Effects of large-scale changes in emissions on nutrient concentrations in Estonian rivers in the Lake Peipsi drainage basin
Abstract The fall of the Iron Curtain resulted in dramatic changes in Eastern Europe, including substantial reductions in the use of fertilisers and livestock production, as well as a marked decreaseExpand

Regional variations in diffuse nitrogen losses from agriculture in the Nordic and Baltic regions
Abstract. This paper describes nitrogen losses from, and the characteristics of, 35 selected catchments (12 to 2000 ha) in the Nordic and Baltic countries. Average annual losses of N in 1994–1997Expand

Reverse osmosis and nanofiltration of biologically treated leachate
Experiments of nano-filtration (NF) and reverse osmosis (RO) were conducted to remove most pollutants from the biological treated leachate. For example, the purified permeate after reverse osmosisExpand

Reaction of large and shallow lakes Peipsi and Võrtsjärv to the changes of nutrient loading
More than 20-year monitoring of Estonian rivers reveals that the loading of nitrogen to large shallow lakes Peipsi (3,555 km2, mean depth 7.1 m) and Võrtsjärv (270 km2, mean depth 2.8 m) decreasedExpand

The impact of changes in nutrient loading on cyanobacterial dominance in Lake Peipsi (Estonia/Russia)
The influence of changes in nitrogen (N) and phosphorus (P) loadings in 1983-2001 on cyanobacterial development in Lake Peipsi (3.555 km 2 , mean depth 7.1 m) was studied. After the collapse ofExpand

Recent trends in nutrient concentrations in Estonian rivers as a response to large-scale changes in land-use intensity and life-styles.
The aim of the study was assessment of changes in nutrient concentrations in Estonian rivers as a response to improved wastewater treatment and substantial reductions in the use of fertilisers andExpand

Nutrient losses from agricultural areas in the Gulf of Riga drainage basin
Abstract Leaching and runoff losses of nitrogen and phosphorus were measured in four catchments in Estonia and Latvia during the period 1994–1997. The losses varied considerably depending on land useExpand

Nitrogen source apportionment : a comparison between a dynamic and a statistical model
Abstract A dynamic model, HBV-N, and a statistical model, MESAW, for nitrogen source apportionment were compared regarding model performance, model uncertainty and user applicability. The HBV-N modelExpand

Is the destabilisation of lake peipsi ecosystem caused by increased phosphorus loading or decreased nitrogen loading?
Lake Peipsi (3555 km2, mean depth 7.1 m) located on the border of Estonia and Russia is the largest transboundary lake in Europe. L. Peipsi consists of three parts. The shared largest northern partExpand
