BOD7 data from Estonia (EE), Finland (FI) and Lithuania (LT) have been recalculated into BOD5 data. The number of stations with annual means within each concentration band are calculated for the latest year for which data are available. The latest year is 2006 for all countries except Albania (AL), Bulgaria (BG), Italy (IT) and the United Kingdom (GB) (all 2005), Greece (GR) (2004) and Cyprus (CY) (1999).
