Development

 

The decrease of nitrogen loading from all sources has been much less significant than that of phosphorus. Relative to phosphorus, the effectiveness of nitrogen removals from waste water has remained much lower. Loading from industry has approximately halved since the mid 1980s, but loading from municipalities did not begin to decrease until mid 1990s. By 2006 it has decreased by some 25%.

The volume of diffuse nitrogen loading has not decreased. On the contrary, loading from agriculture into inland waters has probably even increased.
