The sea region data series are calculated as the average of annual mean concentrations for river monitoring stations in each sea region. The data thus represents rivers or river basins draining into that particular sea. Only complete series after inter/extrapolation are included (see indicator specification). The number of river monitoring stations included per sea region is given in parentheses.

Get in shape and be friendly to the environment all at once!
Journeys of less than 3 km may take less time if you walk, use a bike or even take the bus. If taking your kids along, try using a skateboard, skipping rope, rollerblades or buggy boards! Remember how much fun it was when you were a kid.
