sea. Official dumpsites are located in the Bornholm Deep, Gotland Deep, Little Belt, and Skagerrak. According to previous studies, several unofficial dumping sites exist on the transport routes from Wolgast to dumping areas and in the Gdańsk Deep (cold war dump).In the years 2005‐2008, the interdisciplinary “Modeling of Environmental Risks related to sea-dumped Chemical Weapons” (MERCW) project performed mapping, (ca. 20% of dumping areas) and addressed some possible ecological risks in official dumpsites in the Bornholm Deep, Gotland Deep, and Skagerrak. The Chemical Munitions Search and Assessment (CHEMSEA) project aims to fill the gaps in MERCW research (mapping using new techniques, sediment contamination study, corrosion estimation), observing temporal trends in the ecosystem (compare present CWA and degradation products to that observed in MERCW), and extend this research to the largest unofficial dumpsite (Gdańsk Deep). Moreover, CHEMSEA will provide a number of guidelines for affected groups and stakeholders regarding operations in bottom areas contaminated with CWA and assess the probability, range, and ecological consequences of CWA release from dumped munitions in the Baltic Sea. The results of the project will be shared with the Helsinki Commission and the project’s partners and associated partners. The CHEMSEA is planned for years 2011‐2014.
