Table 2. Total nutrient loadings in the Limfjord. Mean values (tons km-2 year-1) and proportions relative to the mean values used for the ecological-social-economic (ESE) model calibration period from 1985-2003.

Nitrogen Phosphorous
T km-2 year-1 % T km-2 year-1 %
1985-2003 mean obs. values 10.3 100 0.44 100
1984-1986 mean obs. values 12.3 120 0.91 207
2010 estimated values 6.8 66 0.28 64

Scaled to normal precipitation.
Values in italics have been suggested by Markager et al. (2006) as the loadings that would be required to achieve ‘good environmental status’ as defined for the WFD.
Values in bold are from the official Danish water action plan targets (§initial proposal from January 2010 and |modified proposal from May 2010, the latter of which is now under public consultation).
