Nitrate levels in rivers in European countries (2018-2023)

The figure shows the current variation in nitrate concentration among river water bodies in European countries (2018-2023).

The number of river water bodies used for the assessment is given in parenthesis (river monitoring sites for Albania, Montenegro and North Macedonia).

* = Kosovo under UNSC Resolution 1244/99.

Units

Percentage

Additional information

The concentration per river water body is calculated as the average of available annual mean concentrations for the last 6 years. For Albania, Montenegro and North Macedonia, monitoring site average is used instead of water body average. Concentrations are in mg nitrate-nitrogen per litre (mg NO3-N/l).

Methodology

The water bodies are assigned to quintile classes based on the distribution of the 6-year average concentrations, and the results are summarised per country as percentage of water bodies per quintile class.
