Concentrations of nitrate (left, NO3) and phosphorus (right, OP (orthophosphate) or TP (total phosphorus)) in European freshwater bodies in the period 1992-2005.

Topics: ,
Concentrations are expressed as annual mean concentrations for groundwater, and station weighted mean of annual mean concentrations for rivers and lakes

Only stations with time series consisting of minimum seven years are included. The number of stations included per country is given in parenthesis.

Nitrate in groundwater: AT (14), BE (25), BG (63), DE (9), DK (3), EE (5), ES (1), FI (38), GB (29), HU (18), IE (3), LI (1), LT (7), LV (2), NL (9), NO (1), PL (3), PT (3), SE (3), SI (5), SK (10).

Nitrate in rivers//total oxidized nitrogen*: AT (145), BE (23), BG (82), CZ (70), DE (125), DK* (39), EE (53), FI* (131), FR (287), GB* (139), HU (98), LT (64), LU (3), LV (47), NL* (9), NO (10), PL (104), SE* (113), SI (24), SK (52).

Nitrate/total oxidized nitrogen* in lakes: DE (6), EE (5), FI (21), GB (21), HU (16), LT (8), LV (8), NL* (7) NO (92), SE* (181), SL (4).

Orthophosphate in rivers: AT (134), BE (26), BG (64), CZ (65), DE (133), DK (40), EE (53), FI (116), FR (241), GB (69), HU (98), LT (64), LV (47), NO (10), PL (100), SE (113), SI (23), SK (6).

Total phosphorus in lakes: AT (5), DE (7), DK (23), EE (5), FI (207), GB (18), HU (10), IE (7), LT (7), LV (8), NL (7), SE (165).

 

*) Some countries measure nitrate plus nitrite (NO₃+ NO₂) = total Oxidized nitrogen - as nitrite (NO₂) is usually a few percent of total Oxidized nitrogen, we have countries where nitrate is measured using a total of Oxidized Nitrogen
