Percentage of river stations per country with significant increasing, stable or decreasing BOD trend between 1992 and 2006
- 01 Feb 2008 - Trends in BOD concentrations at river stations in European countries between 1992 and 2005
- 01 Feb 2006 - Trends in BOD concentrations at river stations in European countries between 1992 and 2003
- 21 Mar 2005 - Trends in BOD concentrations at river stations in European countries between 1992 and 2002
BOD5 data used for all countries except Estonia (EE) and Finland (FI) where only BOD7 data used. BOD7 data from Lithuania (LT) (1996-2006) and Latvia (LV) (1996-2001) have been recalculated into BOD5 data. Time series trends calculated, using only stations that have recorded concentrations for at least seven of the years included in the time series. Sen&#39;&#39;s Test then applied to determine statistically significant trends in the data (see Methodology section for further details).
