nitrogen load to the Baltic Sea--present situation, acceptable future load and suggested source reduction

The problem of eutrophication in the Baltic sea is considered in relation to external nutrient loads, especially nitrogen. The countries within the Baltic's drainage basin agreed to reduce the anthropogenic waterborne input of nitrogen by 50 per cent between 1987 and 1995. Nitrogen emissions to...

Description
Summary:The problem of eutrophication in the Baltic sea is considered in relation to external nutrient loads, especially nitrogen. The countries within the Baltic's drainage basin agreed to reduce the anthropogenic waterborne input of nitrogen by 50 per cent between 1987 and 1995. Nitrogen emissions to the atmosphere were also to be frozen at the level applying at the end of the 1980s or reduced. Of the total nitrogen input, 21 per cent (296,000 tonnes) was atmospheric deposition. The maximal acceptable future load to the Baltic was estimated at 600,000 tonnes per year, a reduction of 57 per cent from present day values. Ways of achieving this reduction are considered.
