BOD5 data used for all countries except Estonia, Finland, Latvia and Lithuania where BOD7 data used. Data are from representative river stations. Stations that have no designation of type are assumed to be representative and are included in the analysis. 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 2002 for all countries except the Netherlands (1998), Ireland (2000) and Romania (2001).
