Policy issue: Are nutrient policies resulting in cleaner rivers?
Ammonium levels have fallen in European rivers of all sizes since 1990. The largest rivers show the highest concentrations, reflecting the fact that the main sources of ammonium - sewage treatment plants - are not usually located on small rivers.
The fall is directly attributable to improvements in these plants, although levels are still above the 'natural', or background level.
The United Kingdom, Denmark, Finland, and France saw the lowest concentrations at their monitoring stations, with Austria and Belgium at the other end of the scale.
