Nutrient load
In comparison with other rivers, the greatest
loads from transboundary pollution in 2000 were to the Venta basin.
The total nitrogen discharge from Lithuania was 90% of the total
discharge to the sea.
The total phosphorus discharge to the Venta River
from Lithuania was 90 t, which is identical to the total
phosphorus discharge to the sea.
Nutrient concentrations
In recent years, the total phosphorus
concentration in the Venta has decreased, from 3.14 mg/l in 1995
to 2.07 mg/l in 2000.
In comparison to the nitrogen concentration, the
phosphorus concentration in the Venta has slightly increased, from
0.044 mg/l in 1993 to 0.058 mg/l in 2000.
