Freshwater quality

This indicator shows:

1. Annual median concentrations in rivers of Biological Oxygen Demand (BOD) and ammonium (NH4).

2. Trends in concentrations of orthophosphate and nitrate in rivers, total phosphorus and nitrate in lakes, and nitrate in groundwater bodies.

Units

The concentration of nitrate is expressed as mg nitrate (NO3)/l for groundwater and mg nitrate-nitrogen (mg NO3-N/l) for rivers and orthophosphate and total phosphorus as mg P/l.
