BOD5 concentrations in rivers between 1992 and 2011 draining to different sea regions of Europe
The sea region data series are calculated as the average of annual mean data from 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. There were no stations with consistent data series on BOD7 in rivers draining to the Arctic Ocean. BOD7 data has been recalculated into BOD5 data.
Baltic Sea (139)
Black Sea (124)
Celtic Seas, Bay of Biscay, Iberian Coast (132)
Greater North Sea (136)
Mediterranean Sea (171)
